Hirobo HI0414218 Freya Eagle Tail Stabilizer Stopper D4mm  [HI0414218]

D4mm Stopper for Tail Stabilizer

This item is an RC-scale spare stopper for the Eagle Freya tail stabilizer assembly, listed as HI0414218 and compatible with D4mm stabilizer bars. It functions as a small mechanical stop that maintains the stabilizer bar position while adjustments are made.

The stopper is intended for maintenance and trimming duties, useful when setting tail gain and pitch behaviour. It should be treated as a precision replacement part rather than a structural component of the tail system.

Fitting requires sliding the stopper onto the D4mm bar at the required point, confirming clearance with the tail linkage, and performing a low-throttle motion check before returning the model to full flight testing.
