Cool, but be careful Nic... The engine mount transfers stress to the
central tunnel. Hanging 160# out front on a leverage arm is one
thing. Pull 3.8G per U.S. standard, add 50% for mom and the kids, or
double/triple it if you like doin' acro, and a first-year engineering
student can show you many thousands of # stress on a cheap scientific
calculator. Traditional engine mounts attach to fuselage sides, and
e.g. in the Lancair, there's reinforcing carbon fiber hat sections
there to spread the load. I chopped and narrowed my (tri-gear) tunnel
down a bit, but conservatively so, and reinforced with uni-cloth
strips at the engineer's 45-deg triangle I read about, since the only
engineer I know drove choo-choo trains. Somebody's gotta do first
flight soon in N3EU, and no waiting list yet beyond me!
