I have had mine for about two months flying it in 2 jets have about 50 flights not a single problem. The only thing I found out is that when you use the transmitter with a pcm 9 channel receiver you need to move the servos from their original channel to the new layout of the 14mz where ailerons are no longer on channels 1 and 6 they have to be moved to channel 5 and 6 if not failsafe will not work properly.
