Eagle Freya Linkage Pitch Arm - Hirobo HI0406003  [HI0406003]

The Hirobo HI0406003 pitch arm set is offered as an RC replacement part for items listed under Eagle Freya helicopter spares. It transfers servo motion to the rotor head and is a purely mechanical component within the collective pitch system.

Installation notes: confirm servo neutral and control throw prior to fitting, centre blade pitch with the rotor head at trim neutral, and check for smooth, end-to-end travel without binding once installed. If you encounter any fitment issues, compare with the model parts diagram or contact the supplier for clarification.

Tuning role: the pitch arm impacts pitch sensitivity and hover balance. Slight differences in arm length, horn setting, or linkage geometry can change pitch rate and trim, so validate adjustments during ground checks and subsequent flights.
