RE: LETS SAVE SIG BEFORE THEY GET SWALLOWED BY THE BIG TWO!!!
Champion Stampe, Royal Midi Corsair, Ace Cloud Dancer, Tower Uproar, Great Planes PT40 and Gee Bee Tiger Moth but no Sig. I never really found a design I liked for the price. I guess if I hadn't run into a great deal on the Goldberg Tiger 60 (built and basic covering) I might have gone with the 4*60.
