At times my MA2 won’t turn while it is going forward when I move the left joystick left or right. At times it also won’t stop its forward motion for a few seconds when I release the right joystick. And at times it won’t change its altitude when I move the left joystick forward or backward when the aircraft is moving forward. When the forward motion stops, then I can turn it or change the altitude using the left joystick. This happens when the aircraft is near the controller and when it is a long distance from the controller. There doesn’t seem to be any consistency in when it occurs. Is anyone else experiencing such behavior? Any ideas on the cause and how to fix it?
