I built this plane not long ago and it flies great. I would suggest putting in two aileron servos as i did in mine. I made hatches between the ribs and it works great. The plane does tend to land fast with a 2 stroke but with the mixing i can used on my radio I can mix the two ailerons to an airbrake. This slows the plane down really well and makes it rock steady. I have an OS 46 in the nose and it hauls the plane around. Mine will knife edge ok but it tucks to the belly some. If you try a flat spin make sure it's HIGH because the four star take a long time to get out. Mine takes 3 rotations and full opposite rudder. If you fly off of grass I would suggest using nylon bolts on the landing gear. Otherwise the plane is really easy to put together.
