Motor mount

I wanted the motor to be removable so the supplied ply disc had to be modified to accept the M3 bolts from the wider motor mount.  I cut another disc with a diameter wide enough to take the mount.

I made some cutouts in the supplied disc to allow the outer bolt heads to sit flat.  The two discs were then expoxied together and the outer bolt holes were drilled.  Everything was then assembled tight to ensure alignment.

The bolt heads were then expoxied in.  The supplied inner disc still fits into the foam recess on the fuselage so it will locate centrally.
