I bought my son an MCX BNF and was planning on binding it to my radio from my CX2. For some reason, the controls are bound backward. Lt is Rt and up is dwn?????? I am at a loss. The problem seems intermittent. Sometimes the directions are correct and the rotor/throttle control is backward. What the heck? Puts a new dimension in flying though. What am I doing wrong????

Thanks,
