First, I have 7CP with ACRO mode activated and in the plane i have 2 servos for ailerons (CH1 and CH6) FLAPERONS are ON and ailerons works OK
Flaps (FLAPTRIM) works OK too with VR6 knob.

I want to use flaps with switch but i can't get it work.
I made P.MIX1 OFST(master) CH6(slave) to switch G and RT50% but only CH6 servo moves (right wing)!
CH1 servo stays still (left wing).

How i get both flaps working with switch ?

With AIRBRAKE mix i get flaps to switch E but then i can't use AIRBRAKE.

please HELP !
