K&S KS1470 Helicopter Rotor Blade Balancer EP-2  [KS1470]

Rotor blade balancer for RC helicopters

This K&S KS1470 rotor blade balancer is an RC-scale accessory designed to help hobby pilots and model technicians achieve even mass distribution across helicopter rotor blades. It serves as a diagnostic and setup tool to reduce vibration and improve flight trimming by showing which blade or tip weight needs adjustment.

Use is straightforward: mount a blade on the balancer's arbor, observe the low side, and make small weight adjustments until the blade rests level. The device is intended for routine pre-flight checks and tuning sessions where balancing contributes to smoother rotor tracking and reduced wear on bearings and servos.

The balancer supports both main and tail rotor blades common to hobby helicopters, and it fits into workshop setups for bench tuning and maintenance rather than in-flight modification. It is presented as a lightweight, portable aid for model-level setup tasks.
