Well...all i know after i gave them a call is that the whole plane is made from wood and balsa covered with film, one piece wing with adjustable and removable stab. The body of the plane had changed a bit which they moved canopy forward and reduce its size plus a little fin from the top. The main fin shape has changed and the whole body of the plane is some how narrower down a bit. The plane is not mass production, they made it to order...
