Hirobo HI0414218 Freya Eagle Stabilizer Bar Stopper D4mm Helicopter Part  [HI0414218]

Tail stabilizer stopper, D4mm

This is an RC-scale replacement stopper designed for the Eagle Freya helicopter tail stabilizer system. The part is listed as HI0414218 and matches the D4mm stabilizer bar sizing shown in the product name, serving as a small mechanical stop that keeps the tail stabilizer bar positioned during setup and flight tuning.

In practical use the stopper functions as a service or spare item for maintaining tail geometry and for making incremental adjustments while setting tail gain and pitch behavior. It is intended for model-level work on the Eagle Freya series and should be handled as a precision small part rather than a structural component.

Installation is straightforward on compatible D4mm stabilizer bars: confirm alignment with the tail assembly, fit the stopper onto the bar at the required location, and verify range of motion before test flights. Use standard RC maintenance practices when replacing or adjusting this part to maintain reliable tail rotor response.
