Payload weight limits and balancing issues with Archer 2 gimbal system when using heavy camera rigs and accessories

15 years old. Gear and prices may have changed since.

What the thread found

  • The Archer 2 stage is rated for approximately 15 kilograms maximum payload, and exceeding this causes premature wear on gimbal bearings and yoke damage.
  • When payload weight is concentrated high on the rig, the center post must be extended significantly and counterbalance weight added to the bottom, which accelerates gimbal degradation.
  • Accessory devices mounted high on the camera (such as antenna systems) create balance problems that force extended post configurations beyond normal operating parameters.
  • Adding extra battery packs to the rear of the monitor or below the centerpoint provides counterbalancing weight while distributing load more efficiently than dedicated weight kits.
  • Gimbal yoke damage can manifest as loss of smooth rotation between balanced and unbalanced states despite static and dynamic balance appearing correct.
  • Operating payloads near or exceeding manufacturer limits risks gimbal failure and poses safety hazards to operators and nearby personnel.

Depends on

  • Experience described is specific to Archer 2 with G50 arm and RED camera systems from circa 2011.
  • Exact weight specifications from manufacturer not provided in thread; ratings mentioned are approximate figures from experienced operators.
  • One operator reported successfully flying 40 pound payloads, suggesting some variation in actual failure points, though this was described as an exceptional temporary case.
  • Gimbal service outcomes not documented, making it unclear whether operating at maximum weight causes permanent damage or temporary adjustment issues.
  • No technical specifications provided regarding what constitutes the stage weight rating versus total system rating.
