I broke the Gimbal arm and damaged one of the little motors on my P3P.  As far as I can tell, the camera is still okay.  I have a P3S that I don't fly any more.  Can the Gimbal arm, boards and motors from the P3S be installed on the P3P?  I already now that the ribbon cable is different, so I will need to change that too.  I just can't afford to buy new parts right now.

Sorry, it won't work. They have different operating systems. P3P is lightbridge and P3s is wifi.

Thanks, but I fear the repair costs would be more than the drone is worth.  The new I.D ruling by the FAA and the fact that I just bought a new DJI Mini 2 really makes the P3P obsolete.  I'd like to repair it myself if possible.  It still flies very well, just no camera.
