I'm setting up a u can do 46,and I'm using an fma fortress rx with a JR 347 tx.I installed the plugs in the approiate spot i.e.bat.,throttle-1,aileron-2,elevator-3,rudder-4,gear on 5?,aux. on 6?,aux. on 7&8 also?
The problem I'm having is the split aileron servos.I should be able to use 2&6,right?But I'm having to slave 6 to 2 to get it to move with no trim on the slave aileron.?????????Whats wrong?Anyone!

well I use graupner/jr tx

the normal default setup is like that

1) throttle
2) aileron left
3)elevator
4) rudder
5) aileron right

if in your plane selection you called for a 2 aileron servo airplane it will work
