This mean seem stupid and like common sense to some, but for the five years i've owned the HobbyZone Sport Cub S 2, I have had trouble binding it to my DX6e. I realized how dumb I was after all these years. It binds perfectly fine everytime, as long as the battery is facing down and the plane isn't upside down. I hope this post can be found useful to anyone making the same mistake as me.
