Hi Max, I answered your email a few mins ago. I recommend trying 26pinion, that should bring your fdr to 3.77 if you still need more punch you can try what redbullfixx recommended (25-23pinion) please try one change at a time. Try changing the gearing first & test your timing change later.

When i tested the motor there was another guy with lrp x20 motor and flow esc. I was geared 98 spur and 29 pinion, on the straight my top end speed was a little bit faster than the otherguy, but on the exitof the chicane i was slower, it seems to me that the motor was lacking of punch.
Could you pls advise wich esc are you using? did you try to increase the timing (i know that 30° are factory build in)?

Tnks for your kind help.

Ciao
Max
