I just bought a new Bumblebee 550 from Hubbylord. This is my first multi-rotor and I am very excited to try it out. The problem is that during installation, I was unfortunate enough to connect a wrong connector to the main battery, which caused the MC-unit to be destroyed. Since I plan on building a bigger multi-rotor later, I decided to buy a Hoverfly Pro board instead of buying a new MC-unit from Hobbylord. The problem now is that when the Bumblebee`s electronics are connected to the Hoverfly Pro board, then the motors starts spinning in a given RPM and I am not able to control the speed at all. The engines start to spin when I connect the main battery and continues to spin until I disconnect the battery, regardless of whether I`m arming or disarming the board. The violet LED flashes too. Is there anyone here who knows what might be wrong? I have a suspicion that I have to reprogram the ESC `s, but I can`t find an English manual on Hobbylord`s 20A ESC`s anywhere. Grateful for any answers!
