Had one years ago with OS .50. Plane was very snap happy. Also, if I remember correctly, the landing gear mounts in the wing were very weak. Just a couple of small pieces of ply glued to the foam cores with no support. The gear itself was very soft too and would bend even on the good landings.
On the plus side, it goes together easy and fliew quite well as long as you did not over control the elevator or slow it down too much. I had many flights on mine before the radio quite working on me one day. I glassed the inside and outside of the wooden cowl and painted it. It held up just fine. cbk
