Hi there. I have dug out my 30yr old Frog. When I plug in the power, the motor runs at full belt. Can anyone shed any light on what the fault could be. many thanks

this is my first post on the forum and have recently completed my re-re frog and am wandering on a cheap and good upgrade for it (not ballraces please).

Hi everyone. Just a heads up, I have been in contact with Don regarding his .50 caliber customs CNC rear ORV arms, and he is now considering the option of another parts run if there is enough interest. He is going to contact some local machine shops to work out minimum numbers and minimum pricing required and take it from there. Obviously the rear swing arms are the crown jewel item, but other possible parts if it goes ahead are steering blocks, front arms, rear shock mounts, rear body post brace, and motor cover. Some links to show examples of his parts - https://www.worthpoint.com/worthopedia/tamiya-frog-brat-orv-aluminum-468167415 https://www.worthpoint.com/worthopedia/tamiya-monster-beetle-black-foot-mud-440019891 https://www.worthpoint.com/worthopedia/tamiya-vintage-blackfoot-monster-481068476 https://www.worthpoint.com/worthopedia/tamiya-monster-beetle-black-foot-mud-401325750 https://www.worthpoint.com/worthopedia/tamiya-frog-monster-beetle-blackfoot-132398427 https://www.worthpoint.com/worthopedia/tamiya-frog-brat-blackfoot-monster-137667539 https://www.tamiyaclub.com/trades_model.asp?cid=97760&id=23382 Don's plan once he knows minimum cost and numbers is to start a go fund me page to raise the capital required. He is happy for me to share his email address so any questions can be sent directly to him, but please genuinely interested inquiries only - Don McAtee - mcateedon@gmail.com Lets all support him on this and cross our fingers in the hope that it goes ahead Cheers, Dave.

Evening folks. I have built many cars over the years- and was an avid racer in the 80s. I have 4 Tamiya hornets, 3 Kyosho Ultima 2s, an original Ultima, a Lunchbox and now a re-re Frog that is DRIVING ME CRAZY. I always wanted a Frog as a kid so decided to pull the trigger on one as an adult. Everything seemed to go together great. On the first drive (pavement) it was ALL OVER THE PLACE. Stability was horrible. It was almost like driving without the steering rods connected. I have searched forum after forum and went over the build diagrams ten times. I can't figure out what is wrong. I can't imagine this is normal for a Frog! Is it? I have spent hours looking closely at photos from the web of many different builds. The front end looks exactly like everyone else! Any suggestions? I have bearings throughout and used the Tamiya RC Frog 2005 Assem Univ. Shaft kit to prevent the dog bones from popping out. Any suggestions? Help!

Gearbox for the Monster Beetle, although it should be a direct fit for all ORV cars. The design has been tested hard in my MB, through several vintage events and bashing sessions in all weathers. This eliminates the main problem with the car, the separation of the gearbox sides and destruction of the diff. With this transmission the kit diff will hold up to high powered motors without needing to be upgraded. You can also move the motor to set the pinion mesh and change ratios, viewing the mesh clearly through a polycarbonate window. What's included: - 3mm carbon fibre gearbox sides, CNC cut and engraved - CNC machined billet aluminium gear box structure - CNC machined aluminium motor mount plate - Polycarbonate end cap - All necessary additional fasteners inc. hex socket screws all round - Free shipping worldwide £120

http://r.ebay.com/38p1st I found this during my daily EBAY search... What would be the purpose of this??? Are the benefits worth buying this or making one out of spare parts at home??? Thanks, Terry

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

Want to buy: NIB or used (in good working condition) Tamiya Frog "sway bar" or "stabilizer" set for rear. Looking for Trinity #7002, or You-G #TM-8413, or a CRA rear stabilizer set. If you have one you can sell me (USA), please get in touch! Thanks, Terry

Lately I've been working on parts for my re released cars. Here are some gearbox side plates for my ORV, a replacement for the first one I bought in the mid 80's I was happy to see that Tamiya have replaced the hex drives but as most of us know, the side plates are still weak. These plates are machined out of FRP or g10 material with areas around the suspension pivot, battery door pin, motor and bearing holders left at full thickness for reinforcement. I don't plan on making this a production piece since I don't have the time to make them. Anyway, a much more economical and elegant solution is already available from mheald elsewhere in this forum :-)

When I purchased my Lancia Rally years ago, there was evidence that the chassis was original. One of the clues was its gearbox, which had a solid final drive gear and hex-style outdrives and cups. My Lancia has been anything but period-correct since then, so now I offer its complete supplanted gearbox. What you see here is a complete gearbox from an early ORV-chassis Tamiya. This sale features a fully-assembled gearbox; matching hex-style outdrives, driveshafts, and axle stubs; rubber boots; and the plastic pinion gear cover cap (Part C12, not pictured). Also included are two rear suspension arms and complete dampers (not pictured). The gearbox is in used condition and complete, featuring the original solid final drive gear instead of the later differential - a distinguishing feature of a stock Lancia Rally/Subaru Brat gearbox. It is fully assembled but not greased. Part C12 is not pictured but will be included in the sale; two 3 x 27 mm screws will be required to attach a 380 motor, or two 3 x 30 mm screws for a 540 motor. Upon request, a proper 380 motor adaptor can be included in the sale. To my knowledge, this gearbox was built up with plastic bearings. The gears turn smoothly with no binding, and visual inspection reveals minimal wear. The outdrives, driveshafts, and axle stubs are also in used condition, but with intact hexagonal ends showing little wear. The accompanying rubber boots are supple but show a single small hole each at one end, at its widest point. It is unknown to what extent these components were used - I swapped them out for modern CV joints prior to running the model on which the outdrive assemblies were equipped. I am open to offers and trades; however money is a priority given the circumstances under which I am selling these parts. At present, I am looking for approximately $60 CAD, which will include shipping from their location in Canada. I am able to open up this figure to negotiation where a specific shipping cost is requested. Where other currencies are considered, the Canadian dollar will provide a baseline for conversions (and remember that it is weak right now ). I accept PayPal, either marked as 'gift' or with a nominal increase added to compensate for transaction fees. As well as I have attempted to describe these parts, pictures do a better job; thus: One set of axle stub and outdrive is shown here: The other set is in this photo: The condition of one of the driveshaft ends, which inspection confirms applies to both ends of each assembly: I am also including a pair of rear suspension arms. These are in used condition, with a single crack at each damper mount point, but still usable. Plastic bearings will be fitted to these if part of the purchase. Note that I cannot endorse the 'vintage' nature of the arms with absolute certainty. The rear dampers are in used working condition, and are proper vintage parts. Of course, if you wish for more detailed photos and/or have any questions, do not hesitate to ask me! I have ready access to all parts mentioned and wish for you to buy with confidence, so I will be more than happy to answer your queries. Thanks for reading! Edit: Note that I will be absent from May 11th - 28th, so communications will be sparse during that time, and shipments delayed until the 29th.

Hi there, I am after a pair of rear Beetle CVA shocks to put on my Frog (hopefully they are a direct fit?) 80mm long please. Happy with an all white pair so I can dye them. Cheers

Hey All Some of you may have seen my eBay listing for this item but i figured i would try to sell it on the forum as well. I have been parting out my ORV related items to fund other builds. Up for sale is a great package for someone with a Re-release Frog or Brat or Vintage Frog, Brat, Monster Beetle, or Blackfoot. Selling a very lightly used MIP Ball differential that has less that 3 runs on it! These Ball diffs only began selling at the start of this year. You will get: - Assembled MIP Tamiya Super ball Diff Part Number: #16210 - Remaining MIP Ball diff grease - Tamiya ORV Gearbox with all mounting and closure screws - 16 Tooth pinion with set screw and matching spur gear - Tamiya gearbox pinon gear cover with screws - Assembled Tamiya Universal Shaft Kit Part Number 53908 (dog bone ends are in the boot so you cannot see them in the picture) - Tamiya rear axle shaft joint boots - Tamiya rear plastic hubs with drive pins The re-release Monster Beetle and Blackfoot now come with the universal shaft kit. The re-release Frog and Brat need the universal shaft kit to take advantage of the MIP Ball differential. If you have a Re-release Frog or Brat or any vintage Frog, Brat, Monster Beetle, or Blackfoot, this would be everything you'd need to take advantage of this new ball differential setup. Price is $105 PayPal'd and shipped to the US.

Bit of a random one here - and don't think I'm taking this all too seriously, because I'm really not, I just like preparing things properly I've entered my SRB in this years Iconic Revival, but it looks like I'm the only SRB entry. Since there's a few other Frog entries in the '77 - '83 class, I'm considering swapping my entry to my Frog so I can play with the other Frogs. I can't find much about good, functional mods make to a Frog for racing. Way back in the day I made a new upright front shock mount for my Frog which kinda works, but I need to tune the shocks with softer springs. Other than that, is there anything worth doing? I'm prepared to go totally mental, I haven't run the Frog in stock trim in a very long time and found it to be way too tail-happy with a Super Stock BZ installed. It's a re-re and it suffers the famous issue of the front stub axles popping out. Besides carrying a drawer full of spares, is there a known fix? Any other fragile areas worth taking spares for? I'm guessing spike tyres will be best on astroturf. Not sure what fronts to run. For aesthetic purposes I'd love to run Brat wheels and tyres and a Brat shell (it's actually technically a Brat, but I used the shell for something else and always ran it with Scorcher tyres and Baja body) but I guess the Brat tyres will be wrong for an astro track. Again - don't think I'm taking it seriously, I just want it to be as well-behaved as possible, we tried to run the SRB on astro with the Rough Rider tyres for last year's enduro and it was almost undriveable until we switched to spikes.

I just got another set of HPI #2100 front rims in the mail... These came with the front axle adapters, which are getting harder to find... These will get tossed in the spare wheel bin along with several other white pairs, and several black pairs... One more set of #2100s and I'll have (3) complete white sets and (3) complete black sets... And last week I got (7) NOS Pro-Line 2.2 tires in the mail... Road tires mostly, but it did have the Striker II's I've been looking for forever... Can you ever have too many wheels and tires??? Terry

OK, so I've been using some "yeah racing" aluminum oil dampers on my Bushy D (vintage Bush Devil/Super Blackfoot) with standard Blackfoot front-end suspension... Here's an example pix: http://jpegbay.com/gallery/005068524-1.html#1 I haven't been too happy with the dampers, although they look really shiny... They just don't have the same "mushy-ness" as my neighbors Tra**as big bore dampered truck... So I bought some Tamiya 50520 CVAs for the Bushy D... I'm waiting still for them to arrive, but I wanted to start a discussion about these for my own sake... Mine the Tamiya Club database for nuggets of knowledge... Topic 1: I noticed (from reading instruction manuals online) that the re-re MB CVAs (I assume the BF too) use the solid piston with the solid flat-head (BC8), while the 50520 uses pistons with attachable e-ringed flat-heads with holes (1, 2, or 3)... Anyone have any first hand knowledge on a comparison between the different set-ups??? I'm thinking of using the 3-hole flat-head... Topic 2: I also want to jazz up my car. Are there any other colors that I can get the plastic pieces, other than black, yellow, and white??? Do other color CVA shock plastic pieces exist??? I see there are clear blue 50519 parts (???), are there blue or red pieces??? Are these plastic pieces from other cars that I can use to replace the typical 50520/50519 plastic pieces??? Topic 3: Does anyone have any experience with the 50519s on a Frog??? I think I'll need those for my front-end... AFAIK the piston and reservoir lengths are shorter??? These have a clear blue option, as mentioned above??? Topic 4: Hi-Cap Dampers. How cool are they??? Thanks, Terry

I recently purchased a re released Brat kit minus an ESC and have built it up I think well minus the grease in a few wrong places, but we'll keep mum about that. The front suspension is intriguing me due to the lack of a damper. Myself and Ed back in 2001 bought an original Brat off a boot sale and struggles to keep the chassis together due to the front radius arm mountings. So looking at this 'new and improved' version I have just built I can see the radius arm issue is still around. I've seen a few videos on youmeither and the upright kits and printed parts look great. I wonder though thinking how a car's anti rollbar functions, Tamiya would have junked these two parts and gone for a one piece rollbar assembly clamped inside a tube which could have bolted laterally and screwed into the same holes. I'm gonna see what I can do with some bike spokes. I originally worked in electronics engineering and loved R&D so this is hitting my tinkering spot.

Hi Everyone, I am new to this site, new to RC but having a blast with it. It is extremely addictive. Anyways, I bought a beat up used frog. Hooked my transmitter up to it and it ran fine. Of course, this was not good enough. I purchased many hop ups. I got all new parts for the gearbox, new gears, ball bearings, etc. I built the gearbox. I also got the 2005 Universal Shafts for it. I followed the directions (in fact several times). Without wheels on it, the gears are nice and tight, sounds smooth. Once I put wheels on, I hear a grind. This last time I put it back together, I left the boots off to try to see what is happening. It appears that the Gearbox joints on both sides slide out of the gearbox, just slightly. This is enough to make the swing shaft hit the slot in the gearbox joint everytime it rotates, making a grind noise. Has anyone else run into this? What makes this worse is I got so frustrated with it, I put the original hex shafts back on and now they do this as well. Just so you know, The entire rear end is brand new, including the rear arms. HELP!!! Thanks.

Hey, I'm building a project I've been thinking about for a couple years. Looking for ideas.... Im going the rat rod look due to the original condition of the body. I've already got about 20 hours into the body.... i need colors. I didn't want to go all black. I am thinking a deep red in the sides and black on the top. Also any ideas for the antenna mount. It's currently mouthed to a monster beetle skid plate with a super Blackfoot antenna holder. additionally, I need a vintage MB window to hide all the innards.

Hello, I'm looking for a pair of rear body mounts for the Lancia rally 58040. They appear to be a bigger size than the frog ones because they screw into the battery stay. Does anyone know if that is true? Does anyone have any? thanks!
