DJI Mini 4 Pro drone repairs

We open the battery, measure each cell and check the protection board. If the cells are above the safe threshold we bring them up slowly and wake the battery so it charges normally again. If a cell has dropped too low to be safe, we tell you, because that battery should not go back into service.

We inspect the airframe, motors, gimbal and sensors of your DJI Mini 4 Pro, read the flight and error logs, and run the motors and gimbal on the bench. You get a clear list of what is damaged and what it takes to fix. Diagnosis is free when you go on to book a repair, so this paid check is for when you want the findings on their own.

We check the dampers, the gimbal arms, the motor bearings and the ribbon cable, and look for bent parts or debris. Worn dampers are replaced, bent arms are straightened or replaced and the gimbal is recalibrated. Your DJI Mini 4 Pro is then bench tested with the camera recording to confirm the picture is steady.

We remove the damaged arm, route the new motor wiring through the replacement arm and connect it to the ESC board, then fit the arm and check the fold and lock. Your DJI Mini 4 Pro is bench tested with all motors running and the drone is calibrated before it goes back.

We remove the damaged surround, check the dampers and the gimbal mount behind it, and fit a new surround. Your DJI Mini 4 Pro is checked to confirm the gimbal moves freely through its full range.

We remove the damaged assembly, check the ribbon cable and the connector on the main board, and fit a complete new gimbal and camera unit. It is calibrated and your DJI Mini 4 Pro is bench tested with the camera recording before it goes back.
