I've built 5-6 of the Monocoupes, and even a clipped wing variant, and I used to fly a 1/4 scale 90a That I built from plans, heavily modified. I'm a sucker for the Monocoupes. I even located a copy of "Of Monocoupes and Men" By Underwood. On my HO scale layout I have the little Hallmark N101H , John McCullock's current 110 Special. I got a ride in Lil Butch before John donated it to the NASM. It's hanging at the Udvar-Hasey near Enola Gay.Sig's Monocoupe is a good, solid kit but a bit heavy. Enlarging it will help if you do some work to keep the weight down. The Monocoupe and Mr. Mulligan were kit versions of a couple of well known (40 years ago) contest winning designs. Easy Built has a nice big electric Monocoupe too.
