I have one. Although I haven't flown it yet, I have nothing bad to say about it. The plane is gorgeous, and the fiberglass fuselage is very nice and the overall quality is excellent. I have the YS FZ63 four stroke in the nose. I had the battery pack under the fuel tank initially, but it turned out too nose heavy, so I moved the battery pack back behind the servo tray to balance the plane. No additional lead was added. I replaced the stock fuel tank with a 12 oz unit. I'm also using Great Planes mechanical retracts.
