I have a torment with a fuze 3800kv motor (still on nimh) and cannot make a spur gear last... The plastic ones strip... And my aluminum ones got all deformed and then stripped. Im am running a 17-24t 48p pinion and several 87t 48p spurs and I cannot get them to last.. I set the lash correctly (a thin piece of paper) and yet they still get messed up somehow... Any tips on how to get better life out of em? Is it better to go to a lower pitch? Any input is appreciated!
