Late yesterday evening I delivered a set of twins, matching Great Planes Super Sportster 40 MKII ARFs. Here are a few pics of them posing together in my back yard. Both have had successful maiden flights and required very little trim in any axis. Both weigh exactly 5lbs. 5oz, with no added weight. One is powered by a TT.46Pro w/pitts muffler, and the other by an OS46FX w/standard muffler, each turning an 11x7MAS prop. 3 point landings are a breeze.
