TRAXXAS TRX4 Compact Steering Extension TRX4ZSP43 by GPM  [TRX4ZSP43]

Compact steering extension for TRX4 TQi radios

This compact extension relocates the steering wheel on TRAXXAS TRX4 TQi transmitters so single-hand operation is more ergonomic, while leaving the transmitter internals unchanged. It is intended as a simple, removable upgrade for trail use.

Practical notes:

• Purpose: change wheel position to allow one-handed driving with a TRX4 scale crawler.
• Material and weight: 3D printed from a lightweight filament to reduce added mass and improve grip contact.
• Mounting: take off the stock wheel, clip the extension buckle to the wheel hub, and ensure it is firmly engaged before use.

Installation notes: designed for TQi-style wheel hubs used on TRX4 transmitters; confirm hub compatibility and avoid excessive torque when tightening to protect the wheel spline.

The extension makes one-handed steering straightforward on TRX4 radios while remaining removable for conventional two-hand control or transport.
