thanks.

What type of servo is better suited for the TT02? A low profile servo or a standard size servo and why?? Thanks for the advice

Both are perfectly adequate.
The advantage of the low profile servo is that it will allow you more room and freedom to use whatever esc you choose and mount it low, directly on the chassis, along with the receiver.

Finding some Tamiya parts can be a challenge. Sometimes the parts are a 5 digit number and are easy to find/purchase. Other times they are a 7 digit number and can be found/purchased directly from Tamiya. Often you can find the parts listed for a model at the very end of the instruction manual that came with your car. Sometimes these parts may be listed with Japanese words which can make it more challenging for speakers of other languages.

When I'm having difficulty finding a Tamiya part for one of my cars, I will find the particular model on the TamiyaUsa.com website. When viewing that model you can select the option for spare parts or option parts and usually can find most everything available for the car. Although it can be hit or miss trying to find/buy the individual lettered metal parts bags.

Another good resource for finding parts for Tamiya cars is the tamiyabase.com website. I just used this website to look up the Tamiya TT02 R kit. From there I was able to determine that the black plastic wheel appears to be Tamiya Part# 9335728 or 19335728. I then went back to TamiyaUSA and typed that number into the search box on that website. Those particular plastic wheels(rims) appear to be available directly from TamiyaUSA. Here is a link...

You can also trying searching through the Tamiya spare part section of their website, but I find that it can be time consuming for me. Maybe there is an easier way to find the 7 digit spares that only come with a few kits. I would be interested to hear if someone has any easier way to find those parts.

Either way, hope this information helps.

thank you for the very helpful information.

If you go with a low profile motor you can fit a ridiculous motor in there. Other wise it at least helps with getting the esc where you want it and/or not having all your electronics nearly touching each other.

Quick question: can I mount the front body posts on the front bumper stay. It looks like there is a spot for body posts on the bumper stay.
​​​​ There appears to be two different mounting locations on the wrx sti body up front. Is this allowed on the tamiya TCS series races? I've read the rules and to me them seem vague. First it says the car must be built per the instruction manual. Then the next sentence states the basic design can't be altered. So I'm alittle confused on if the location of the front body posts would be allowed. Thanks

I always use the bumper stay to mount my Subaru bodies. I don’t like having the body clips right at the hood scoop. You’ll need the body posts from a TA05/TB04 bumper sprue.

You can also use the rear bumper stay to mount your rear body posts. But that works mostly for bodies with a low rear, like sedans. The body posts won’t be long enough to use them for a hatchback body. Unless you get the Tamiya body post extensions

thanks. I know it can be done. My question is it legal to do in the tamiya TCS racing series?

Using the bumper mount body posts does not "alter the basic structure and design". Its perfectly legal.

My question is about TT02 Brushed Gearing. A few of us locally settled on TT02 Brushed Motor racing. Running Sport Tuned motors. I had 68/25 .6Mod gearing. I was not happy with the speed, so i bought a 64 spur with 27 and 29 pinions to try. The motor i have is only a month old with a dozen runs on it. I was running 68/25 just fine with no issues. Last night i tried the 64/27 and after a few short runs my motor died. Is that gearing too aggressive for a sport tuned motor? What would you do? reducing gearing ( perhaps 64/25)? or add a heatsink and fan?

As additional info we run run 3 minute races with a minute break in between. We'll run for about an hour at night and use 2 battery packs ( 5000mah). Finally last night after the car stopped working, i felt the motor and it didn't seem too hot. I wonder if it was jus excessive debris that killed my motor. Lots of dust and pollen out during spring.

What would you do?

Do you run nimh batteries or lipo batteries?

thanks

What type of battery is mostly used in the Spec/Novice class in the tamiya TCS series for the TT02 chassis (Nimh or Lipo)??

Lipo since it gives you voltage advantage, not to mention all the other advantages.
