Ok thanks for the feedback everyone. I’ll stick with the three channel stock version and see how it goes. I’ve been reading in several posts that undercamber wings don’t benefit from ailerons as much so generally not worth the hassle.It’s surprisingly maneuverable as a 3 channel, and I don’t really miss ailerons. The motor/battery setup you listed is perfect! I’d use a 2s for training your dad though. I used the 6x4.5 prop they recommended. It works well for me, so I haven’t tried any others yet.
