RJX SP Racing F3 EVO Flight Controller with PDB Power Distribution Board for FPV Racing Drone QAV R QAV 250 210 180 QAV X 210 250 130 ZMR 250

Seem to have a problem with the USB voltage leaking onto the PDB ( measured 3.5V at motor) stopping the calibration of the motors.Following the procedure for esc cal. the motors spin at full speed on connection of the flight battery.EDIT:Calibrated escs one at a time by connecting V+ on esc bullet connector, after usb was connected and in the esc cal. page.After an hour experimenting with the board orientation settings in Inav as the board/usb and orient arrow is facing backwards (the same way as the Battery connector) the board got hot and would not connect anymore.I now realise, as there are subtle differences like the baro on top compared with the sp racing manual that this is a CLONE. ( I didnt notice a previous comment stating this).Returning as a faulty CLONE

Everything you need in one comes with all the gear needed for mounting,mine came with betaflight on it,just needed to reflash to newest version.Plenty of people use the spf3,plus the benefit of the sd for blackbox,well worth the money and makes for a tidy build,keeping your esc connections in the corners,saves having the leads going separately to the FC board,and a built in buzzer,with the added bonus of including an ir diode for race timing,if you want to compete properly in races your going to need one of these,although it didn't come with the supposed to be include reg number,I'm sure you can still get hold of one.although I've fitted it,I haven't tried to register it yet.

Faulty gyro on board. Returned for a refund. Once bitten twice shy and and all that.
