I can hover now with my 3d foamy for about 5 seconds max. I just watched videos of hovering, and tried it about 50 feet in the air. Mostly, just come slowly forward, go back full elvator and get vertical, then use rudder and elvator and some throttle to stay vertical and still. Its pretty hard to learn, but im gonna keep trying. I learned to fly inverted, and do rolls and such with my flight sim
