Hi Dan. Got your message, copied it below to make it a little easier for me to reply here. I’m replying here so I can include a reference photo which should answer a few questions..
In the kit I have on my shelf there are 2 separate wing panels and each is 13” spanwise for a total span of 26”. If you have a large enough piece of coroplast the kit CAN be built with a single piece wing with minor modification.
If you take your file to a blueprint shop (old school source) or anyone who has what is now called a large format printer (36” wide roll of paper by unlimited length) and have them print it out with a 26” wingspan all the rest of the parts should be the correct size.
As you can see from the photo the leading and trailing edges are BOTH swept, so I lined up the root and tip with the grid lines so the measurement marks would make sense.
I have seen lots of different names for the “signs” and yard signs is one. But yard signs are typically kind of small at least around here. A better source of free material is after an election to drive by every major intersection with a pair of diagonal cutters and cut down the bigger signs. Another source is screen printing shops and/or sign shops. Check their dumpsters or simply ask the production folks what they have. Both types of shops may have a few test pieces or scrap signs as it’s not cost efficient to wipe off all the ink if you have a few that are not up to par.
Let me know if I can help with anything else.

Hi Paul;
I was poking around the Knights of the Round Circle site tonight looking for information on the ET-1 trainer that Larry Renger designed and that you guys use for your C/L displays and such. I saw your name and thought I would ask you this as I have not heard back from Larry
I got some plan and instruction files from Larry Renger by email a year or so ago and now a friend and I are going to start cutting parts and such for a couple of these for our club. The plan drawing does not show any dimensions for wingspan and such. The plan prints out on a normal sheet of paper and I can scale it up from that. The instructions and such and threads that I have searched out on Stunthanger all mention building them from political yard signs. I got tons of those and I know the corrugations run the length of the shorter dimension, and the plan nor the photos I have seen don't indicate that there is any joining in the middle of any kind, so I am assuming that whatever the short dimension is on a standard yard sign is what the wingspan is?? I hope to get started cutting parts pretty soon but need dimensions. We are going to use them just like you guys do, electric power controlled by a radio. I may fool around with one powered by a Cox engine just for giggles and grins. Any information you can give me on size will be appreciated.
Thanks a lot and HAPPY HOLIDAYS!!
