Hi Wojtek, Some years ago, a local guy installed a Amt Olympus in a nomex-built F-15, (same size of P.Avonds kit) and it flew fine, (the acceleration and sound at take-off was amazing!) the only issue was the "heavy" feeling of the plane at the beginning of flight . Please post a flight report of the P-200 on the KC to us know how it flies and if the residual thrust is a issue too.

Regards, Enrique
