I have just bought a GP Cap 232 and am installing a Moki 1.8. I was wondering if there is a reason why I could not add an extra layer of ply to the firewall, and directly mount the engine to the firewall, with extended bolts going into the backing plate? I have seen this done on .60 size planes, and I can see it benefiting by dropping a few ounces of mount weight, but what might the cons be? Thank you, Mike.
