  1. After drooling over the doube wishbone suspension from RC Channel for the lobgest time, I took the plunge & bought 2 sets to build a runner Rough Rider. While the RR is being re re released again, I was impatient & instead bought a Sand Scorcher as the basis for my build. I managed to buy 2 sets of hard bodies & 2 sets ofLexan bodies. Also bought the tires & grey bead lock wheels. In hindsight, should have waited a bit for the RR to hit the market. Gear box assembly done. Ball diff replsaced the straigh shaft. Lower arms, hubs & CVDs are RC Channel (RC) parts Only the upright roll cage & T joints are Tamiya bits. The rest are RC parts. Note the upper wishbones Roll cage & rear shocks attached. Take note the original plastic motor cover needs to be modified to accommodate the upper arm but thi RC Channel aloy cover avoids that. The manual form RC channel is not that great. Had to look at pics formt their web site and fill in some blanks myself. Hopefully, these pics can provide some extra info if one is working on a similar build. The button head bolts for the upper wishbone should be 16mm but only 14mm ones were provided. I installed 16mm pieces.
  2. Like most I love the SRB and refuse to accept that it is challenged to handle well in turns or speeds. With the RChannel suspension, the handling is night and day better.. and softening the suspension helps a bunch with keeping it planted. I am able to do full speed turns with the solid axle on asphalt and it will not flip over!!! So next up was pushing for more speed. Couple of years ago, I managed to get a Novak 13.5 brushless in there, top speed was so so. A few weeks ago, I dropped in a viper 10.5. Well that pushed it to the limit, had to be gentle on throttle. Nonetheless I took the SRB to the beach along with my sons outlaw rampage. I managed 5 minutes of runs on the soft sand before it started to glitch.. sensor wires had picked up moisture, so game over for dad. So I thought, either I have to go back to a brushed motor or pick up a sealed sensorless brushless. My sons Rampage had a 13T team brood black can. It looks like a mabuchi but it’s black, has bearing and internal fan (crawler style). It has some kick. So I ordered one and dropped it in the SRB. It had decent speed but nowhere near the 13.5 brushless. So I got to thinking about gear ratios. What if I could switch to 48 p or 64 p and drop the gear ratio. Easy enough task as the SRB output shaft uses a cross pin, so just would need to fine the right bore spur holder. I had a spare XV01, so I checked that, hole was a small, would have to be drilled out. So I grabbed my phone and searched eBay for Sand Scorcher gear ratio. Low and behold there was a Thorpe spur gear older and asking price wasn’t obscene ($16).. So I picked that up. Well it arrived today so I started tinkering. I didn’t have enough 48p gear, so I switched to 64p. Pinion wise the biggest you can use is a 42t (64p) which clears the upper and lower screw holes for gear cover. Spur to match would have to be about an 84t, which I didn’t have. I did have an 88, so I used that one mated it with 36t. Mesh was perfect. FDR dropped from 6.5 for the (20/65) to 4.88! Placed gear cover back on and the gears cleared it perfectly. Took it out for a spin.. now we’re talking.. had very good speed. Drove it hard for a bit and temped the motor.. 140°F.. so not bad! Hmmm 🤔 what to do now
  3. Grastens Builds the: A memorable build of great personal significance begins! Overview (aka Grastens' Understanding of the Buggy Champ and its Predecessors) The Tamiya Buggy Champ was released in 2009, as a re-issue of the original Rough Rider that first appeared in 1979. Along with the Sand Scorcher, it played a role in the popularization of off-road RC buggy racing. The chassis featured full cast-metal independent suspension, which emulated the Volkswagen Beetles that was the basis for many dune buggies of the time. As such, the performance was also quite similar to the full-size subject, which at the time represented an improvement over the current state of off-road RC buggies. The Rough Rider in particular was based on the Bob Maynard Racing Funco SSII, and was set to become a properly-licenced version of his bright-orange racer. However, the deal fell through during the prototype stage, and as a result, the name was changed to “Rob Mitchell Racing” (Tamiyabase has some more information on this for further reading). If nothing else, this footnote reaffirms Tamiya’s attention to authenticity in those early days of their RC venture. The suspension was not the only factor influencing its scale performance: the use of a water-resistant mechanism box to protect the electrical components from moisture damage also allowed the buggy to tackle the elements. This opened up new possibilities for running, which contributed to the chassis’ popularity among more casual enthusiasts. The bodywork did require some deviation from the original Funco buggies to fit the mechanism box, but for all intents and purposes the Rough Rider was an authentic dune buggy at 1:10 scale – and a fraction of the price! The combination of scale aesthetics and performance was befitting the “Model Suitable for Radio Control” philosophy that Tamiya’s nascent RC department sought to embrace. With pronounced positive rear camber and no rear differential, the Rough Rider was really best suited for sandy beaches and dunes – again, like the real thing. As mentioned, the chassis was also used for the Sand Scorcher, which took the Beetle theme even further by introducing a modified Volkswagen-style shell over the original platform. Later, Tamiya would use the chassis underneath a Ford F-150 Ranger body as its own release. In response to the growing number of racers using these buggies, Tamiya would eventually develop the chassis further for the Super Champ (now around today as the Fighting Buggy). The chassis became known as the SRB (Special Racing Buggy), and for all its innovation, there were plenty of improvements that could be made to increase its performance. It has been written that the Rough Rider and Sand Scorcher may have created the “cottage industry” of aftermarket parts (think Team CRP, MIP, Thorp, etc.) as enterprising builders and racers sought to gain the edge on the track. Popular upgrades included items such as lightweight suspension arms, alloy chassis plates, parts to replace the mechanism box with a lighter solution (addressed later with the Super Champ), and an ever-increasing variety of wheel and tire combinations. The legacy of the Rough Rider (and Sand Scorcher) may be similar to that of the later Grasshopper and Hornet, which also brought off-road RC cars to a wider audience. As buggy design evolved into something quite different in the name of outright performance, the scale appearance and driving characteristics of the SRBs remain part of a past era, though revived in other genres such as trail driving! Grastens and the Buggy Champ I bought my Buggy Champ at the local hobby shop (back then, Advance Hobbies near Toronto, Ontario) for what was probably $350. I had been in the hobby for about one year, having started with another Tamiya: the Toyota GT-One on the F103RS. I enjoyed it immensely, and a whetted appetite was now eager to try off-road buggies. At the time, I had little clue as to what the Buggy Champ represented. I found myself living the experience of a Rough Rider enthusiast: once marvelling at its performance off-road, I sought to improve its overall handling by introducing new parts. The modifications I remember the most were the alloy chassis plate, the ball differential, and a succession of coil-spring dampers that replaced the leak-prone originals. I had even considered the RC Channel double-wishbone upgrade for the rear suspension, if only because I found the positive rear camber made handling tricky, and the wear on the outsides of the tires was not looking good… Life intervened, as it usually does, and for a period, the Buggy Champ sat along with my other cars on the shelf. Over time, it was joined by others, and as the on-off relationship with the hobby continued, the car saw less and less action – I would be too engrossed with other projects, like the Lancia Rally that I had taken on and with which I began my love affair with RC rally cars. Unfortunately, life then saw me sell the Buggy Champ (along with the shell for said Lancia Rally) when I needed the funds for a trip. I sold the car to another member on TamiyaClub, who, like me, had been looking for a fun and reliable runner. Perhaps it is best that I have since forgotten this member’s name (and I believe this member no longer frequents the forums), for it broke my heart to learn that this member decided it was not to his taste and sat it on the shelf. I had given him a bargain for it, too… It was at that moment that I came to realize my mistake, though it would take some more time to regret it (after all, it was a good trip!). The Intervening Years Over time, while moving a well-loved car for pocket change to someone who did not appreciate it still hurt, I could also understand that the Buggy Champ was a car best suited for a specific set of conditions. As I grew up and settled down, I would continue to waver between full and zero commitment to the hobby. I struggled with unemployment for an embarrassing amount of time, which definitely affected my ability to continue with my RC cars. Even when I did find full-time work, a diagnosis of clinical depression and the resulting medical struggles changed my life and threw it into turmoil… … And as if in the eye of a storm, I calmly picked up my RC cars again. This time, having finally moved in with my partner and being otherwise completely independent, I found I could focus more time, energy, and (most importantly) money on the hobby that I knew I still loved. The acquisition of a Tamiya Hotshot (courtesy of said partner!) rekindled my interest, and a succession of builds signalled my return to radio-controlled cars. And then: well, where I now live, there is a beach less than an hour’s drive away… Could I really be thinking…? Even with all of the other off-road buggies I have now? A Second Chance Everything pointed me towards another Buggy Champ. Remembering how much I have come to miss my first one, I made the decision to find one – and this time, not let go! Unfortunately, like pretty much everything, the Buggy Champs that were once plentiful online and beyond (namely, the ‘Metallic Editions’ in silver and gold) were now going for way more than I recalled. I had to remember that it had been several years since I last seriously sought one out, but this seemed ridiculous; the majority of them were asking $700 and beyond. The advent of coronavirus inspired me to turn ‘local,’ which is to say to the local online classified ads. There, I found a seller who had a new-in-sealed-box Buggy Champ for well under what everyone else wanted for theirs, out of Toronto. It was even somewhat near where I grew up… I wanted it, but my bank account did not! I made a deal to put down a deposit on it, following which I would come up with the rest of the money in two weeks’ time. I had it all paid for by the next week, and while perhaps I could have negotiated a better price, I felt grateful to have found a brand-new one in the country that did not cost me half a month’s pay! The other nice thing about buying within the country is that shipping is commensurately fast. By the following week, I had it in my hands! When I opened it up and set out the shrink-wrapped box, I just stood there, staring at it: while I may never find my original Buggy Champ again, I have been given another chance to experience it. With the experience I had accumulated with other models in that time, I would appreciate it more than I ever could have back then, and now know better than to part with this one – would you believe I embraced the box and told it I would never let go? I was unaware of the full extent of my emotions until the day it arrived. Maybe it will become a nice memory of mine in this hobby. The Kit Many of you have seen a Buggy Champ before, but for the Gamilans, Betelgeusians, generally-uninformed, and nostalgic types like me out there, I have some photos: Would you also believe I found the box smaller than I remembered? The beauty of a new-in-box example is that I can relive the build, too! That blister packaging brought back so many happy memories: Beneath the blister pack with the tires, there is a special box, decorated with photos of the Buggy Champ in action. The contents of that box: Essentially, it contains all the hardware and most of the main chassis pieces. Under the blister pack with the cast-metal suspension parts, we have the grey three-piece wheels. Sitting in the centre compartment in bags were the bodyshell, the rear bumper, body parts, mechanism box, and the kit-supplied ESC: At the very bottom are those famous box-art decals: And thus, the kit! It will go together in a manner unlike many modern offerings, which I look forward to! The Build The Rough Rider and Sand Scorcher were popular in their day, and the Buggy Champ and re-released Sand Scorcher also enjoyed a following. However, in over a decade since they were re-released, the supply of non-LiPo batteries compatible with the kit’s mechanism box had seemingly gone from small to infinitesimal… There are still several offset-hump Ni-MH batteries available in Europe, and I found myself importing three of them from the U.K. specifically for this model. With the first one, I had the local hobby shop (again, Advance Hobbies) produce some for me from two standard stick packs I supplied. Far away from them or any other suitable hobby shop this time, I went overseas. My experience with the first one showed me that I could not make good use of a ball differential in the back, but that the alloy chassis I had purchased was definitely useful. I found one online, and decided to pair that with a smaller metal bumper for this kit. The electronics I will be using: Pictured are an aftermarket Spektrum-compatible receiver, an old HPI SF-10W servo, an Axial RC LED module that will allow me to fit lights, and a Tamiya TBLE-02S ESC. The last-named is of great confusion to me. I clearly recall my first Buggy Champ being issued with the TEU-101BK, and thought that the original re-issue’s run (excluding Metallic Editions) predated the TBLE-02S completely. There is a thread on TamiyaClub stating that kits are not shrink-wrapped at the factory, so I have no illusions about that. However, is this really as the kit had arrived? While I was at it, I purchased some Sand Scorcher body accessories: The plan had been to use the exhaust pipe from this set on the back of the chassis, though it looks like the Buggy Champ was not issued one for good reason: it is likely not to fit with the shell on the chassis… The build will therefore make use of an aftermarket front bumper and metal chassis plate, but will otherwise be mechanically-stock. LEDs will be equipped using a leftover sprue full of light buckets and lenses from my Comical Avante build, which was a suggestion from Tamiya’s release of the sprue as its own hop-up part. At this juncture, I intend to use the kit-supplied decals, but will not use the suggested TS-12 Orange for the paint. For body colour, I actually have a few options that do not require more purchases: on hand, I have cans of TS-43 Racing Green (the colour I used for my first Buggy Champ, I think), TS-35 Park Green, TS-15 Blue, and TS-8 Italian Red. I even have enough TS-26 Pure White and TS-7 Racing White if I feel so inclined, but at present, I do not. The Racing Green would evoke my first buggy, though the possibilities of the other colours I have are compelling – a decision I am happy to mull over while I build the chassis. The rare revisit of a memory is the subject of this build thread. Onward!
  4. I know the the DT-02 Rough Rider has been done and posted here before. I am only recently returned to the hobby after rediscovering my 35 year old Hornet from my racing days as a kid. After restoring the Hornet back to its former race condition, I decided I needed a project and a cheap build. The DT-02 Holiday Buggy did the trick. I read all the complaints and detractors of the "re-release", but I wanted the chassis.. I had no intention of leaving it stock and I already had bearings, shocks, and a motor for it from buying extra and wrong parts for the Hornet. In conversation with some FB group members I found that classic RC10 bodies fit the DT-02 almost like they were mad for it. So I got to work on a few different bodies for it. The final look is what I called the Rough Raider tribute! I love this chassis. I hope you enjoy! Thanks for taking a look!
  5. Since this seems to come up every once in a while, I thought I would write this all down in one spot for the sake of posterity. SRB (Special Racing Buggy) wheels can be placed into (3) groups: 1. Rough Rider/Buggy Champ. 2. Super Champ/Fighting Buggy/Sand Scorcher. 3. Ford Ranger XLT/Brat. The RR/BC wheels are 1.7”, 5 spoke, and silver. The Fast Attack Vehicle uses the same but molded in brown. All of these sets use the square block style road/sand tires. The SC/FB/SS wheels are 1.5”, 5 spoke, and white. These are also used on the Grasshopper, Hornet, and Frog. All of these sets use the same ribbed sand tire on the front. On the rear, the SS and GH use sand paddles, and the SC/FB, Frog, and Hornet use the spiked off road tires. The XLT/Brat wheels are 1.7”, 8 spoke (thanks @mtbkym01), and white. The front wheel on these sets are the same width as the rear so all four wheels use the same square block tire as the rear of the RR/BC. There are some variations to these such as the Jun Watanabe Hornet (black wheels) and the Brat blue edition (black wheels). If anyone else would like to info or corrections, please do so! Also, this might be a good place to list 3rd party manufacturers that made wheels or tires for these cars or in this size range.
  6. Saw a gold rough rider for sale the other day. Decided to make one myself :
  7. Hi, I am new to the Forum and signed up to help me learn a bit more about the original Rough Rider i recently purchased and also hopefully source some of the broken parts. I am looking for a set of (left and right) Front axle mounts (Part N6) per the original manual. I have attached a picture of mine which are damaged. I believe they are the Mk1 version (please correct me if i am wrong) and would like to replace with the same. Shipping would need to be to Sydney Australia, which of course i would cover! Appreciate it if someone has a set they would be willing to sell. Regards Brent
  8. So my SRB runner was built with a sport tuned motor. I burned the first motor years ago.. so when I replaced it, it went with the smaller spur pinion option. Today, my son was running it in the yard on grass.. after first pack I noticed it was warm.. a few minutes into second pack and car stopped. Motor was definitely hot and smelled crispy! Now a few years have passed between burnt motors but I recalled the old one stopped because one of the brushes had detached. So I looked in armature window and yep, same issue. So I’m now considering other motors options. I modded. Gear box years back to accept a standard brushed can and I’ve seen @Shodog 13t HW EZrun combo. im wondering if there are any other options?
  9. Thought I'd share my TLT based crawler. I should have started a build thread in the builds section, but I got a little ahead of myself. So it's almost done, I'll post any changes going forward. This is my last set of TLT axles, well modified from my crawler. I've had these for a long time, and they have held up incredibly well. The cases are a little beat up, but they still have a lot of miles left in them! I cut a chassis out of 2.5mm 6061 (lower chassis) Front axle was set up with a 3-link and panhard set-up. Originally, I started with a Tamiya Mini X-Acto motor and a double GRU connected to the t-case with a M06 dogbone, though I found it to be a little under geared. Once I had everything sorted, I sprayed the chassis flat black and made a trans mount out of 6mm aluminum. Very solid, no flex here. Motor is low and forward, right where it should be Chassis was designed for a Tamiya LC40 body. I love these bodies, I've got 4 of them in use currently. Decalling them is an exercise in patience but I enjoy it immensely! I had a few issues with the white, it unfortunately was too thin in spots and the backing black bled through. (: Painting is not my strong suit! I decided to power through and used some left over Rough Rider/Buggy Champ decals as kind of a modern take on the Rough Rider theme.. I think it came out pretty good! Other than the questionable paint of course. Compared to my CFX, it has a bit more aggressive stance. I like it... And out on my test course... The tires are not quite the best since they are quite old, but I tried a few other combos, and just thought these looked spot on. I have made a bit of a change to the drivetrain since taking the pics, it's much more trail friendly now. I'm hoping she'll get her first trail run this weekend if the weather holds.
  10. I just finished restoring my 1984 Grasshopper, my first RC car, and while I was in the middle of it, I came across a Rough Rider on Ebay with the original box and Acoms radio. This was the first real RC car I saw as a kid, but I could only save enough to get the Grasshopper. Thirty plus years later, I could afford it so I paid more than anyone else in the world was willing to pay (that's how Ebay works, right?). When I received it I checked over the condition to see what needed to be done. Surprisingly, it's all there and original with the exception of what appears to be a homemade rear cage. Tires are not cracked or excessively worn, but the rears are flat-spotted. Body has cracks at rear corners and nose and the roof is shot. Radio box has a crack at the front bolt, but otherwise is good. The previous owner extended the wires of the battery and on/off switch to the rear of the buggy to allow charging and turning it on/off without taking off the body. I'll have to return that to normal. Overall, it appears to have little use and I'm happy with it for what I paid. Now, I'm thinking about what I want to do to it before starting the tear down. I already have a re-release rear cage and roof. I'm considering just replacing the roof and cage and cleaning everything else, leaving the body with the yellow paint. While it's got some cracks, it has character. My other choice is to strip the body, fix the cracks and do the blue box art scheme. I already have reproduction decals on the way. What do you think?
  11. Hello, I'm new here (I guess you knew that). Very quick intro... I used to use remote control cars approx. 30 years ago (just for fun, not competition), I started off with a Tamiya Sand Scorcher and later also bought a Tamiya Boomerang (1986 ish). My Mum has just moved house and both cars (and kits) have turned up again, much to the excitement of myself and even more so my 6 year old son. Well, all the Boomerang needed was a new battery and we were away but now we need/want a second car (as you all know) to more than double the fun ! For that reason (and to help fund the second car) I've decide that maybe the Sand Scorcher would be better off in the hands of somebody more clued-up and who could appreciate it more than me and my son will (he'll just smash it up I'm sure), So I'm looking to sell it but really not sure where to price it at and also I'm writing this during my (late) lunch break and just realised I don't have any pictures to upload to make this make more sense, sorry but I will post picture later this evening.
  12. Couple of auctions here for some of these nice little replicas made by San-s about a decade ago. Boxed opened (and included), but model unbuilt and mint – as are the cute little leaflets. Buggy champ Frog
  13. Hi all, Ive decided I cannot put if off any longer, I need a SRB in my life... so, in your opinion which would make the better runner - re re Buggy Champ or Fighting Buggy? Both seem to have their pros and cons, having great difficulty in trying to make up my mind, I've watched countless videos! Looking to use on the beach and in the dunes and before any one say's....; no sadly I cannot afford to get both Cheers
  14. Hi, I am looking for: Tamiya RC Buggy Champ / Rough Rider NIB 58441 Will be built so box and blister condition not important. I am in the UK.
  15. I've got a few new old stock brass 20t original pinions for SRB's Champ etc £7 each inc P+P in UK PP gift
  16. I took the rough rider out to the beach with me over the weekend. We built a jump so it could catch some air. I love roosting in the sand. The 17turn motor makes it hook up.
  17. While digging through the RC junk pile, I found an old CRP catalog... DL it here: https://www.dropbox.com/s/8ehh73fs3sjwczq/Team%20CRP%20-%201987%20Catalog.pdf?dl=0 Thanks, Terry
  18. Lots of unused CRP, Thorp and JG part for the Tamiya SRB-chassis (and some other models) for sale. Most parts are without the original packaging, but were never installed and are basically in "as new" condition. Some scuff marks and similar "shelf wear" possible due to high age. Will of course send pics on request so you know the exact condition of what you get! - Aluminum roll-cages - Aluminum rear cages - Aluminum roof and front rollbar for single seater buggy bodies (ie. Rough Rider). (Requires the use of aluminum roll-cage) - Aluminum nerf bars for stock SRB chassis. - Aluminum nerf bars for SRB's with butterfly chassis - Coilovers for original shocks - Coilovers for red 1/8 Kyosho shocks - Rebuild kits for original dampers - Front stabilizers for original SRB front suspension - Front stabilizers for widened SRB front suspension - Rear stabilizers for CRP roll Cage. - Rear damper brackets for mounting 1/8 dampers on CRP roll cage - Extensions for front damper tower - Butterfly chassises - Chassis lowering plates - Ball diffs - Gold anodized aluminum outer wheels for Holiday Buggy tires - Silver anodized aluminum outer wheels for Holiday Buggy tires - Steering kits - Servo mounts - Wide and hardened tubes for front suspension (Gold anodized, but possibly also some silver anodized) - Hardened tubes for stock front suspension (Gold anodized) - Hardened steel rear wheel shafts with aluminum hubs for mounting Holiday Buggy wheels - Kydex bumpers for wider front suspension - Alternative Ratio 48dp spur gears with hubs. - And more. Send me a PM if interested in any of the listed items or if you're searching for CRP, Thorp or JG parts not listed. (don't have much of anything else than parts for the SRB-chassis though!)
  19. I have found an original SRB! It was found dismantled in a shed at an estate sale, looks to be about 90% complete in terms of parts. The odd thing is that the gearbox seems to have some sort of glue sealing it, not much so opening it shouldn't be a difficult task. Would make a fantastic parts car or candidate for restoration. I found the electronics in a separate box, but unfortunately the wires seem to have been clipped. Unfortunate, but they are included if you would like to re-solder or rewire them. Bearings are also included for those that want to make this a running model. As expected the gearbox will need to be shimmed since it has clearly been sitting for a while. I have attached some pictures, and the rear dampeners and the pinion are included, they are just hidden in the chassis tub. Here are the image links: http://postimg.org/image/47u1ap9yv/ http://postimg.org/image/8i8p6af1z/ http://postimg.org/image/5bj7js0xj/ http://postimg.org/image/ak96kjd13/ Willing to let it go for 65$ plus shipping or trade for re-re kits or kyosho mini z optima, show us what you have to offer. The buyer will be responsible for the cost of shipping. I am located in the USA so shipping within the states shouldn't be to much since in this dismantled state it should fit in a large flat rate box. I always ship with a tracking number if possible. I am willing to ship the item out of country/over seas for my UK friends but the buyer will still be responsible for shipping costs. If a trade is made, we will each pay for the shipping of our own piece and we will provide tracking numbers. Otherwise, payments are to be made via paypal only. So let me know what you guys think, at this time not willing to part it out, if nothing happens here I'll just hold on to her.
  20. I have most parts required to assemble roughly 120 SRB-chassises from original release used parts. (Typical fragile/quick wearing parts of course in (much) smaller quantities). From early to late production SRB's, including Super Champ. All defective parts have of course been discarded. Consider selling some parts as I have realized that life is too short to ever need them all. Send me a PM if interested in specific parts. Will send photos.
  21. While my vintage buggy still has all the standard wheels and rubber, i wanted to take advantage of commonly available alternatives so i could put the original stuff away. The rear is simple if you have the re-re axles as they already have a pin layout allowing you to add a 12mm Hex adapter and fit most 2.2 wheels of your choice. However I was still looking at the best options for adding 2.2 wheels and tyres to the front of my Rough Rider, and wanted to share my journey and solution. The twin challenges were getting rims that were bearing enabled, and extending the axle out enough so the new rim didn't interfere with the steering upright. I found some JConcepts rims for the front that are meant for Team associated models (they take an imperial bearing but a 5x9x3 with a small shim or loctite still works fine), but they still needed to be spaced out far enough that there were too few threads for the nut. So I needed an axle extender. I could have ordered the CRP extenders but with the Sth pacific peso heading south daily, and me being too impatient to wait for up to 30 day delivery, I looked around for some alternative options. I usually start this kind of DIY bodge with the thought of "what can I repurpose" rather than starting from scratch. So I looked at the problem from 2 directions was there something with an M4 thread to screw onto the existing axle that had an OD close to 5mm, or was there something with a 5mm OD to match the axle OD, that could be tapped for an m4 thread. In the end I tried both methods. Option 1 - M4 threaded inserts I found threaded inserts (rivnuts) with M4 threads and a 6mm OD at a local hardware store The rivnuts threaded on to the existing front axle just fine, but obviously the outer diameter was too big to allow my bearings to fit. Not having access to a Lathe, I was wondering how to manage this when it struck me that using a spare rear axle as a holder, I could put the whole lot in a drill, and with gentle pressure use a file to take the 0.8mm I needed off the OD. This turned out to be easier than expected; This worked out fine, but with a largish overhang from the part not reduced which I would take up with a washer and spacer. Option 2 - 5mm OD spacers Coincidentally I found a second option in an electronics store in the form of 5mm steel "stand-off" spacers. These hold a circuit board off another, and were hollow with a 5mm OD, so then needed an M4 thread in them. While I've never used a tap to cut a thread, I did have a set, so figured since they were so cheap, I could probably afford to mess around some. In the end it was again pretty straightforward and seemed to have worked fine. I threaded them full length so I could use an M4 bolt to hold a washer and spacer at the other end. The advantage of this method is that I can easily cut the extension to size, which is not as easy with the rivnuts due to their shape. At the moment I have it at a length that means I add a small spacer and washer to hold the bearing in. I'm waiting until I get the slightly larger bearings before I cut it down to exact size, but have loctited them to the axle so they don't unwind on reversing. The total cost of the rivnut method was ~A$5 (or 25c a piece if you made all 20 into extenders), and the standoff method was a little higher at ~62c a piece. This compares to about A$19 if ordered off ebay, plus i got to install and use them about 1 hour after i started the project.. Here's the end result on my buggy. Hopefully this helps someone else.
  22. Hi all, I have just rekindled my RC passion after rebuilding my Vintage Rough Rider, and as i had relied on this site for the knowledge i no longer had, i wanted to share what i had done, and hopefully contribute to the body of wisdom on the site. My Rough Rider was bought as a present for my birthday in 1980, and after i left home for Uni it stayed in its box for the next 30 plus years. So i am probably one of the lucky ones in that i still have my 1st and only Tamiya. I remember the original build, the painting and anticipation of getting to run it first time, only to send it careening backward into a wall and smashing up the rear cage. At the time i lived in Asia, then moved to provincial NZ with my parents before we returned to Australia, so there was a period where i couldn't access any spares or even knowledge (pre-web for you kiddies in the front row). This only dawned on me when i wondered why i hadn't replaced some items, or left some relatively simple things unfixed. The spur to get it out from its cupboard location was i had decided it would be a father /son resto project and on my sons birthday we carefully took it down, open the box, unwrapped the tissue paper, and started to assemble it so we could take an inventory of the needed parts. In the waiting period, my Sons generous Auntie decided she wanted to make a splash and offered him the chance to forego future presents for a few years, in return for a big gift now. I now think its a big win:win as he ended up with a tough-as-nails Traxxas Telluride, and i ended up with a new project (and a more sympathetic driving style) and we still get a shared interest. I wanted to share the unboxing and in another post, will detail the mods I've now made to improve stability, drive-ability and performance. I've linked to the images on Flickr so hopefully they display ok. Original box kept everything together and protected I still had the original Tx also All wrapped up, i'd had the smarts to remove the tyres so they didn't flatspot. Original battery can be seen, plus my box of spares and tools. The chassis was ok but grimy, and all the broken parts i couldn't afford to repair or didn't know how to fix were still broken. I believe this was a "mod" to keep the balls from popping out of the arm sockets A home made servo saver horn after i couldn't replace it locally at the time. The AA batteries are new, but all other electrics are 1980's new! Assembled and in its faded glory I was waiting on a new battery assuming the old NiCad was stuffed, when i stumbled on a charger with the Tamiya connector. On a whim i connected the battery and let it charge for about 6 hours and was blown away that when connected the whole system ran fine (slow, but fine). That gave me the confidence to move forward with a Brushless conversion knowing that the servos had survived the ages, the Tx/Rx still worked ok, and the rest of the electrics werent corroded beyond repair. This project has always been about getting a vintage much loved buggy into a state where it didn't embarrass itself and would let me share quality time with my son. That's why you won't see any detail about repairing the body shell, or getting period correct tyres or wheels. But......recognising the historical value many attach to the Rough Rider, all mods i have planned or have already been done are non-destructive with the aim that it can be returned to its factory self by the next person. Any pieces i removed or were damaged, have just gone into the box for the next owner (although there are no plans for a sale while she's a healthy runner !! ). Cheers and thanks for YOUR help in getting it back to a fit state. RMR110 PS i had a chance to get it onto the beach soon after i got a new battery Motor and tyres, and uploaded it to YouTube. Unfortunately while this was the best footage, it was also when i had removed the body shell and in my haste to hit the beach before we lost the light, i didn't put it back on, so she's in stealth mode.

  24. As much as it annoys me when I read a post that starts with "Testing the water with this one, not sure if I want to sell it"... that's what I'm doing here. I'm listening to interest and good offers out there. I could do with raising cash to fund other purchases I want to make. This is the rarest SRB hop there is, in my opinion, and it has never been mounted to a chassis. Converts the SRB chassis into 4WD.
