When I was drilling the engine mount it was obvious that I have a problem. The back mounting screws had no material underneath them (due to me milling material incorrectly when I was trying to have the engine sitting low).
After a fair bit of coffee and spending time thinking what I should do to fix this, I decided to cast epoxy with fibreglass cloth pieces.
This worked quite well and the engine has been mounted satisfactory with the Nylon Insert Lock Nuts recessed into the balsa (the 5th elliptical hole is for engine tuning).

Next task is to fix the cowl "chin". I cut 4mm section and reinforced the mating area with two 2mm plywood pieces. These will hold the "chin" using 4-40 screws and blind nuts.
