Try this on your DX 7

First, the rx connections:

1. right side Aileron into AIL channel
2. Left side aileron into AUX 2 channel
3. Flap into Flap channel (AUX 1)
4. Rudder, elevator and Throttle into the normal channels

TX program

1. Go into the Set-up mode (hold down scroll and select keys while turning on tx)
2. scroll to the Input Select screen
3. Set Aux2 to INH, AUX2 TRIM to INH, FLAP to SYSTEM (should be default) , FLAP TRIM to INH
This turns off AUX 2 channel from the lever.
4. do NOT activate Flapperon in wing type. This must be OFF.

Aileron Set up
1. Power off tx and turn back on. Go to normal programming mode
2. Scroll to P-mix 6. Set AILE as master and AUX2 as slave. Set the mix values to 100% in both stick directions.
3. Scroll to Sub Trim and set the neutral for the right side aileron with AILE channel and the neutral for the left side aileron with AUX2. (if the direction of one or both of the ailerons is backwards, first go to the REVERSING SW screen and reverse the apropriate channel (either 2, 7 or both)
4. Scroll to Travel Adjust. Set the desired travel for the right side aileron with the AILE adjustment.
5. Scroll back to P-Mix 6 and tweak the travel of the left side aileron to match the right side with the mix values by increasing or decreasing from 100%, for each stick direction.

Flap Set-up
1. Go to normal programming mode
2. Scroll to Sub Trim and set the neutral for the flaps with FLAP channel.
3. Scroll to FLAP SYS. screen. Set the desired travel for each of the 3 Flap switch positions. You can also set any elevator compensation for each of the 3 flap positions here. (typically it would be 0 for the neutral position and then tweak in what is needed after you test fly for the mid and full flap positions.)

That should do it.
