I connected the Qbrain ESC, HobbyKing V3 multi-rotor control board and hobbyking 6ch receiver. This is the first time I have done this. I calibrated the ESC and tested if the motors were working just with the esc connected to throttle on the receiver and it seemed to work fine. But when I connect it to the control board I get a light on the receiver and a continuous beep noise, and when i turn up the throttle none of the motors turn. Please suggest what I should do to fix it. Please reply asap .THAnks!
