I live about 1 hour from Joe Nall, and went there with the idea I was coming home with something, well I did, but I do not know what it is, I told the guy selling it, I cannot fly that kind of plane very well, he said if I take $50 off the price, would that make you fly it any better,Ha, no but I hauled it home anyway.
Here is what I know for sure.
It was built from a kit, the builder handwriting is inside the fuse.
Wingspan 96.5 inches
length 86 inches
weight 18 lbs without engine or any electronics
bolts are not metric
wing tube is 1.25 od aluminum 16inch with wooden dowl in the middle, overall length is 32.875
Here are the pictures.
