Martenson,

Can you show us with pictures the way the fuse of the Mach 1 is twisted?
When it is the tailcone, maybe a solution is to open the devision seam on the bottomside of the tailcone and remount this is the straight position of the fuse.

Before make any pictures, clean up your workbenche, because you cannot make pictures outside now I read! (LOL).
