Thanks guys,
I have studied them pretty closely now. Amazing little planes, and quite small. They are more like a British MG or a little Porsche Speedster. Light, very small, very narrow wingspan, very fast. The orange one cruises at 180 MPH and maxes out at 200 MPH. Very quick little birds, but they land fast too. They do not have wings set up for slow speeds, so touch down is at 65 MPH with full flaps, which still isnt too bad.
In this set, the blue one is powered by a less powerful engine, and is similar to the British version Ajep production plane, but not a true copy. This is a W8 (blue one) with a Ajep rudder. Many people made the raked back rudder as it was a bit stylish.
Standard wings are wood ribs covered with a rare Japanese multi layer plywood skin, sealed up with no access panels, no rivets, no panel lines. Ultra smooth. Some people have or are making them with aluminum wings with wing tanks. The real Tailwinds have the tank under the panel similar to early Cessna's, Pipers, and the like. (Makes balance a bit easier, but reduces fuel capacity and area).
