In FBW mode, the APM turns almost any plane into a perfect trainer. My two older daughters (9 and 7) were able to confidently circle over the Berkeley marina. Despite the 10-15 knot winds the Bixler2 behaved very docile and controllable. I had them completely ignore throttle and only focus only on the aileron.
I was amazed on how stress-free the flights turned out. After a few minutes of practice I felt confident enough to stop watching the plane and take some pictures of the young pilots.
Besides getting cold from the wind they enjoyed it and want to come back out to the field with me. I'm thinking to let them practice a few times in FBW (to get used of the correction when the plane flies against you) and eventually graduate them to stabilized mode.
