One of the main things I seem to find with the DX7 is actually saving the results of your changes. Go back in and re-do everything according to the book then make sure you save your changes the way the DX7 manual says to.

In the case of all the regular input channels, throttle, rudder, elevators, ailerons, and with the ailerons you are using a Y cord, you should not need to do anything to those except perhaps expo and end points. With the flaps, you may not have saved it after doing the changes. As I said, re-check that, and make sure you save everything then see if it works as advertized.

And, remember to make sure that the flap connections are on the same side (ailerons are one inboard and one outboard on the serovs where flaps, one is inboard and the other is outboard). See the drawing. Different aileron settings will have them both either inboard or both outboard depending on your situation and how your servos are installed) where the flaps left may be inboard with right outboard, or vice versa, again depending on how you mount your servos.

The drawing is just an illustration to show the difference.. again.. it depends on how you mount your servos and the direction they rotate when activated.
