its pretty easy once you get used to it having a non-spring throttle, i would remove the ratchet though to give you more precise control, for controls,

left stick up and down = channel 3 which is your throttle
left stick left right = channel 4 which is rudder - this could be gear shift
right stick up and down = channel 2 elevator - this could be your gear shift
right stick left and right = channel 1 aileron this is your left/right steering

let us know how you get on
