RE: Futaba T7C 2.4GHz
I have a 7C so this shoulld work for you.
First , channel 6 is tied to the knob and channel 1 to ailerons. Go in the menu to flaperons and turn this feature on , then scroll down and set your second aileron to 5 , this should turn on your flap and both ailerons should be working. My radio requires a Y harness for to flap servos, to get around this you can plug your second flap into 7 , I used P-mix1 , scroll down and set the switch and position of this switch you would like to use. Scroll up and to the INH and turn the mix on. Scroll down and set the master to 6 and slave to 7 , scroll down till you see the rate % turn the knob to the right and change this to 100% turn the knob to the left and set to 100%, scroll down to OFS>SET and hold down your dial to set. This shoul get all four servos working , just change your plugs before hand. Every thing else can be handled through sub trim and servo reversing.
Good luck !!
