Hello everybody,

It is my first post on this forum, and my english is quite bad so i am sorry for my mistakes.


Few years ago i bought used Tamiya DT-02 Desert Gator buggy. I was using it just for fun, but decided to try racing this saturday. I started to replace broken and bad parts and decided to tune up my buggy to a PRO level (i am not sure is this possible).

What have i allready done:
1. Changed front shock tower to carbon http://cgi.ebay.com/3Racing-Graphite-Front-Shock-Tower-for-Tamiya-DT-02_W0QQitemZ390048579260QQcmdZViewItemQQptZRadio_C ontrol_Parts_Accessories?hash=item5ad0b4febc&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A1205%7C 240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50
2. Changed differential into ball diff http://www.rcmart.com/catalog/rc-dt02-tamiya-ball-diff-53863-p-16277.html?cPath=595_744_1220
3. Home made turnbuckles
4. Firebolt 15T motor, Novak T-4 ESC, MG995 servo, IB4600 batteries
5. Tamiya rear tires from Tamiya DT-01 (bought them at local rc store, but i don't feel good about them)
6. Aluminium oil shock absorbers http://www.rcmart.com/catalog/rc-damper-yeah-racing-alloy-100mm-buggy-dp0007bu-p-20086.html

What I plan to do:
1. Change all chassis to carbon fibre double deck
2. Change rear shock tower into carbon
3. Brushless setup
4. Good tyres


Could You give me some advices?
What thickness carbon should I use for double deck chassis and rear shock tower? Besides I have mould of original DT-02 chassis and i can make it myself out of aramid carbon or carbon fiber.
What bruskless setup should I use ( i plan to buy LRP SPX or Tekin RS, but have no idea what motor should I use)?
What good tires for this buggy I could use? Only I cuold found are http://www.rcmart.com/catalog/rc-road-3racing-buggy-spoke-tyre-dt02-wh21bl-p-28379.html

Here are some pictures of my buggy:

Sounds interesting.

the big issue is the gearing options on the DT02. You need to look at the gearbox to see if you can modify it to give you more pinion choices.

Also for the chassis. 2.5mm bottom deck and 2mm top deck is a good starting point. I'm sure others on here would have their own opinion.

dt-02 is very soft, need slipper and good gearbox with standard pinion module

i have dt-02ms - good "toy"
price is very similar to B4, but B4 is better :)

Thank You for some answers.

Pinion choice is very poor (17T or 19T) because of gear box, but I plan to rebuild it so I could use any pinion of that pitch. I saw 16-25T pinions for sale.

Besides electric offroad is new class in Lithuania, so PRO means a lot of power and carbon :D

How is your English bad? Many English people on this forum cannot write as well as that, and it is far better than my Lithuanian!

Hello again,

Well today I had my first offroad race. I was driving with my recent setup and the race was terrible for me. As the track surfaze was like tarmac (pressed clay) so my tires had absolutely no traction with the track. Before one race there was light rain and traction after that was much better.
Although this was my first offroad race I allready have some notices abot it:
1. It is impossible to drive 2wd car on track like this
2. Firebolt 15T is too much powerful (although I used only about 20% of power my buggy was drawing suns)
3. My tires were not for surface like this

4. I don't think it is worth to tune this buggy any more (I am thinking of buying PRO class 4wd buggy)


P.S. I finished 9th of 9 competitors...
