I got the foam cores laid out to match the VooDoo plan in the Goldberg Double VooDoo kit.  The cores will be cut 24in. long.  Standard VooDoo is 18in.  Any cut off is just waste at our end.  You just might like how a 52in., 485 sq. in. with a 5.8 aspect ratio flys.  Basically the foam replaces the leading edge, alignment spar, and the trailing edge and center section sheeting.

Since this is simple, easy to cut, and wastes less foam the price is $15 per set. A max of 3 sets will fit in a USPS PRICE size box.  Shipping is usually ~$16 - depends on the clerk.  Plus the USPS tacked on a $4 charge for anything over 4" thick.  BOOO  HIIISSS.

PS  Look Up Tom Luciano.  He had one flying just like a stock VooDoo at the Vintage Flying at the Circle Burners field a few weeks ago.
