RE: Is anyone interested in a GP Supersportster build?
Hmmm! Dont understand this. Mine was a rocket alright (SS60 with an ST75). But also lands as slow as a trainer. Most of the others I've seen would land pretty slow too. Thats one of the things I tell my students that move on up, the Super Sportster series have a pretty wide flight envelope. That thick wing makes a pretty good floater and the kits make a good and rugged airframe. Just my opinion.
