Remember, at launch your plane is not at flying speed. It needs to gather speed first, then you can apply control gently (to climb or turn).

I suggest you use both gravity and the engine to gather flying speed. To do so, launch the plane toward the horizon or below, preferably below (so the plane is not angled up.) That way as the plane drops, gravity will help it gather speed. (If you launch it with an upward component, gravity will slow the plane.)

Then, do not apply elevator or try to turn until the plane is almost on the ground.... and then apply just enough elevator to get the plane level. When it has flown a few seconds level, you can gently apply some elevator to get altitude.

When you have altitude, you can try any maneuver you wish, but without altitude or flying speed, you have two strikes against you, and no room for errors in input.

Good luck!
