That is good thing about Spektrum radios you can't fly on the wrong plane. I have some on Spektrum and a couple still on a Futaba 6x. Only once i had the wrong plane both were yellow planes and I had one listed as yeller. I was having a guy help me with some stuff and he changed the plane from a Twist to yeller as he thought the twist was yellow. Thank goodness it just would not get off the ground and we figured out what was wrong before we tore a plane up. I have been flying for about well almost two yrs. and have in that little time seen probabaly 10 crashes because of radio glitches on various radios. But never on Spektrum. Did however have my neighbor over and we just could not get his Zenoha running right it wanted to run full speed and was at idle. The servo was twithcing like crazy. We changed it and same thing. Finally moved his ign. batt. away from reciver some and it stopped. So the Spektrum is glitchable i suppose. One of our trainer type guys crashed a big cub because of some failure just a couple days ago. Man nice plane he had also said it was no longer made so no need of even thinking of trying to repair.
