A rich fleet of four Viper SD4 aircraft was presented at the largest airshow in the US EAA Air Venture Oshkosh (24-30 July 2017). A highlight of the presentation was the Viper SD4 with the Rotax 912 iS engine, a variable-pitch propeller and a towing hook, in the LSA category and another one a higher power of the Rotax 914 ULS 115 HP engine. In addition to these pieces, there was a Viper with a new LSA certificate issued by the US FAA.
Have a look at an interesting photo gallery as a well as video of successful American youtubers Jeff and Chris, who also visited our stand and recorded video as they are planning to buy an airplane. One of their choices was our Viper SD4.
