That book "The Lovable One Niner" is excellent and the pictures are awesome. My Dad flew L-19's in the Army starting back in 1954 and I bought him that book as a gift. I had a Vallencourt 108" L-19 powered by a Zenoah G38 until this last summer when I sold it.

I have also owned and flown the GSP 0-1/L-19. I powered mine with a Saito .72 four stroke. I'm interested in what you think of the quality of the plane and how it flies when you get to that point.
