RE: Great Planes Escapade .40 ARF
The Escapade is nice because it has an open cowl that allows easy engine changes. I have flown my Escapade with an OS 55AX (briefly), Norvel AX-40 (briefly). and Supertigre G51 for a long time with a MACs muffler. I should try my old Irvine 40 with the tuned muffler someday. Someday I might try one of my 4-strokes too, But for now I/ll keep the ST51 on it. It books.
