I would not screw the engine direct to the ply plate. The engine lugs are not a big enough surface to prevent then from "Bedding" in over time.

I would suggest a 3/32" or 1/8" thick aluminum plate about the same size as the ply plate for the engine to sit on.

My first Dust mount was laminated with 1/64 ply and glass cloth top and bottom near the mounting holes. There was minimal mount maintenance after 100+ flights with a Jett 50. It held up much better then I expected it to. You can see the engine is still mounted after the final flight.

I used kevlar mat top and bottom of the engine mount with Kwik poly insted of epoxy, it's fuel proof and very hard. There's .007 carbon under all the tri-stock and on the sides of the main ribs. the front is framed/skined top and bottom with 1/16 ply insted of balsa . The battrey is aft of the rear spar to balance the large engine and extra renforcement.

By the way, the latest plans call for the antenna tube moved aft of the front spar due to brakeage problems. If you add some ply to yours around the pass thru area it should be fine.
