my favorite is my Super Tigre G-60 ABC/Ring engine from the late 70's/early 80's. It howls and it just keeps on a howlin'. What a sweet piece of Italian machine work. Sure wish I could find another one NIB.
I have a NIB G.60R, but I ain't letting go of it
. I'm waiting for the muse to strike and I'll build a plane just for that engine.
