To use AILEVATOR mix on the 9C you have to plug the elevator servos into channel 2 and channel 8

Then set the AILEVATOR mix from INH to ACT (inhibited to active)

Set the AIL3 and AIL3 percentages to 0

Set ELE2 and ELE1 to 100

Set ELE1 and ELE2 to +100 The positive and negative values change the direction so play with those till they are going the right way or leave it at the default values of +100 and -100 and use the reverse function on channel2 or channel 8
