using quark 125 monstor, which motor?

[Serum]

in an airplane the motor is on a constant load, and will get hotter because of that. It might run in a less efficient area from time to time on an MT, but still; 94% eff. at a 2500 watts load means a 150W heat and 88 percent eff. at a 700 watt load means 84 watts of heat. The monster (Mike) won several races with his Neu 1515 on 4S. My neigbour ran a 1512 on his revo on 4S and the motor was icecold.

I would advice you the neu for several reasons. The plettenberg is hard to get, it might look nice though.. But a fan isn't helping its efficiency either.

Rhylsader; i advice you to try a neu. you'll love them.
