The kit is designed for pattern flying and 3D aerobatics as well. Slim wings with a unique thin sharp airfoil allow the ultimate to use gas engines from up to 120cc sizes and give it an approximate final dry weight around 33lbs or 15kg.
Features of the 39% Ultimate 300KS ARF
The Ultimate 300KS Kit Includes:
Krill decided to improve the Ultimate's flying characteristics and in cooperation with the great Italian pilot Sacha Cecconi they created an updated MK2 version built on the strong base of the current kit and tested with Krill's pilot Marek Plichta.
Krill also decreased the overall weight at the same time with reinforced wings (updated wing spar) for higher drain during aggressive 3D flying. They Fixed the cabane inside the fuselage, added interplane struts, replaced the tank holder and installed the rudder servo tray. Main landing gear attachment was also redesigned. Gabriel horns are used on all control surfaces, as well as, new builder friendly servo fixing on the wings.
Important Note: Using more powerful engines such as a 150cc or larger will void the factory warranty of the airframe.
