The Viper Ring - is an unpredictable flyer that will most definitely leave you in wonder. Our test pilots at PaperHangar are still baffled in the operations and aerodynamics of this slick airfoil. Our engineers at PH have designed, redesigned, and reconfigured every aspect of this crazy bird and found similar results in flight characteristics. Our engineers have come to the conclusion that it doesn’t matter where its folded, rather how its thrown.
