1512 2.5D vs 3D on 5S?

yea i just ran a 2.5d on 5s 4000 geard for 39mph and it never got over 143 with my mm never breaking 95, and it was 70 outside. id do like edumakated suggested and check your bearings and connections and also set your timing on your controller to low or lowest, and set your start power to medium or low which ever works best. these will help lower the motor temp.
