Crafted with T300 carbon fiber, a 680mm extra-long wheelbase, and an all-round reinforced structure, this frame is tailor-made for 15-inch large models. It easily carries heavy accessories (multiple large batteries, pro equipment) and stays stable in complex outdoor conditions, serving as a solid base for ultra-large FPV working devices.

1. Aerospace-Grade T300 Carbon Fiber: 5x stronger than same-size metal frames, only 730g. Fixes metal frames’ "heavy, limited endurance" issue; supports 15-inch propellers and heavy loads (logistics, large-scale spraying).
2. 680mm Extra-Long Wheelbase: For 15-inch propellers, 60% better wind resistance than small/medium wheelbases. Reduces shaking in turbulence (clear shots, precise operations); 20% higher propulsion efficiency than 13-inch models for long heavy-duty flights.
3. All-Round 10mm+ Reinforced Structure: 10mm arms, 4.0mm top/base plates, integrated key connections. Withstands torque and collisions, resists deformation, extends service life, and cuts maintenance costs.
4. 40mm Spacious Internal Space: 14% larger than 35mm conventional space. Fits 6s-8s batteries/80A-100A ESCs, supports parallel battery installation. Reduces overheating; easy to add GPS, sensors for upgrades.
5. 30*30mm Standard Motor Holes: Fits 4214/4218/4312 high-power motors. 30% higher load-bearing than small holes; no extra drilling, easier assembly.
6. Full Compatibility & Flexible Procurement: 19mm camera + 30.5*30.5mm flight controller mounts work with most parts (no adapters); 10000PCS bulk saves cost, customization available.
