Ribless delta...LOOK!
I have basicly stolen Rick Haslams idea of the Wild Wizz 40, only about 1" longer, about 1" narrower and about 1/2" thinner airfoil, MAYBE a little more streamline (I said MAYBE).
It's just a 1/4"x1/2" frame with tapered spars and 1/8" liteply cap strips bent over them. The engine mount is 1/4" aircraft plywood and the radio box, center sheeting and hatch is 1/8" balsa, very easy and cheep to build, a lot of this wood came from my scrap box in fact.
This is my 4th "Wizz" including the origional kit I built so I know it will go like a bat out of hell and tough as nails to boot. I have built all of them with a single fin with rudder and they will do some crazy flat spins and snap rolls as well.
I'm off all next week so finishing it up should be a snap! This is the result of less than 1 days work.

RE: Ribless delta...LOOK!
When I first saw this construction technique I wasn't sure about it, but now I think it's the only way to go. The cap strips are like bicycle spokes, just one by itself is very flimsey, but put a whole mess of them under a load and you got something. The origional Wizz design has 2-1/16" caps laminated together, this is very light but not quite as strong as the light ply, I kept knocking holes in them.
As far as amesia, it's to easy to build to forget how
, all you need is an outline drawn out on a paper and off you go. You could build it one day and fly it the next after you get the hang of it.

RE: Ribless delta...LOOK!
It is basicly ready to cover, actually it is about 95% covered now and should be completed today.
The span is 34", length (frame only) is about 23", and the tips are 6". I'll post another picture when it's complete.
