Phantom FX-61 FPV Layout

Phantom Motor Mount Repair

CLICK TO ENLARGE PHOTOS

Zeta Phantom FX-61 plastic motor mount is brittle and weak.  Mine broke on the first flight after a very gentle landing on grass and several other times.  JakeBullit gave me this nice tip.  Since the break left most of the mount "intact", I was able to place an aluminum disk and remount the motor.

More Repairs

Well, the disk worked well for awhile, but the root problem was still there...brittle, cheap plastic that breaks very easily.  So after breaking my third motor mount, here's my next effort:  

I got my plywood motor mount from my old Skywalker, cut out a notch in the foam behind the old plastic mount and glued the plywood to the foam and plastic.  Worked great!

The body of the mount broke this time.	Plywood Skywalker motor mount.	The CG will be effected somewhat, due to the wood and metal mount and positioning farther back.
