Freefly 12 mm Rail Payload Mount Kit adds a robust twin-rail interface to Alta X with 500 mm (19.7 in) carbon tubes at 149 to 150 mm (~5.9 in) spacing. Precision-machined aluminum brackets and quick-adjust levers keep weight to 6.6 oz and speed COG tuning for third-party payloads.
Freefly 12 mm Rail Payload Mount Kit gives Alta X a robust, lightweight twin-rail interface for third-party cameras, sensors, and accessories. The kit uses 12 mm (≈0.47 in) carbon tubes at 500 mm (≈19.7 in) length with a 149–150 mm center-to-center spacing (≈5.9 in) that matches common rail-mount payloads. Precision-machined aluminum brackets keep the structure rigid while holding system weight to just 6.6 oz.
Setup is fast and repeatable. Bright red quick-adjust levers make center-of-gravity tweaks obvious, lock securely for flight, and break down quickly for storage. The kit integrates cleanly with Alta X that has landing gear attached to the chassis and pairs naturally with Freefly Skid Landing Gear for under-belly payloads that need extra clearance.
Secure, Flexible Payload Interface
- Twin-rail standard: accepts payload brackets designed for 12 mm rails with ~149–150 mm spacing.
- Third-party ready: supports gimbals, instruments, and custom fixtures without custom machining.
- Rigid attachment: carbon fiber rails and aluminum mounts resist torsion for stable imagery and repeatable alignment.
Light, Strong, Field-Friendly
- Low mass: 6.6 oz in use to preserve flight time and payload headroom.
- Quick adjustments: visual lever position checks, fast COG tuning, and simple breakdown after the mission.
- Complete kit: includes fasteners and driver for the first install on the Alta X chassis.
Built for the Alta X Ecosystem
- Alta X integration: designed for airframes with landing gear mounted to the chassis.
- Pairs with Skid Landing Gear: add clearance for larger optics or downward-facing sensors.
*Landing gear, Alta X airframe, payloads, and gimbal mounts shown in photos are not included.
