Is USGT 17.5? If so I would not run the metal gears. They are perfectly fine in 17.5 stock. I raced the TBevo6 a fair bit and never had a failure, they have the same gears.

In that case, plastic all the way. Save the weight.

What FDR do you guys run for the Reedy fixed timing 21.5 in this car?

Parking Lot Track Setup
Here is the fully detailed car setup used for Tamiya TCS for a very bumpy mid grip asphalt parking lot track. Very similar to Cal Raceway, but more ride height for clearance and different gearing for spec 17.5 motor. I had to change gearing pretty high to avoid overheating as race day conditions were brutally hot. The spec dish wheels were not helping this car and my motor temp was 149F for the qualifiers and 155F for the race

How much slower would you estimate the car to be if you ran the Formula E body?

I have both bodies, and honestly, the FE is probably only equally matched the Gazoo on carpet tracks since the high grip removes rear downforce out of the equation. Im totally up for sharing if it means more people get into the class. Theres been a slow growth in car count for TCS asphalt races

I initially tried to put the fan on the end of the motor but finally attached hanging down from the side rail blowing into the motor. Due to accident impacts, I moved it on top of the motor, but the airflow is not good there and body interference was a consideration.

I've built several Tamiya cars in the past (just finished a TA-08 that runs great). I just ordered the TC-01. I want to run it in my local 21.5t TC club race. I have a question around replacing the kit JIS screws with hex head screws. Do I need to tap the holes with a M3 tap first or are the plastics soft enough that I can just build it with stainless steel or ti hex head screws? If I were to build it with kit JIS screws, could I move over to stainless/ti/aluminum screws later? I presume that would be fine but I don't know if the kit JIS screws are a different diameter than typical M3? Thanks!

If you're going to go with machine thread screws, do it from the beginning.
If you're going to do anything with machine screws, get a thread forming tap. They're about $7. They save you both time, and stop you from stripping the screw holes. Thread forming taps don't remove plastic, they just push it aside. With a thread formed, when your screw bottoms out, you know it, instead of kinda getting a "squish" when it bottoms out.
If you decide to stick with the self tapping screws. Use a little grease on the threads, for the same reason you'd tap the hole for machine screws.
