What could be cause of this crash?
Friend of mine was trying new build plane.
But immediately after lunch the plane rolls left and nose up.
The plane should have correct CG (its more nose heavy) and trims are neutral in first take of, on second take of ailerons are more to right turn. The plane is balanced in horizontal line (neither wing is heavier than the other one)
Im more into building than flying so i can not help him. But my guess is wrong motor angle?
Hand lunch was parallel to ground, motor can easily hover the plane. So power is not an issue
Thank you much for reply.
