RC Helicopter M2 x 130 Adjustable Turnbuckle Rod - HI2522023 by Hirobo  [HI2522023]

Turnbuckle adjust rod for precise 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 serves 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 often replace a fixed link with this part to allow on-frame tuning without modifying surrounding hardware; the name shows thread size and nominal length only, so confirm existing linkage end fittings accept M2 threaded rods before ordering.

When planning setup, treat the rod as a simple mechanical link: a single threaded element that alters overall link length and can affect cyclic or pitch response depending on its position. Make small adjustments and verify control throws after each change to keep the model safely rigged.
