Boom Racing 3S Muscle Winch High Voltage Direct Power


Boom Racing's Muscle Winch™ is a dedicated and fully waterproofed internal servo winch designed and engineered from the ground up, delivering strong pulling power and reliable performance for any R/C builds.

Free Spool Unit:

A dual-trigger free-spool unit is integrated into the Muscle Winch™ for a quick winch release. There are two ways to trigger the free spool mechanism; one by pressing the button on top of the servo winch, and the other by pulling the knob on the bottom. This dual-trigger design makes the free-spool unit accessible from both sides of the servo winch, which is a major advantage when designing the layout of your servo winch placement.

To release the rope, press the button on top of the Muscle Winch™ or pull the knob from the bottom. This will disengage the locking mechanism allowing you to pull the rope out. Once you have reached the desired length, then release either the button or knob and continue pulling on the rope until you hear a “click” sound. The locking mechanism will re-engage and you are ready to winch.

The Muscle Winch can also be used without the free spool. You can use the radio to release the cable.

The Muscle Winch™ operates at up to 12.6V which produces up to 40KG (555oz) of torque and features a billet aluminum case and full metal gears for strength and durability. A metal scale winch hook is included for the icing on the cake!

Requires a spare channel with a three-position switch to control the winch.
