50% plane I have the wing mfg A-26-B. I used the planking method to build my naicels and have TT 40 for the power. She fly like she is on rails.She is about five years old and stil flying great. I done her in monokote chrome with warbird stars and bars. She has bomb-bay doors and some times I will drop orange or blue chauk line chauk from them. The TT-40 weight about the same as an OS 25 or 30 but are forty size. Mine are very reliable out of all the flights that I have had I have only had about two or three engine out situations [X(] This plane does like to land hot( trust me do not try to float this bird in fly it to the ground and then throttle back) learn this the hard way but only broke the wing bolts and wing plates out of the fuse. Be sure to have the nose of the plane level with the wings. Otherwise you will have a very interesting maiden flight.
