Well, rather than start another thread, ill just post it in this one. I just recently upgraded firmware to 1.24 (beta) & am using castle link 3.220. I set motor timing on lowest, BEC voltage to 5.0v & there the only settings i changed. Took it for about a 10min run, came off hot motor, hot esc (remember fan dont work), but battery was fine.

Im running this in a slash, 58/12 32p gearing which is equiv to the stock 86/18 48p gearing, 4600kv motor. been running this gearing for quite a while with no probs apart from hot motor. I dont really want to go down another tooth on the pinion because the speed im getting is absolutely perfect.

I remember when i dl'd the CL 3.220 it said 'operating temps will be higher when using this version' or something along those lines. & i thought by lowering the motor timing, i thought that would have also prevented a little motor heat, im puzzled on this one....
