Hey gang. What size TC bodies fit these things? I am assuming 190mm, but I want to be sure. If it fits 200mm, I have a wicked idea for a spec racing class.

Sure you can mount a 200mm body shell but with the wheel arches way broader than the wheels,you'll have one wierd looking car...

I run GRP 38R 40F
Car doesn't like foams if too large so you need to true the fronts down to half original size, also true both ends with 1º positive camber (yes positve +) else you'll spend 8-10 laps with a very loose car.

If you run foams you will notice that they wear more on the outer edges, so putting +1º trues them closer to the shape that they will eventually go to.

Just back from the track
It was damp so grip was s---, had to run the Pitz D20 rain tyres.
The gearing for the 13.5BL was way out, I went there with 20/104, and even the last run before a big downpour I was up to 35/64 which may still be ungergeared.
Someone could have told me that a BL has zero motor brake, I will have to remove the RX so the lead can be disconnected just so the ESC can be set up for some drag brake.

I run my F103GT ourdoor on Asphalt with Sorex 40Rs, Brushless 7.5R and 48 Pitch Gears. I never tried the stock or Tamiya 0.4 module gears at all because I know they don't last.
The choice of my body is Stratus 3.0. Will be changing over to Nemesis soon to see how it performs. Have used Stratus 3.0 for about 6 months (because I bought like 4 pieces at a go) and no problems in handling. The only thing I worry all the time is the overheating of my rubber tires.
Foams are easy to drive, but it's sluggish, to my feel. And it's hard to determine the ride height.

I tried the 35 but it got very very hot on the dry track, but on a damp track I still use the 35 to reduce wheelspin.
I have ordered the newer 3racing motor mount with the cooling fan, as mine is the older type with no fan, hopefully this will allow me to use the taller gearing.
(track has a 155ft slight uphill main straight)
(200mm Nitro Touring cars often reach 50-58mph on this straight)

Only because with a 32 on a hot day I got it to thermal shut down twice after 5 minutes (using Courage shell).

Both pitches aren't the same. You may run it with no problem now, but after a short while, either the spur or the pinion will start to give way. Listen for the noise caused by the meshing of the gears.
0.4 is in METRIC and 64 is in INCHES.
Even the 48 pitch gears are now available in both Metric & Inches too.

I've gotten my new 8.5R PRO Motor and run it at 15T/82T. No thermal at all.
The stock gearing ratio is at 5.00 (70T/14T). Are you serious that you are running your gear ratio at 2.97?? Do you get any thermal with that low gear ratio?
