This SAB HPS Rotor Head System is found on newer Goblin 700 platforms such as the Thunder Sport, and Thunder T 700 sized helicopters.
HPS stands for "High Precision System". This head has been developed in order to Increase the usable rotor RPM range without having to change the the rigidity of the dampening system.
Furthermore, this solution allows an optimal control of the geometry even when large amounts of torque are introduced into the system.
With new HPS system, the head is very accurate and reliable.
This kit includes everything required to assemble a complete rotor head, with only needing a main shaft (sold separately) to complete the package.
