I'm asking because since I switched to lipo my esc has gone into thermal shut down a couple times.
Man that is such a tuff Q. What ESC.? There are so many variables.
Gearing to low and or gearing to high will cause an increase in temp. Its a matter of finding that sweet spot. 1 tooth higher can cause dramatic heat increase and 1 tooth lower will be less heat increase. It usually takes more than 1 tooth gearing down to cause the temp to sky rocket.
If your geared to low and on the throttle a lot, it would be the only thing I can think of on being geared to low causing it to thermal.
When I run 5.5 or faster with the sintered rotor I would thermal the ESC. And my battery would temp 106.
Also keep in mind running your ESC for those 10, 15, and 20 minute runs could be some of that. I don't think they were really designed for that kind of run time. Are you using a fan.?
Long run times require some charm as for gearing.
