It wasn't feeling right and was occasionally having rudder issues. The rudder on occasion during flight was become erratic and spin on me. I ended up doing a hard landing because of it. I switched back to the stock remote and seems fine. I haven't taken it out for real flying, just hovering last night. Hopefully I can find out if it is the heli or the radio. I checked all my settings and can't find anything obvious that would cause it.</span>
