A friend of mine is building a "Boxer" pattern plane from plans with some modifications. Very nice so far. He is enlarging the fuselage to accomodate an OS-1.20 AX engine with a Mueller Header and a Tuned Pipe. He also is enlarging the fuselage by adding a bit more height to the rear of the fuselage, increasing the size of the horizontal and vertical stabs, and making the wing length equal to the fuselage length. Should be nice when he is done. He's a craftsman.
