Hi,
I went out to my flying field yesterday with my Hangar 9 Extra Easy trainer. I was sure that I was ready to fly and everything was set up properly and the batteries were fully charged. I turned on my JR421 72mhz ch36 radio and then the plane's JR R600 receiver. When I checked the controls, the throtle, elevator and rudder worked fine. When I tried the ailerons I moved the stick to the right and the right aileron moved up, when I moved to neutral both ailerons began to cycle up and down on their own for about 4-5 seconds! I turned everthing off and then back on and the ailerons were showing eratic movements on their own. The single servo controling the ailerons is a JR 537. I am not sure of what the cause of this problem is. After I returned home I changed the servo and cannot duplicate the problem. I wonder if I have a receiver or radio problem. My flying field is very close to a medical building and I wonder if it was caused by interference.
