I am interested in exploring your range of agricultural drones, specifically the ones designed for pesticide spraying. I'm looking for a model that offers a 30-liter capacity for fume application, as this would greatly enhance efficiency and productivity on our farms. It's essential that the drone is user-friendly and integrates advanced technology for precision in spraying, while also being durable enough to handle various agricultural environments. Additionally, could you provide information on the specifications of your agricultural fumigation drones, including any unique features they may have? I'm particularly keen on understanding their operational range, battery life, and maintenance requirements. Please let me know about your pricing, minimum order quantities, and lead times for delivery. I look forward to your detailed response and any available brochures or product sheets.
