對的, 因為低v數 = 高電流 = 高溫度

Power = Voltage x Current

For the same amount of power, if Voltage is low, then Current is high.
Opposite case: if Voltage is high, Current is low.

for the foam tire index: higer degree mean softer or harder

Higher# = harder

Try:
Rear tire diameter: 46mm
Spur: 96
Pinion: 22
This gives you rollout = 33mm  (3.1416*46*22/96)

If your esc and motor is not too hot (<60C) then you can gear higher.  
Note: For RS Pro, maybe try dual mode first.  then if temp is ok, then try sensored mode.

IC...thanks

Tomorrow I will try 6.6V + 5.5R ....  see you all @ JV!

Rollout 大d就快d係咪架

yes, rollout = motor turn 1 turn, car move forward X mm  eg.  roll out 33 = motor turn 1 turn, car move forward 33mm.
