Hello everyone. Sorry if this has been asked a million times but I'm new to this site and am not sure where to start looking. ( I have tried). I'm after a 540 sized motor in 12V. But with more grunt than the one my 1/8 Formula 1 car has. Or if I put in an 8.4V battery and ran a something like tamiya sports tuned 540 would the electric, servos, etc. still work properly or would they be slower? Thanks all
