A 12/51 gearing is low, so it may help the motor out. Guys doing 10s systems are using 1400 kv motors and low gearing. Of course those are high end motors, but the same may be true for the feigao. We can all agree that an xl motor in a rustler would never get very hot, just not enough load on it. So relieving the motor with lower gearing may help the heat situation. Let us know what you find. I may try my 7xl on 5s(wow)! In a tower terror mt!!! 10lbs or less!
