Well here is my current setup...

TC3 body
rebuilt / relubed diffs
blue front springs / yellow rear 30weight oil in shocks
Foam tires
Mamba Max ESC
Mamba 7700kv motor...
2200mah lipo 2s 35C busrt battery (id like to get a 5,000mah battery soon)

Im running 72t spur and a 17t pinion... speed are in the 35 - 40mph... does this seem right? I was thinking of changing to a 20t pinion and see. the motor does not get that hot right now, 8+ mins running topspeed and still able to touch motor.



What sugguestions would u give for gearing for top speed?
I was thinking about getting the clip on heatsink from AE and coating it with thermal paste to increase heat transfer...

im running an 87 spur and a 28 pinion now on my hpi rs4 with a 3 cell 5400,its been taken that beating for over a year.I say try a few more teeth on the pinion.

I have 5700kv motor and use 85t spur and 25t pinion and 3s Lipo It runs kind of hot but I have the speed that I wanted, about 55mph. However my TC3 was nitro that I converted to electric. I think you should up your pinion gear may be 25t and see if you like it or not. Just keep on checking your temp.

SIRCC

where did you get info on converting your tc3

I didn't get it from anybody. I had to buy TC4 motor mount, and single speed TC3drive shatf (my TC3 nitro was a two speed), TC4 spure gear and did some drilling on my own. Let me know if you want some help.

One more thing. I just change the pinion gear to 30teeth and it run cooler then when I have 25teeth. Don't ask me why so. Now I can touch the motor longer than 3 second. My speed is about 65mph with 85t spure and 30t pinion using 3s 20c lipo.

that sounds better. it was undergeard mass. a 7700 on 2s in a road car
geared right, should go 60+ with ease.
