Sorry to hear about the motor
I've got the same problem on my Maxi Swift. Going to purchase blockers on both ends to restrict the movement of the folding prop.
Now that the plane is grounded you've got some time to work on some of the more severe issues:
Get your VTx out to the wingtip!! No need for a 6dbi, use the stock 3dbi. Your VTx is almost next to the receiver and it blasts out 1W. No wonder you've got range issues
I use a 4 pole ethernet cable to run the wire out to the wingtips. It's twisted (= filtering) and shielded with aluminum foil and the ground wrapped around the twisted 4 poles. Check my videos in the "Show us your videos" for the range I'm getting. As your wing can handle the additional weight, I'd even recommend using separate cinch wires for audio and video.
Run the receiver antenna out the other end, you've got so much wingspan so use it!
