Hirobo HI2522023 ADJUST ROD M2 X 130 turnbuckle linkage rod for RC helicopters  [HI2522023]

Adjust rod for linkage and trim

This HIROBO adjust rod is an RC-scale linkage component specified as M2 x 130, intended for use where a threaded turnbuckle-style rod is required in small rotorcraft linkages and similar control systems. The part is built to serve as an adjustable link between swashplate, servo horns, or control arms that accept M2 threaded ends.

Functionally the rod provides fine length adjustment to set control geometry and trim; installers typically replace a fixed link with this part to allow on-airframe tuning without modifying surrounding hardware. The naming indicates thread size and nominal length only, so confirm existing linkage end fittings accept M2 threaded rods before ordering.

When planning setup, consider the rod as a straightforward mechanical link: one end-to-end threaded element that adjusts overall link length, affecting cyclic or pitch response depending on its location in the control chain. Keep adjustments small and check control throws after each change to maintain safe rigging for the model.
