Hi everyone. Just when I thought I had my Piccolo FUN figured out, it stared spinning uncontrollably counter-clockwise at throttle over 30%. I have a Piccoloboard Plus and a headinglock module on a Piccolo FUN modified with a titanium shaft and metal bushings. The problem goes away when I fully recharge the battery, but comes back within a minute of flight. I can't lift it off or even control it in this manner, it will spin even with full tail throttle. Do I need a new battery? Do I need a new tail rotor motor? Any help would be greatly appreciated!
