ok so here is my question i want to move to 2.4ghz i have a 33% extra with a total of 10 servos, 2 for each aileron, 1 for each elev side 2 on the rudder 1 throttle and 1 choke servo. does that mean i need a 10 channel radio? can i do it with the 7C how would i do it with the 7C i would run out of spots on the RX right? can a power expander be added to a 2.4 system? do i have to match the servos on the ailerons and rudder? this is my first really big airplane and i am confused on the 2.4 setups. thanks oh all servos in the airplane are hitec 645mg
