I was fortunate to pick up a sweet Kaos from a buddy at the field who felt the Kaos was way beyond his abilities. He wanted a nice used Saito 82 that I had, so we made the trade which was a steal for me. Looks like a scratch built Kaos, with an Enya 60, and in tail dragger configuration. Flies great as you all know, like on rails, but it looks about as thin as a pencil when flying by low and fast with wheels up! I have had some probs with the retracts location causing the plane to nose over on landings in the grass. I have shimmed the back edge of the LG mounts so as to move the wheels forward when down. So far the shims are about 1/8" thick! If the prob continues, I might have to put on larger wheels which will require enlargement of the wheel wells, an idea and task I am not thrilled about. Whoever did the original build must have flown from a runway other than grass.
