The SAB Goblin 500

By utilizing a dual stage belt drive  system, the Goblin 500  transfers this power to a helical output gear,  which in turn drives the  main rotor system and driven tail rotor system.  Simply put, the power  this system can handle is fearsomely evil.

Ingenuity  flows throughout the Goblin, taking shape in the patent  pending  horizontal servo mounting system that directs servo torque  directly to  the flybarless main rotor system via short, stiff linkage  rods that  rotate via bearing raced support. This system is intensely  strong,  allowing power transfer to be as direct as mechanically  possible,  resulting in precision & rigidity that is simply  unmatched.
