The latest technologies and CAD systems, as well as CNC machining, are used in their manufacturing.

The uniqueness of Viper SD4 is also in the fact that it is one of the few planes in its category that have successfully passed the elasticity tests of all its parts, the so-called Flutter tests. Viper SD4 successfully mastered the SPIN tests, which are necessary for obtaining a certificate EASA CS-LSA. Viper SD4 RTC has been certified according to EASA certification specifications CS-LSA Amdt.1. EASA.A.606
