SAB Kraken Orange/Black

Enclosed Gear Box System
While still under wraps, the designers and testing during development has delivered incredible durability through flight and crash testing. An enclosed design provides simplicity for the end user, as well as never before seen longevity thanks to it’s generously oversized bearings, and other secret patent pending designs.

Kraken Rotor Head – Performance and Durability
The Kraken Rotor Head provides users with several updates. First and foremost is the Rotor Head, & Blade Grips are manufactured from 7075 aluminum. When paired with the Blade Grip Arm (the disposable part in a crash), that is manufactured from 6061 aluminum, and serviceable from outside the rotor grip, both building the new kit, and maintenance will be a breeze. Additionally, there are two Blade Grip Arms offered for different flying styles – spacing 26mm from the center of the rotor head, and 30mm. 26mm provides a higher response rate, and 30mm will provide a higher resolution feel.

Kraken Tail Rotor

While featuring a standard tail group design with a pitch slider and lever, SAB ensured performance of the Kraken was at the top of the design list in every way possible. Shedding 22% of the weight over previous Goblin tail groups, the Kraken not only incorporates a powerful and reliable tail system, but adds small amounts of performance gain by removing weight far away from the CG – aiding in Flybarless performance, and flight characteristics.
