Ordered complete Sonex aircraft kit, with dual stick, tri-gear and AeroVee engine options. Still undecided on which engine to use though. I am kind of leery of the AeroVee, I have talked to several Sonex owners, and they say this engine lacks sufficient power to climb when the Sonex is at or near max weight. Building the AeroVee engine would be fun though. I built all of my stock car engines except for one, and it was the only one to self destruct.
