hmmm thanks for the advice, i read what other people run theyre zx5's on on other forums and to be honest not that many use brushless.
Iv had to replace one 5.5 due to reliability and really want this one to have an easier life rather than experimenting again with some many different pinion variations.. i.e runf for 5 mins - hmmm to hot , go down 1 size etc.
by changing the spur gear, will that affect the ratio that much?
Also by running the pinion so small, in thoery will i be doing more harm than good as in the motor will be reaching its max speed on all the straights rather than making the motor work more in accelerating and only reaching full speed on the large straights etc.
The track that i run are southport and bury - southport can have a few long straights etc. so hence the concern on the motor revving out etc.
Col.
