The Eagle Aircrafts Viper SD-4 is set to disrupt, if you ask Wayman Luy. It’s aggressively priced, he said, and available in either SLSA, ELSA or as an Experimental kit build airplane. And you can have one in three to four months if you order now. Plus, with a peppy Rotax 914 iS in the demo model brought to Sun ’n’ Fun by Wayman Aviation, this pilot discovered that the Viper SD-4 is just plain fun to fly. Ergonomics are a delight for such a small airplane. Though the semi-reclined, well-cushioned seats are fixed, the rudder pedals have an innovative flip button that allows a two-inch extension, making it possible for this five-foot pilot to reach the stops. Three EFIS screens (two Dynons and a panel-docked Garmin 695) light up just before the liquid-cooled Rotax purrs to life.
