I'm opting for a
Valley Engineering V-twin with a PRSU and prop.
Total cost will be under 14K USD - I'm shooting for 12.5 but we all know what can happen there once tools and extras get thrown in to the final talley.
Haven't really kept track of man-hours, but I'll be pretty close to the 400 advertized I reckon....mostly because I do a lot of thinking and remeasuring when standing at the build table.
The big thing is that one really can build this plane in the space of a single car garage (or less) using standard hand tools (with a few exceptions that don't cost very much).
Bear in mind I'm staying within the plans! Modify beyond the purely cosmetic and the price and time can skyrocket.
I'm going to paint it in the French three color camouflage pattern, as dark aircraft show up better against the sky in the pattern and the roundels scream against the ground. Getting run over because my plane cruises at 60 MPH and stalls at 35 is a real concern.
