This is a very capable airplane and it will slow down for a landing. I started with an HP .61 2 stroke and then mounted a Saito .80 4 stroke. A few hard landings weakened the wing center section. I fiberglassed the 12" center area and mounted internal hard points for a twin engine setup. I converted it to a twin with 2 Magnum .40 2 strokes. The fuel tanks are 8 oz. round with the bottom exposed. The APC 9.5 X 6 props just about touch the fuselage. I added a third .40 in the nose. I have about a hundred flights as a twin and I practice engine out situations without trouble.
