RE: Sterling kits (Rimfire, Lancer, & Lancer SL62)?
Ed,
The Rimfire does have a double tapered wing.... also.. the spin/snap charactoristics come from a very thing wing design... Honestly, I'd love to put an OS .61 mounted inverted in one and fly SPA with it... but.. I've got other birds that do that better.
I'll check the plans tonight see if you could scratch one from the plans..
