that was actually the 1st thing i did... didn't do jack squat... i think that's because these motors are smooth vs the ribber for his pleasure traxxas motors.
I then tried the dual fan clip on and that works VERY well, but the unevenness of the temperature on the motor had me concerned. I know...
So after bashing on just 2 sets of dual 3S's i was made aware of HOW HOT these motors can be. Long story short i tried a few things and they all kinda worked but felt they were lacking. I'm sure this is OVERKILL but i could NOT find anything that came close to cooling the entire motor with out...
