ThunderDragonCy posted a topic in The BuildsShifted this thread over here as I posted in General Discussions as my first post before I knew about how things worked. Also, work on the car escalated and I wanted to keep a note of ongoing upgrades/changes. Hopefully of interest to DT03 runners/buyer. I have an original Thunder Dragon from 1988 which has had a bit of a restomod, but getting that sorted recently led to the purchase of a cheap Racing Fighter from Germany as I've never had a 2WD buggy before. First buggy full build in about 30 years, although the Thunder Dragon has been torn down and rebuilt several times. Really enjoyed it. I had an old Grasshopper2 shell in my bit box from back in the day, and I'd never painted a shell before. I don't like the modern look of buggies, being a child of the 80's I love the older buggies so I decided to have a go and some light body mods to fit it to my DT03. It was already slightly modified around the front shocks to fit on my Thunder Dragon. Here's a couple of trial fits with the primer on, trying to figure out the mountings and proportion. Couldn't resist getting the wheels on to see what it might look like: Figured out the body mods, enlarging the front hole to use the central front mount on the chassis, and adding holes in the haunches for the large l-shaped body mount towers that came with the kit. I ended up going narrower than I could have got away with on the front cuts. I chopped the DT-03 suspension mount in the centre to get the front of the shell on and off. Not bothered about the nth degree of wheel control and can always get the fancy TRF carbon one if I feel the need in future. After a couple of aborted attempts at orange from Tamiya and Halfords, and neither before strong enough for my liking and went for it with neon orange. Stickers are from MCI Racing, with red replaced with black, and yellow replaced with dark grey. Pretty pleased with how it came out. Another modern look I'm not keen on is the super short front overhang. I like the big 80s bull bars, so inspired by AMPRO Engineering on Youtube I knocked up a bull bar bumper in 3D CAD and got it 3D printed from Shapeways. Only cost a tenner! Sets the stance off nicely, I think. I do love the kit black star dish wheels though. As for the car, I loved building it and it seems solid. I've never had brushless before either, so I went for a 13.5R Speed Passion MMM motor from Modelsport who also did my some leads with tamiya plugs, and a steel 17t pinion and a bearing set to start with. The kit came with the CVA dampers with the fixed solid plates on top of the shafts. Initially I was a bit disappointed. I'm certainly no expert and have no plans to race, but it was very understeery and bottomed out a lot. Due to older equipment I have already, I still use ACOMS 27MHz radio and NiMH batteries to keep costs down which I've since learnt are on the heavy side, but they work fine in my Thunder Dragon! So, after going down the rabbit hole of what mods to do where, trying not to spend a fortune on hop ups and learning as I go, this I think is my basics for getting the DT-03 to somewhere near it's potential and also hopefully help some newbies looking at getting their DT-03 running nice in my opinion: 1) Junk the stock tyres. The deep rib fronts that come with the Racing Fighter in particular are useless on hard surfaces and I generally muck about in the street or at the yard at work. With the fiesty motor I started tearing through the rears too, and have ended up with Schumacher Mini Pin Yellows on the stock rims. Works great, and the yellows last longer than the blue counter-intuitively, because the blue is harder it span up too easily on hard surfaces and wore out. On things like the pump track in the pictures, the mini pins are immense. 2) Connected to 1 - Be honest about where you drive. Having burnt through cool looking buggy tyres I now have a second set of wheels (Schumacher Flexlite read, Tamiya Dish Front both in black) with Schumacher RT1s and medium inserts for tarmac. 3) Suspension - I'm using the DF03 (not a typo, the 4WD car) setting springs, hard rear, softest front. Both are firmer than the kit springs. The DT-03 settings springs were right out because the colours would have looked rubbish if I'd needed the red ones. Yes, I am enough of a tart for that. Plus, couldn't see the point of a softer set of springs if the kit springs were in the middle. I saw the DF03 springs suggested on a thread on here I think. Great call. I got the TRF 54043 piston rods for the rear shock and standard CVA mini shock shafts 50601 for the front and used the kit sprues and some e-clips to convert the dampers to proper pistons. After some experimentation I'm running single hole pistons with the kit Soft Tamiya 400 CST oil 4) I got the anti roll bars, but have ended up not using them. Now I have the suspension firm enough to hold the car up it handles fine without the anti roll bars. IMHO. 5) I used the leftover ball studs from the unused roll bars to replace as many of the step screws in the damper mounts as possible. Much nicer and less rattly I got a bag of ball connectors (50591) to finish the job off, although the fronts need a bit of filing to get them to fit the wishbones. 6) Turnbuckles - Don't be a cheapskate like me and pick up a cheap DT02 set, as the steering arms don't fit! These do seen good for getting the grip up though. 2-3 neg both ends. 7) Driveshafts - I had no issues with the toughness of the plastic driveshafts, but I couldn't believe how much they restrict suspension movement. I didn't want to spend out on Universals as I'm not racing. I ended up taking a leaf out of the Sand Viper book and went to the metal driveshaft and cups. Only cost about a tenner for the parts, and the car stands up at the rear about another 10mm! They look better too, IMHO. Parts are: Shafts - Tamiya 9805551 Outdrives - Tamiya 9804237 Hub end cups - Tamiya 50823 8) Geared diff with the kit seems fine. I stuffed it with grease as advised somewhere on the internet and does fine for me. 9) Kimborough servo saver was a fiver well spent. Much more crisp steering. 10) Not sure if the Hop Up servo mount was £18 well spent, but it looks pretty and does look into the chassis and servo much more firmly. I'm open on this one as it's pretty expensive. Hope you like it, and hope that helps anyone looking at getting a DT-03. Cheers!
So if you want to jump straight to the changes from buggy to truggy/truck and an explanation of sorts as to why jump straight to it here... ——— So as the title tells you I’m a total beginner at this so be gentle! I was unsure whether to do a build as I imagine it’ll be of little interest to the veterans, but maybe someone in my shoes at some point will come across it and find it of use. Here goes then. I’ve wanted an R/C on and off for years but never got round to it until now (is that a recurring adult theme?) It was a definite heart over head moment as I did virtually no research(!) and pretty much jumped straight in. I looked at a few RTR’s but beyond the ease of getting up and running and the possible initial reduced cost I wanted the build part. If I’m honest that’s the part that’s most appealing to me, at the minute at least. So from that I started looking at Tamiya kits and was initially looking at 4wd kits but then I came across @ThunderDragonCy build and was totally drawn in by the build and tweaks he had done and bit the bullet on a 2wd DT03 Racing Fighter. Thinking about it afterwards I feel that was the right choice. Although the 4wd kits are by the look of it more involved to build I feel they would be less fun in use, possibly too easy whereas the 2wd kits once built and running should be more fun/challenging to drive. Time will tell...plus I can buy a 4wd later! So to start I just bought the kit with the CVA shocks, ESC and Torque Tuned Motor, but nothing else beyond buying some bearings, although I did buy a couple more bits a few days later but I’ll detail those as they come up in the build. The plan is to research the rest, (servo/batteries/transmitter and receiver) as I go. I’m in no rush and at the moment have very limited time to build the car anyway (first clue for you all that this won’t be a quick build thread!) Nothing exciting at first but I’ll be sure to document any issues etc I come across as a novice builder and then later with use I’ll share any tweaks etc. And if you’ve made it this far, well done 😂 So then, to begin...
Hello all. Total newbie here who after years of wanting an RC and never getting around to it I have finally pulled the trigger on one. After reading @ThunderDragonCy build I decided to go with the DT-03 Racing fighter (preferred the body over the Neo). I had been looking at all sorts and a lot or RTR’s where coming up which would no doubt have been cheaper to start, but for me, I really wanted the build process from the start not just the strip/repair later on so started looking more at the Tamiya cars. Toyed with 4x4 because they looked more involved on the build, but decided 2WD would be a more sense initially just in case I don’t take to it all (plus I can get another 4x4 later 😂) So far I’ve only ordered the kit and some bearings so still need a fair bit before I can build it and run. I have a few of no doubt many questions for you all of you will. 1. Can you recommend a good ‘starter’ tool set? 2. What spares would be advisable to have handy? 3. Only glanced at the pdf manual so far but do you ‘have’ to paint the inside of the body shell? I haven’t decided on finish yet but had something in mind that would no doubt be tricky on the inside for someone like myself who has never done it before, but much easier on the outside. Looking forward to getting started, missus thinks I’m crackers (not much different to normal however!) Sorry for the long post and cheers for any help.
Hi Guys, I am looking at getting a buggy to build once I have completed the CC01 that is currently on its way to me. I need help with making the right choice. So I am asking for advice from all the awesome guys on these forums. I'm looking at the three chassis below, 1. Grasshopper 2. Holiday buggy or any of the other DT02 Chassis 3. Racing Fighter or any of the other DT03 Chassis Any advice would be greatly appreciated. If you guys have other options for buggies, I would like to know that too. Thanks guys.
