If you want to do flapperons ( in the future) you will need a seperate channel & servo for each aileron. I use flapperons on most all of my fun fly models & even on my Avistar trainer. However, you probably wont want to mess with them while you are learning to fly....Gene

PS, im useing Futaba 3004 servos in my fun fly planes & my trainer & they are not didigital & only cost $12 thru Tower. You dont need to spend alot of money at the stage you are at on servos.
