You can go here http://www.users.bigpond.com/sirexwasp/ And then look for Super Wasp. He changed a few things.

Heres How
Substitute the Spruce spars with two lengths of 1/4sq balsa.
1/8 balsa end plates instead of 3/16
Eliminate Vortex Plates, replace with 1/8 Vortex Vanes as shown in pics above, Covered seperatly and glued to top of wing with Silastic RTV
Use 9 ribs instead of 11, Two inner ribs are 4" from center as per plan, remainder evenly spaced along wing. (approx 5.75") You can see the ribs outlines thru the wing in the last image above

I thought I would try a few things I never tried before just to see lol.

1. Is I used blue insulation foam like you get in 4 by 8 sheets by about 3/4 thick at a home depot. I used that for the ribs and for the center of the fuse. The ribs are almost gone . Tried to make them lighter and went with a 6" between ribs for the 48" wing.

Note I did this since I thought I would save some money by using the foam but as most of you very good builders know I was wrong lol. If you do not mind building slow it is okay. But the cost of Foam Safe Super Glue far outweighted what I saved over balsa not to mention the time involved with cutting out the foam . The leading edge is not quit as blunt as the original plans but very close still 3" thick wing.

If you like I will do a little measuring and let you know what everything else is. I just used the Wasp plans as something to get ideas from. I also moved the horizontal stab towards the wing by 4" so the elavator will be infront of the rudder like a Cap .
