The motor mount process we are using now is with 3"x3" piece of 1/16" ply instead of the supplied formica. The motor mount is mounted to the plywood using 1/8" 4-40 blind nut and two 4-40 metal screws.

Through the big hole of the motor mount is inserted a 1/4" nylon bolt through the drilled plywood and foam of the wing. The nut resides on the top of the wing with a load spreading washer of 1/16" plywood usually 1"x1". A piece of Extreme tape is taped across the bottom of the wing over the motor mount assembly to secure the lateral movement.

This is used to facilitate the easy on and off of the motor. We do not glue the motor mount assemblage to the wing anymore

Pictures will follow.
