Swyper CHB - Home Built Delta Wing Swappable

Ok, so I've been working on this for about three weeks now, and I think I've got it figured out.  I've made a couple different versions of it, and am just now getting this one dialed in.  I'm calling it the Swyper CHB, don't ask why.  I just made it up.

I've thrown together some measurements on a very, very primitive drawing (Gimp 2).  I'm trying to find a program that is easier to put together plans with, so if you have any suggestions, I'd love to know what everyone is using.

I designed the plane to use one sheet of 20x30 Dollar Tree foam board (minus the swappable fuse).  I think it turned out all right.  Will fly nice and slow, but clips right along with full power.  With the right motor, it would scream.  The first one i built had smaller elevons, so I made them much bigger on the second version.  I used a KM step for the leading edge of the wing.  It also make the wing much more stiff (no spars needed).  I didn't mount landing gear, as i don't intend on using it.  This will be followed by a similar version with added rudder/s.

The plans show half of the wing, so the total shown dimensions are 20x15, simply copy the dimensions to the other side of the foam board.

The CG seems to work well at around 7-7 1/2 inches from the firewall.  I've messed a little with the CG, but i keep coming back to this.

For the plans for the Fuse, i used the original Nutball plans.

Josh's Delta also has good plans for the fuse, including landing gear.
