Yes I started with the Mach 1. I always loved the way it flew.

1. I gave it more side area because I wanted better knife edge flight. That's also why I enlarged the rudder.
2. The Mach 1 always seemed to have some roll coupling. So I moved the rudder hinge line to a true vertical position.
3. I have had 2 Mach 1's over the years. One I built and one I bought already built. The one I built always seemed to run out of elevator at low speeds. So I have decided to give it an anhedral stab. Well I also think an anhedral stab will look cool too. LOL. Think Curare and UFO.
4. I also always liked that clean look of a pipe hidden in a belly pan. Like the old illusion.
5. I am planning on using one of my super tiger 90 engines and was concerned about the fuel tank area, so I elected to convert it to a tail draggers for simplicity and extra room in the nose. I also wanted to get 8178 fired up. LOL
6. I also wanted something quicker to build than the Mach 1 fuse. So I changed the way the fuse is built. I just don't feel like all of that carving of the top blocks. I built a Bridi Killer Chaos over the winter and loved the use of Triangular stock in the fuse top, I certainly made it easier to round off the corners. LOL.

Overall it should be a great flying bird. I haven't changed the wing and stab, or there locations.

And I think it will look pretty cool, when its done.

I hope you guy will agree.
