Now is a good time to start practicing recoveries. Start with a stall recovery- point the nose of the plane up and cut the throttle. Learn to recognize when the stall is happening and push the elevator to get back to level flight before the plane drops its nose on its own. Then do the inverted recovery where you push the elevator and roll out (essentially the second half of a roll) then work through every odd attitude you might find the plane in- pointed toward you, away from you, going left and going right, then inverted in all those positions. Work out a procedure for the smoothest and fastest way to get back to straight and level flight headed upwind. Later when you advance to aerobatic planes, your stall recovery skill will become a spin recovery, and all the others will come in handy when you make a mistake and get into some funky position that you didn't intend. Also work on flying with your wings truly level. If you are at a height of around 20 meters, you should be able to see the underside of the wing that is toward you. You can verify that your wings are level by pulling into an upline. If the plane goes straight up or very slightly right due to p factor, you are good. Level wings are the basis of every aerobatic maneuver, and even if that doesn't interest you much it makes the plane so much more predictable. I'd say flying with the wings truly level is the single most important piloting skill in RC, because everything you can possibly do in a plane depends on it.
