Technical overview for Revo linkage upgrade

This precision throttle mixing arm is produced as an aftermarket upgrade for Traxxas Revo linkage, designated RE-051/S. The design focuses on lowering pivot friction by using two ball bearings, improving repeatability in throttle actuation.

Functionally, the part replaces the original mixing arm to provide a tighter rotational interface between the servo link and the throttle mechanism. Bearings at the rotation points reduce hysteresis and the step-like feel that can develop as plastic arms wear, aiding finer throttle control during tuning and throttle trimming.

Fitment guidance: install onto the existing linkage pivot points, ensure each bearing seats squarely in its bore, and validate free motion through full servo travel. During bench setup, verify neutral throttle alignment and check for any end-of-travel interference; adjust linkage length or clevis orientation where necessary to achieve repeatable idle and full-throttle positions.

What precision checks should I perform on fit?

Confirm bearing runout is minimal and the arm pivots without lateral play; fit bearings flush to avoid preload.

Are the bearings serviceable or sealed?

The supplied ball bearings are sealed for low maintenance; light, plastic-safe lubrication can extend life in dusty conditions.

Will this assist fine throttle tuning for performance driving?

By reducing pivot friction and irregular movement, the arm supports more consistent throttle inputs which helps when making fine tuning adjustments.
