Will the 4 motors on the phantom 4 start after changing shells and not screwing the motors with the motor screws?? Meaning will i still be able to check ifmeverything is working before screwing the whole thing back together again?? And also does changing the board module 3in1 board part 52 with new landing gears fix my compass\topology error i used to have before??

Don't know about the last part, but you can check the motors without spinning them by listening to them beep or play the DJI tune at startup..

The tune play on all motors but they dont start in the app unfortunatetly, it says esc status error but can this be due to the fact i have not screwed the motors in the body??

Also used to say device topology error but ordered a new part 52 board module to fix this due to the fact i broken some cables on that board while changing the shell..

Anyone? Who knows about this??
