Thanks for posting this Irish, I was thinking of doing it myself.

I'm the instructer Irish is talking about.

funny thing about this. I put a 2.4 RX into the club trainer and had a lot of trouble with it. When I give it to the student and the Ail. will work for a few min. and then slow down or quit. But if I take it back I have full control with my X9303 2.4 sys( Slave is a XF421ex 72 band). I have tested this at home and it repeats the problem, the Ail will work for about 5 min. and then fail, for the slave but the master works fine.

I have tried 3 servos into the wing, at present I have a new Hitec servo in the wing ( one serve).

I emailed Horizon about using the 2.4 tx as master with the 72 band tx as slave and they said this is alright. They said to leave the slave tx turned off with the battery in it, and that seems to be right.

Irish said that the 6v batter might run the Ail servo too fast, so I tried it with a 4.8v batter same problem.

At present I am putting the old Futaba trainer system back into the plane and see if that fixs it.

thanks for any help, I am really tired of this and the problem is not a good thing for the student. I know he has been having a problem over this as he is unsure of how and what he is doing.
