TRX4 Pendulum Knuckle Wheel Weight, Alloy Lid, 9mm Hex TRX4023C by GPM  [TRX4023C]

Weighting pendulum for precise crawling control

This 16 pcs pendulum wheel knuckle axle weight set is an RC-scale accessory intended to increase wheel downward force on TRX4 crawler chassis. The assembly places mass low with a brass body, alloy lid and stainless steel rolling beads to improve tyre contact when negotiating small indentations and soft ground.

The package contains a 9mm hex adapter that is wider than stock, allowing use with wheels that accept the larger hex, together with screws, shims and washers for mounting to the outer knuckle case at the front and rear. You can change the number of stainless beads to adjust how much pendulum mass each wheel carries.

Materials were selected for consistent mass and corrosion resistance: brass for the main weight, alloy lid, and stainless steel beads and fasteners suitable for muddy or wet running. This item is a tuning part for RC crawling and should be fitted and tested only on model vehicles.

Adjust bead quantity and placement to match tyre choice and terrain for steadier low-speed crawling on TRX4 models.
