RE: Unexplained loss of control
I have seen what happened to you many times. Not only with 2.4 but 72 mhz also. There are so many things that could have happened. The reciever could have over heated ( what was the temp?) and was the reciever wraped in foam. It also could have been the battery, I have been seeing more battery problems in the last couple of years. It only takes one time to over charge a battery and it is fried. I would send the reciever back to Futaba, After a crash it is best to have your electronics checked. Hopfully they will test it on a vibration plate set to 3-5 g's. This should tell you if you had a problem from vibration. Cheep insurance for a big money plane,
