Well, I got the Wi-Fi module installed on my M1P. Was a real pain in the (you-know-what), but I got it done. Had to (gently) remove the LED window in order to access the area so I could re-route the ribbon cable and the antenna connections. Didn't have any conductive grease (the silver 'goop'), so I had to be careful when handling it, since I didn't remove what was already on there.
Your instructions helped, but could have been a LOT more detailed (like, maybe make a detailed video of it sometime), but weren't detailed ENOUGH.
Mine was removed by the former owner and the coaxial connectors were removed at the same time. I bought a new module that has the coaxial wires and one ribbon cable and now I have to see about removing either the bottom of the drone or one of the boards to gain access to where these connectors go to. Is there another video as to how to do that? Several of the hex screws are stripped to the point where my 5mm hex screwdriver don't remove them. Is there a fix for that (stripped screws)?
