I fly real planes as well as RC also and found the transition fairly easy. I remember my flight instructor telling me over and over "Throttle is altitude and elevator is attitude". So in a real plane you always increases throttle to gain altitude, you do not pull back on the elevator. So left stick is throttle and moving it forward increases altitude both on drones and real planes. The right stick on a quad is exactly the same as the joystick on a plane, pitch and roll. The only issue with drones is that the right stick is being used for forward motion, and it is a bit different, but in reality it does cause the drone to pitch forward and thus increase speed. I had the same concerns 4 months ago when I first flew a drone but found it really easy to transition. The fact that these drones just sit and hover in place when you release the sticks make them extremely easy to fly.
