Picked up a Hacker 21.5 and was told that I needed to turn the timing all the way up and then 1 more 'tick' to get top performance from the motor. Well, the little extra 'tick' gave me all the speed I was sorely lacking but now my motor temp was at 185 F when I checked it about 20-30 seconds after the end of the heat race.
Track temps were around 110-120f, air temps were about 105f, so the motors were starting out already warm. I do run a fan on the motor as well
1: What temp would be considered too hot?
2. Running a 5.5 fdr for our class, and I'm running a 113t spur and a 40t pinion (5.65 fdr). Would dropping down a tooth on the pinion be advised to reduce the temps, or are the 185 degree temps within a safe parameter?
Thanks in advance for your input.
