SAB Goblin Kraken 580 Electric RC Helicopter Kit SG580

With the Kraken, SAB Heli Division embarked on a journey of innovation, incorporating original solutions inspired by feedback from their customers and pilots. This aircraft's reinvention brought a plethora of enhancements, setting it apart from the rest of the Goblin line.

The most noticeable transformation is the fully enclosed powertrain, a unique feature compared to other Goblins. As soon as you open the Kraken box, you'll witness this change, emphasizing user-friendly design. Moreover, there are numerous upgrades setting the Kraken apart, such as independent belt shafts for the transmission and tail, simplifying assembly and maintenance. The new, ultra-light 7075 aluminum alloy rotor head and tail case contribute to the Kraken's remarkable performance and crash durability, all while maintaining a lightweight airframe of just 2680g.

The Kraken's design diverges from the standard 700-sized model with an entirely unique approach. SAB's commitment to original solutions and innovation remains apparent throughout the aircraft, inside and out. Its full body and integrated frame design, coupled with a detachable boom system, improve crash resilience and flight performance.

The Kraken boasts a wide range of dampening setups, ensuring adaptability to various pilot preferences. The damper system, comprising three O-rings for rigidity and a techno-polymer damper for spindle movement, enables customization of the model's response.

SAB's meticulous engineering is evident in every detail, including 7075 T6 aluminum blade grips and 6061 T6 aluminum blade grip arms. These components enhance durability and simplify maintenance, ensuring a quick and efficient repair process after a crash.

The powertrain supports three shafts: one for the rotor head, one for the motor, and one for the tail. The one-way system inside the module is robust, reliable, and low-maintenance, capable of transmitting power without issues, even in case of a crash. The Kraken simplifies cable management with a clever wire support solution.

The airframe utilizes high-end materials, such as carbon fiber for the main frame and a composite tray with rubber edges to protect wires. The redesigned ultra-light tail case allows quick tail fin replacement, contributing to the model's strength and reliability.

The plastic battery tray, wider than previous versions, provides a secure and convenient way to mount batteries. It includes a carbon fiber battery protection, double-sided tape, and battery straps.

The landing gear, similar to that of the Kyle Stacy Goblin 700, offers robust support for hard landings and skid bumps. Thread lock is recommended for screws threaded into metal to prevent stripped bolt heads or broken screws.

Some parts come factory pre-assembled, and meticulous checks ensure correct assembly and thread lock application. Notably, SAB's manuals are renowned for their clarity and detail, providing comprehensive information for building and configuring the Kraken. From motor mount specifications to ratio configurations, the manual is a valuable resource.

The Kraken represents SAB's commitment to innovation and user-focused design, making it a remarkable addition to the world of RC helicopters.
