Modular Power System – Simple, Elegant, Beautiful: With the removal of a small handful of bolts, the entire power system will arise from the Goblin – cyclic servos, engine, rotor system, main gear system – allowing this helicopter to be adjusted and repaired with great ease.
Dual Belt Driven Performance – Simple, Robust, Light Weight: By utilizing a belt driven main motor, immense power can be transferred without the fear of gear failure. Belt driven systems are amazingly efficient, incredibly durable, and best of all, belt drive systems are ethereally light in weight, cutting out the complexity, noise and added weight of a torque tube drive system.
Aerodynamic Boom Shroud – Form & Function in One Beautiful Package: Italian designing takes one step further, coalescing the aerodynamic canopy with a near seamless transition to a carbon fiber tail boom covering. This aerodynamic shroud brings a unique beauty to the SAB Goblin, serving as an aerodynamic element that allows the Goblin to traverse the skies at mach speeds. Speed and power has never looked so good.
CNC Aluminum Flybarless Main Rotor System – Nothing but the Best: Taking full advantage of flybarless technology, the SAB Black Thunder is offered in a flybarless kit only, utilizing a bearing raced blade grip control system for the absolute in precision & control. Nothing was held back throughout this build, and you can expect nothing less when the Goblin takes flight.
Light Weight Build – Power that can be Used Like No Other: By building the SAB Goblin with a keen eye on weight, SAB engineers were able to shave critical weight by utilizing carbon fiber materials & a dual belt driven gear system, which brings the Goblin to new worlds of power & performance.
Patented Carbon Fiber Tail Boom – Strong, Light & Vibration Free: Reinforced with CNC aluminum for the utmost in strength, the patented carbon fiber tail system eliminates vibrations, allowing maximum rotor speeds to be achieved without the fear of vibration.
SAB Thunder Bolt Rotor Blades: Thunder Bolt blades are a drastic redesign of the older Black Line blades SAB offered. The TB Blades feature a variable profile and chord width from end to end, allowing for optimal lift at each critical point of the blade. This allows the TB Blades to be up to 20% more efficient than the Black Line blades. The tip of the blade has also been changed, to that of a tapered style which allows for increased efficiency, and lower noise due to lack of wasted energy in flight.
