Product overview
The Tianying Brothers X-14 is an agricultural flight platform combining mist spraying and material spreading around a 14 L tank. Its application arrangements cover liquid chemicals, granules and powdered fertilizer, with changes between systems supporting different field tasks. Listed uses include pesticide application, fertilizing, seeding, fish feeding, grass seeding and snow-melting material distribution. RTK centimeter-level positioning, fully autonomous operation, autonomous obstacle avoidance and terrain-following flight support its agricultural role, alongside a wide-angle FPV camera and high-definition digital image transmission.
The physical design combines folding arms, disc-type brushless motors and four downward-pressure spray nozzles. Folding the arms reduces the space needed for vehicle transport between work sites. The V-shaped tank serves both liquid and solid materials; its geometry is intended to reduce sloshing and improve stability, while allowing granules to descend diagonally under gravity. Dual filling inlets facilitate replenishment, with a stated diameter up to 113 mm. The charging management system provides one-button fast charging and automatic balancing.
Spraying flight must stop when wind speed exceeds 10 m/s. Operation also requires monitoring propulsion and checking for aircraft vibration or resonance, leaving a buffer area and avoiding flight toward obstacles where possible. A safe landing area is required when returning for chemical or battery replenishment, and the rotors must stop before battery replacement or chemical refilling. The operating instructions also call for a break of at least 15 minutes after each hour of continuous operation.
