Had the phantom out Monday,Was not paying attention and hit a tree a long way out could not find it for 2 days. It got wet from the rain. Set in rice for 2 days and seemed fine. Flew for about 15 Minutes and happened to feel the motors and one seemed to be a little hotter than the others I clamped the Phantom down and ran the motors with props on for about 5 Minutes at high and low RPM Checked it with my Infrared Thermometer and it was about 2 degrees difference on one. I guess that is the only way to really check them. Because felt a lot hotter to the touch.
