My existing setup is:

1/10 TC class (HW ESC in blinky/no-timing mode) on a 25m x 14m indoor carpet track
SP V3.0 13.5 motor, with timing at the central position (is that 0° or 5°?)
FDR 4.9
Motor temp <70°C


I've just bought an MMM 13.5 motor, which has a standard timing range of 11° - 20°. I've set the timing at 11° to start with, but will I have to change the FDR to keep the motor temp <70°C? I've never changed the timing on the V3.0 13.5 from the standard central postion, so I'm unsure how much of an effect it has on motor performance & temperature.

Thanks
For V3, definitely max it to 10° (full right)...gear at 4.5~4.8 (depends on size of track).

For MMM (lucky you)....definitely try 15° and 20° max...but then, gear to 4.8~5.2 or so....

Rule of thumb....check temp of the motor after 5 laps, not minutes...mount FAN on motor heatsink if possible.

Play with the timing on the motor, it made night and day different.
