Setting things up for the engine installation. I'm just using a common 20-25 size engine mount and it is about as big as can be fitted to the airframe without modifications. This model seems to be at that size where electric or fuel power are equally practical. There are aspects of the engine installation that are driven by my engine choice. With the two .25 engines I have on hand, ASP and Thunder Tiger, the exhaust would exit directly onto the wings leading edge if the engine was mounted in an upright position. This also has the added benefit of locating the carburetor closer to the centerline of the fuel tank. Since this model will get a nice vibratey engine I installed some triangle stock to reinforce the firewall. the installation isn't very elegant but it is done that way to avoid gluing wood over the engine mount blind nuts.
