What the thread found

• The Zephyr arm weighs 9 pounds and the sled with SD monitor weighs 6 pounds 5 ounces without Merlin weights
• The sled length is adjustable from a minimum of 22.5 inches to a maximum of 36.5 inches
• The Zephyr arm has nearly identical outer dimensions to the first-generation Flyer arm, with the main differences being a 0.5-inch wider elbow and slightly heavier springs
• A Panasonic HPX500 with Canon kit zoom required one Hytron 50 counterweight and was balanced with the sled extended to 22 inches
• The arm post on the Zephyr is removable and can be replaced with a 10-inch extended post
• The vest features ratchet straps, a sturdier vertical spar, more rigid hip material, thicker pads compared to the Flyer vest, and adjustable shoulder clips using velcro straps
• Published specifications indicate a 30-pound arm lift capacity with a 24-pound payload limit, but the combined weight of sled and payload does not reconcile with these numbers
• The Zephyr monitor does not appear to have image flip capability and lacks documentation and remote control

Depends on

• Testing was limited due to a malfunctioning camera quick-release plate, preventing full arm tests
• No complete weight balancing or dynamic balance optimization was performed during initial testing
• Monitor specifications were not provided by the manufacturer at the time of testing
• Discrepancy between published arm lift capacity and payload limits remains unexplained and unresolved
• Individual arm units may have varying spring tensions and lift capabilities
• Testing was conducted with limited time available for comprehensive evaluation
