I have owned a Sport Cub S for about 2 years now, but it has not seen a lot of flying. I went to open it to fix a prop shaft that I had bent, and in opening it, I discovered a thin, red cable that only had one connection point. Is this the antenna for controller binding? Also, whenever I try to connect a battery, the LED flashes blue-red once, and then only red without binding, and the motor immediately runs at full speed with no way of controlling it. The only thing I did to the electronics was unplugging the black and white cables that connect the motor to the main circuit board. Does anyone know what is causing this issue?
