Not surprisingly, the kit engine firewall is designed for the kit engine. Who'd a thunk it? :laugh:
It fits into a groove in the lower wing half and has a square hole where a square peg on the rear of the kit engine will fit.
The Engines & Things small Pratt I'm using has no square peg, but it does have a round length of aluminum tube I inserted down its throat for this very purpose.
To mount the engine to the firewall I pounded out a round of scrap styrene with the trusty Micro Mark punch, then drilled a hole in the middle that will accommodate a short length of aluminum tube one size bigger than that in the engine, and glued that to the back of the kit firewall.
Line everything up, and Viola! a nice sturdy installation. Cold beverages for the engineering department!
More later on the cockpit. The engineering department is still trying to figure out how to install beverage can cockpit sidewalls. Normally this would be a snap, but this thing has the cockpit nestled between the wings, totally separate from the fuselage sides. :S
