I installed markamiles from backyard RC's motor mount(thing 128477) upside down so you can fit a DT750 inside. this makes gives youre motor a bumper for crashprotection.
Some sanding is needed to make this work but worth it!
If annyone could change the dimensions of the model it would be better.
with some cutting & sanding for turn clearance & wires you can fit a DT750 motor inside the motor mount. I also flipped the mountingplate of the motor so I could zipty it to the motor mount. I did put an extra m3 setscrew in the mountingplate to be sure my motor is secure.
very little turbulance considering the prop passes so close over the 12mm beam, fly 's nice!
