Once inverted, does it start to roll back? The whole plane (wing) provides lift, so if one of the wings has a difference in thickness or structure, that could influence its flight pattern. Try to trim the controls, change the elevation to the side that rolls.
What do you mean by automatically? Does it flip over as soon as it gets airborne, or does it roll one way constantly? Try and describe step by step exactly what happens
when i do a hand launch and level it out it automatically flies inverted and just levels out, im just getting into the hobby so i know that
im not doing it on purpose.
Hand launching does have a tendency to roll the plane. So right after you toss the plane you have to quickly get on the sticks and roll back upright and level. It's tricky at first, especially when you haven't been in the air enough to trim out the plane.
