Hirobo HI2522023 M2 x 130 Turnbuckle Adjust Rod for RC Helicopters  [HI2522023]

Linkage and trim adjust rod notes

This Hirobo adjust rod is an RC-scale linkage item defined as M2 x 130, intended where a threaded turnbuckle-style rod is needed in compact rotorcraft control setups. It is designed to be used as an adjustable connector between swashplate points, servo horns, or control arms that accept M2 threaded terminations.

The rod offers fine incremental adjustments for control geometry and trim. Modelers typically fit this in place of a fixed link to enable on-model trimming without altering surrounding components; remember to verify that your existing end fittings accept M2 threads, since the designation only reflects thread size and nominal length.

Use the rod as a basic threaded length adjuster: small changes will influence cyclic or pitch characteristics depending on location in the linkage chain. Adjust carefully and check control throws after each tweak to keep the machine safely rigged and predictable in the air.
