I left for 2 weeks vacation on July 19, so I saw the model for the first time yesterday, and only had a brief look through as I had to fly out again today to Reading PA for the week to install a packaging line. But.. the fuse looks really nice, light layup but seems plenty tough enough for the job, tail surfaces look good, sheeted wing panels look good - I like what I see so far! That's all I can offer for detail at the moment. I did suss out the side mount versus inverted idea by holding the engine up to the fuselage and going "hmmmm.." and I think side mount is the way to go, the header would need a moderate amount of offset for inverted. Jury is out until I take a good look at the pipe length, header length needed and the resulting geometry.
