Dynam Smart Trainer Problem
I have one of the Dynam Smart Trainer airplanes. When I flew it everything was fine, until about 4 or 5 minutes into the flight, it started to lose power. I had to give it full throttle to try to land it. In the process the motor stopped and I had to dead stick land it. I then checked the battery (4 cell LiPo 4000 mAH) and it still had 60% remaining. Any idea what the problem is?
