I started out geared at 10:1 (same race as drewdc90) and went up and up - eventually to 8.9:1 with no heat issues and better performance each step up in gearing. Track wasn't that big either. It was a much higher ratio than I expected to be able to run.

Hey guys I am in the process of switching my GTX to the GTB. Which setting should I set on the GTB for brushed motor racing? I am used to running profile 3 on the GTX, are there any similar profile on the GTB?

The brushed mode in the GTB is the same as profile 3 in the GTX

Default Thermal cut off

I've tried to read the previous messages about this subject, but I did'nt found the right information.
What is the solution to solve motor thermal cut off?
- using a cooling fan?
- changing gear ratio?
- playing with EPA?

Last week-end I used a cooling fan and a heatsink on the motor with no second, I just could a few more seconds...

Thanks for your answers

Use the the correct gearing...

The only times my GTB has thermally (or the motor incidentally) is when i've geared it too ambitiously.. or when the fan on the esc has died...

Just follow the recommended gearing.

I used to run mine too low, to compensate for my very old and ordinary battery packs. Thermally at the end of each run but got up to a reasonable speed on the straight. GOt new batts, geared conservatively and wow.

Maybe because when you are racing there are no reverse allowed?

I heard a rumor that novak was thinking of making a motor closer to 27 turn stock speed.. Is there any truth to this?? I think it would be great..I run oval and i think it would be huge.. i think the spec classes would love it as well..Seems harder and harder to find a good spec motor..

I know for a fact that they have been testing such a motor. I'm not sure how this will help though since it will be near impossible to run these in stock even if the performance is the same. If we're going to create a new class why not just use the 4300 which is similar to a 19T?

Im more curious about a new stock class... I dont mind the speed of the 4300 class, but its faster and parts wear more.. I like stock because it is cheap and simple.. would be nice not to have to do motor maintinance..

Some guys cant really handle the speed either.. Like the spec guys or novice.. Take away having to do motor maintinance, and it makes it easier on them.. But they can still do the same speeds...

Could have 3 classes..

2700 clas (stock)
4300 replaces 19 turn
open class......

There needs to be a slow motor for the novice racers to run. Not everyone is going to be able to pick up a transmitter and tame a car that's the speed of a 19 turn motor.

All of the guys that want to run faster than stock can just run a faster class.
