I'm running a 26t pinion and 68t spur. What should I aim for?
Those super stock motors can handle a lower FDR then mentioned on the box. I've run the TZ 23T super stock motor (witch i prefer more then the RZ) in my FF-03 PRO and went below 6.0 FDR but that was on a medium outdoor track. The FDR depends on how big the track is, but start a FDR arround 6.0 and go from there.
Cause the more wheelspin you have the less acceleration and more power is lost.
The trick is to find a perfect balance between acceleration and traction.
I've run this year my FF-03 PRO with a tamiya brushed GT Tuned motor against some 14T brushless motors (i was the only one who was using a brushed motor) and managed to finish 2nd overal.
A good car setup with the right FDR is the key to succes.
