What the thread found

• The Zephyr arm uses similar structure to the Flyer arm but with heavier springs, making it a potential source for upgraded springs, though compatibility is uncertain
• Manufacturers typically do not sell upgraded spring kits separately and will not endorse modifications that exceed the specified weight limits
• Some operators have successfully flown camera packages significantly over the stated weight limit by careful balancing and positioning of equipment, though this risks damage to the gimbal and top stage
• Surgical tubing modifications do not produce satisfactory arm behavior compared to proper spring upgrades
• Replacing the entire arm with a Zephyr model is the officially supported path for operators consistently working beyond weight specifications

Depends on

• Whether Zephyr springs are physically compatible with Flyer LE arms is unknown and untested
• Exceeding weight limits may overtax the gimbal and top stage even if the arm itself can support it
• Manufacturer support explicitly does not cover modifications beyond specification
• Only one person reported actual experience flying significantly over limits, suggesting this is not typical practice
• Exact weight capacities and spring specifications vary by generation of the equipment
