With a wing span of just 2" more then a clipped wing Dust the building area does not need to be very big. We will see if i can build it on a 30" x 40" dinette table.

For phase 1 of the building I gathered up the spars, ribs, engine mount, firewall, 1/4" dowel and two screws. The airfoil is a NACA 0006 but with the #1 ribs being over 22" long the maximum thickness is a little over an inch. The engine mount is just over 3" long so the engine can be set back far enough for a spinner to be close to the nose ring. I guess a rear intake fan engine would fit with a little effort.

I kept trying to think of a good way to attach the spars to the last rib and came up with a way I think will work well. I put a 1/4" dowel in the end of each spar with the long spar dowel cut off flush and the front spar dowel sticking out 3/16". The #4 rib height would not allow drilling a 1/4" hole and still be strong.

To make sure the airframe was straight I used two 1/2" hardwood rails with 3/16" supports as seen in the picture below. I just push down on the spars and everything aligned perfect. Thin CA glue on every joint except the last rib with a screw in it.
