TRAXXAS TRX4 TQi Steering Wheel Extension TRX4ZSP43 technical fitment by GPM  [TRX4ZSP43]

TQi wheel extension engineered for TRX4 fit

This steering extension repositions the wheel on TRAXXAS TRX4 TQi transmitters to enable one-handed operation while maintaining the radio's original electronics and wheel spline integrity. The component is produced by additive manufacturing to keep mass low and preserve steering responsiveness.

Technical notes:

• Intended function: relocate the transmitter wheel to permit comfortable single-hand inputs for TRX4 scale crawling without internal modification.
• Production method: 3D printed using a lightweight material selected to limit added inertia and maintain usable grip characteristics.
• Assembly: remove the factory steering wheel, engage the extension buckle onto the transmitter hub, and verify mechanical engagement before field use.

Installation guidance: the fit is a mechanical interface for TQi-style steering wheels on TRX4 transmitters; confirm hub geometry before installation and tighten only as required to avoid spline stress.

This extension offers a straightforward, removable solution to adapt TRX4 TQi transmitters for one-handed steering while allowing quick reversion to the original wheel layout.
