I have been flying this plane for about 3 years now and have just crashed it for the final time. It flies ok and is a lot of fun but as noted earlier it isn't a 3D plane. It will do most of the manouvers but it likes more speed and that is why I liked it. Mine was nose heavy with the 46FX but not bad. It like most biplanes would like a 4stroker engine to overcome the extra drag. Take a look at Ohio Model Planes at the Boxer biplane it is a 3D plane and about the same size.
