On the first flight I had. Got everything tougher and did a radio check at the clear field and also with the engine running it was all ok. I was using my jr 10sxII heli radio so I thought i was ok as i used that radio with my other smaller nitro planes. So i was excited and nervous at my first gas sorry first big gas plane. went to take off and 15 seconds into the flight i was getting hard glitches i thought at first it was to high rates on the plane somehow i got it back 200 feet from me and lost it and went down and broke in to parts. it took me a month to rebuild it and the second flight had glitches again , but got it down and broke the landing support behind the firewall . Now i have 3 3mm laminated ply as a support for the landing gear and boy dose it hold , but heavy. So a friend was going to the states for two weeks and got him to bring back a jr 9303 plane radio and now it is perfect no more glitches. i think it was to the fact that i was using a hitec receiver with a jr radio and that the cap has very long servo leads . so that was the story of the damage due to radio problems.
