Please could some kind person help me. I had a small accident with my V2 Plus in that on take off it tilted and fried the speed control printed circuit board which I replaced including the motor. The problem now is that I have 2 solid red lights on the front of the copter indicating a calibration problem. I have up to 8 sats connected to my mobile but no matter how I try to calibrate they do not change. I have double checked the connection to the top shell and it is fine. The copter has been used for about an hour all told as we have not had much good weather since I bought the drone last December. I would appreciate any help as I am becoming a little desperate to try the drone out after spending more than a grand. Many thanks
