I have two of these TX and both had the same problem with the trainer switch.... On the master controller you have to hold the momentary switch for you to have control and let it go for the student to have control........ Is this the case with all of the versions?? I have yet to see it on any reviews... I opened up the case and the switch has 3 tabs on it so I assume that they just soldered onto the Normally closed when the should have it on the open, vs. vers. not sure which yet but at least it will be a very easy fix. I really like their trainer features of this TX but sure didn't want to have to hold the switch to take it back from the student....
Has anyone had success using this without having to rewire the switch?? Am I doing something wrong? For now I am swapping the leads on the switch to get mine working as I have a 7 and a 5 year old and want to be able to let them have the controls a little bit at a time..... It's awesome how you can hand over just the rudder, or whatever you want one at a time, some at a a time or all at once....
With the switch flipped it will be perfect for my needs....
