Installation angle & tips

• Position the fiber optic disk outlet away from propellers and consider aircraft center‑of‑gravity balance.
• Set the mounting bracket to match the aircraft tilt; keep the outlet close to horizontal. Reference angle shown (35° diagram).
• During winding with special glue, for the first ~200m coating area, limit flight speed to ≤30km/h or ≤8m/s.
• Maximum flight speed should be ≤120km/h.
• Version 4.0 waterproof version can touch water; other versions should avoid water to prevent optical transmission degradation.

Connection methods (reference diagrams)

• Ground‑side wireless connection I: GBD to receiver/VTX; SKY to flight control.
• Ground‑side wired connection II: GBD to remote control link board.
• Dual control link I: SBUS protocol mode.
• Dual control link II: CRSF protocol mode.
