Bill, my advice is to turn off the "Safe" crash avoidance system or whatever they call it now. (used to be called "ACT" on the Hobbyzone Cub) If you already fly rc helicopters and/or doing fine on the simulator, the crash avoidance system will cause you more problems than it solves because it overrides your inputs. This is fine if you are 50 feet high and don't know how to recover from a stall or a dive. But if you are making abrupt inputs to avoid trees or other issues like wind gusts, the crash avoidance system can actually make things worse. Just my opinion, but I've got a lot of hours teaching kids with this plane.
