Hi guys, I have just finished major heart surgery on my P2V as I transferred all the insides onto a Tarot 650 frame. The swap went pretty smooth, everything fitted neatly and the only thing that was irreversible was that I soldered longer wires from the ESC's to the motors. Went to power it up though and it does the usual boot up sound but there is another loud beep over top then a slightly quieter beep beep beep beep which is constant. The main rear lights are flashing constant fast yellow and the little led on the circuit board is flashing alternative red and green. The motors won't start by putting the joysticks down but it connects fine to the mobile app and I can see the camera view. I can connect via USB to PC and no errors show up, it even updated some of the firmware but still all I get is the constant beeping. Any ideas guys?
