I'm using a new TX6I from OrangeRx. I'm thinking I might have got a dodgy receiver (also OrangeRx). This isn't the first time its needed major repairs. I folded the wings on the high start once. Yeah, I was pushing it too hard!
Good point! I will have to ask Hobbyking. I'm not certain, but I'm pretty sure I had the transmitter pointing in relatively the same direction the whole flight. This time and a few previous times I fly quite far away from myself (~600m or 2000ft), then turn around and it cuts out when I'm around half way home.
