RE: ParkZone P-51 Mustang RTF
These temps sound normal to me when compared to my other planes with DC motors and LiPos. If you are draining 1500 mah out of your LiPo into your motor, things are going to get warm. My motors almost are too hot to touch after flight, and the battery is very warm, but not too hot to touch. My vote is you are in the norm.
