fdr 10.17, did not try a higher gera, but didn't need to as the car was plenty fast.
Temp coming off track was 157 degrees

My settings were
7 on drag brake
1 on min drive
3 on the min brake setting
everything else is default.

If you go up a tooth and it's not any faster, go back down a tooth for your next race. The motors often have enough torque to overcome bad gearing, but it will cause them to heat up and use more battery.

Each of these endbells has a larger bearing in the front, which will allow you to use the newer rotors. You won’t be able to use your stock SS rotor, though. You’ll be able to ditch the brass shims which will quiet the motor down a lot. I recommend the sintered rotor, personally. I’m going to be using the ribbed endbell with the sintered rotor in my 4300. Here’s the two parts:

I'm beginning to feel skeptical about the tunability of these motors. The tuners keep saying "you just wait and see," insinuating that when there's enough interest, the tuners will get around to messing with these too. While we've seen that there's a few things you can tweak, nothing at all has provided significant results. Not to mention, the motors are so damn powerful, I'm not sure anything small matters like it does with brushed motors. I think I could replace my bearings with bushings in the 4300 and it wouldn't slow down.

How so Marcos? I looked at one at my LHS today and couldn't figure out how the fan would mount. I didn't see any screw holes . . .are teh gaps in the fins just the right size to alow M3 screws to catch and hold? Just looking for some clarification. Peace!

Tech Regular
I am looking for a brushless motor to run TC stock class. I also heard of a sintered rotor upgrade that will allow the motor to run cooler and "faster".
Does anyone know this setup?
Thanks

The setup you're hunting for is the Novak 13.5 motor with a GTB esc.
It is the MOST comparible motor to a regular brushed stock motor. I'm not saying that it is or isn't actually comparable. Different ppl say different things. But it is definately the closest thing they do.
Yes - this is nit picking. But someone will always want to chime in.
As for the sintered rotor - again a Novak product designed for their motors only. Improves the low down torque of the motor and is more resistant to high temps.
Check with your locla track to see what IS or ISN'T legal before buying!!
Hope that helps.
