Ugly Stck goes in and don't know why??
I was at my local field the other day and was in the middle of my third flight when I lost radio input? It started flying away nice and level. I backed off on the throttle and nothing just kept flying away at half throttle. No up,down,left or right input worked. So I shut off the transmitter and turned it back on it went to wide open throttle and banked over to the right and went in full bore from about 200' up. I was bummed but I was also relieved that it didn't fly away and damage or hurt/kill someone. I have no idea what went wrong. The batterys where just cycled a couple flights prior and good. Had a full charge on both transmitter and receiver . I was able to recover the important parts. The receiver battery still shows a full charge. I cleaned the motor up and fired it up no damage. It was not spread spec it was 72mhz. Any ideas ??? Because I'm at a loss as to what happened...
