Anyone have any info on a giant scale SIG Kavalier.

While in the hobby shop today they had a giant scale SIG Kavalier hanging from the roof that he got from the son of a guy who built. The guys AMA number was 109 so he probably had been at it a while..

Anyway this Kavalier had a wingspan of about 85" or so. Anyone know if this was a kit or a plans build? The guy said he had the plans but he was busy and I didn't look at them.

It was a pretty nice looking plane and had a big Super Tiger engine in, probably around a 3250 or something similar.

It looked like it would be a great sport flyer. Only problem was the one piece wing. I went in looking for a .40 size plane I could throw in the truck when I didn't want to hook up the trailer...but we know how that goes and you get distracted.
