RC Engine Needle Extension Rod & Switch Lever - K&S KS23791 Blue  [KS23791]

Durable extension rod with compact lever

This K&S KS23791 extension rod incorporates a switch lever in a compact assembly and is finished in blue anodised aluminium for wear resistance. It is intended to simplify needle adjustment and to provide a small, reliable manual switch actuator near the engine area.

Use is typically during maintenance, tuning sessions and bench checks for glow or nitro engines where a more durable, exposed control point is useful. The component functions as an aftermarket accessory to lengthen needle reach and to mount a simple lever switch nearby.

Installation commonly involves attaching to the existing needle linkage or substituting the linkage end and then aligning the rod for smooth operation. Basic tools suffice for fitting, and routine inspection will help detect wear or loosening before it affects control quality.

For operational reliability, the extension enables safe needle adjustments from a short distance and the lever gives straightforward mechanical on/off control for simple ignition or pump actuators. Verify fitment with your engine geometry and check fastenings regularly to maintain consistent action.
