RE: 2.4 Satisfaction Poll
DX6 is fine with an Easy Glider. I have flown them way out on that radio with no problems. Besides, he was less than 1000 feet away, WELL within range.
Problem was not likely the radio system.
You had a new ESC? Why? That is where I would look. Overloaded BEC or not enough cooling air.
Has it always been flown on a 3 cell Lipo?
