Hello,

i'm still having problems gearing the Mamba Max 5700kv for the DB01.

2 weeks ago (midday, 32°C) with 17pinion and 91spur gear:
- after 7minutes of racing the motor was 75°C and the esc 65°C
- after 25minutes of racing the motor was 91°C and the esc 75°C.

Yesterday night (10pm, 23°C):
- with 16pinion and 91spur gear:
after 10minutes of racing the motor was 64°C and the esc 52°C;
after 20minutes of racing the motor was 81°C and the esc 62°C.
- with 15pinion and 91spur gear:
after 10minutes of racing the motor was 80°C and the esc 51°C;
after 20minutes of racing the motor was 81°C and the esc 53°C.

I cannot make the motor run cooler than this.

Do you have any idea what else can i try? Should i try a bigger pinion? Or a smaller one?
If i try a smaller pinion i might run it too undergeared.

I'm worried that even if I stay with the 15 or 16 pinion and go racing on a hot day, i will get much higher temps.

Thanks.
Mattia.
