The SIAF 2018, International Aviation Days held on Sept 1-2, at the Sliac Air Base, meant a good presentation in static and flight tours for Viper SD4 & Skyper GT9. Four Viper SD4 and Skyper GT9 aircraft in static tours have shown a real fleet that was viewed by SIAF 2018 visitors.
On both days, the Viper SD4 - "Air Force Trainer" - with excellent equipment for quality training, not just the Air Force pilots, was introduced in flight demonstrations. Skyper GT9 was the premiere in the flight display. Excellently, these flight demonstrations were presented by pilot Dušan Šamko, who documented great flight characteristics, perfect flight dynamics, whether in minimum or maximum speed.
