I have been asked by a number of viewers about brushless motor mounts for the Syma X8 so I went ahead and designed one up. Now I had to do a little give and take in the design to make it somewhat generic for various brushless motors so you might need to clean up some stuff inside with an Exacto knife however all in seems to work. I am also going to do two versions, one with mounting holes and one without (so you can add your own). Also I would highly suggest using something like XTC-3D http://amzn.to/2rM5otK to harden the mount to handle the torque generated by these stronger motors.

Would run at least 2 shells and at least 40% infill for extra strength.
