What operators found

• The Smart System X1 arm is lighter and more compact than the Pro Titan, making it comfortable to operate.2026 General Discussion
• Typical upgrades in sequence are the vest and arm (ArmX1 Lite or Lite+ specifically developed for the Axis sled, NB Band Arm, or skeleton vest), a Low-Mode Monitor mounted to the front rods, a stiffer or additional battery plate, digital horizon display, and monitor yoke; operators report that the standard A30 arm presents challenges with footwork and horizon holding.2025 Facebook
• The SmartSystem ArmX1 Lite is designed for the Axis, using the same 1/2-inch pin as the Axis handle, with springs adjustable via the sled and federated spring sets for different loads and a slim profile; the Plus version increases arm capacity alone and would exceed Axis limits.2025 Facebook
• The SmartSystem ArmX1 offers multiple spring set combinations; the manufacturer provides a configuration table (version 1.0 and later versions available on the maker's website).2025 Facebook
• Before working with XTune, set it to minimum and first select the correct spring combination for the load—use as few springs as possible, but compressed strongly.2024 Facebook
• The SmartSystem Arm X1 is noted as slim (obstructing less of the monitor), offers superior iso-elastic performance compared to both Tiffen arms, exhibits high build quality, is cost-effective, and has higher payload capacity; tool-free adjustment of carrying capacity and iso-elasticity via a knob is cited as the primary advantage of Tiffen G50X and G70X models.2023 FacebookDisputed
