you should not gear it that low, your fast burning the brush. it may be fast but the motor will get damaged like burned after 5 minutes. I've race using rz and never geared mine that low.

Dude, no one gears that low even on super big track. Ideal for your track at Wltermart is aroung 6.1-6.4 only. Conditions was dusty and traction is poor so its useless to gear too high bro.

N4S, u might want to check if HPC could bring them in since they used to bring in atlas motors. I got mine from Champ. My level?...not a big difference...just ego boosting perhaps They'll eat your comm like nobody's business tho

FSR yeepp! There's none actually the best ratio for a particular track...since our driving approaches are different. And i haven't been to that track for ages...they've re-surfaced it twice already! Start with about 5.8 and see if u can keep up with the rest. Else...pm/sms those faster guys

BTW, why rpm-based motor for that track? Lotsa turns...ya need torque-based stuffs over there imo

I put the motor on a robitronics dyno and got some good torque and power numbers but low RPM. Something like 205Nmm and 160W @26000RPM. Does this low an RPM sound normal for this motor? It is brand new with only a couple of minutes break in time.
Sorry,we at asia is running the motor in touring car and we use rubber tire.for rollout,i had no idea,sorry mate.

It's not that easy...

Google translation:

15-4-16 motor
The carbon brush holder stand rise (vertical type) only those of type, variable advanced angle is recognized.

Seems only standup brush allow for change timing.
