After flying Apprentice with SAFE technology, for over a year, yesterday i nosed it into ground at 60 degree angle. I was shocked, I totally lost all control and it happened so fast I didn't use the panic button. Not sure it would of helped in this situation. It is repairable but now I'm concerned of issues with the signal or electronics. I was only 50 yards away from plane when it came down. Still in shock and looking for answers. I have a DX5 transmitter that came with this plane and have had no problems until now. No answers at this time.
