Product overview
The Hongfei HBR T25 is an electric agricultural flight platform for applying liquid crop treatments and spreading solid fertilizer across farmland and orchards. Its carbon fiber body, aluminum alloy landing gear and 7075 aviation aluminum structure combine a 16KG stated weight with a 51KG maximum takeoff weight. Overall dimensions are 2010mm*1980mm*750 mm, reducing to a stated transport size of 1300mm*1300mm*750mm. The transport package is an airline box. A quick-plugging bucket provides the refill interface, with a stated 50% reduction in refilling time.
The liquid application configuration has a 25L payload, a 6-10L/min spray rate and a 4-8m spraying width. Solid application uses a modular spreading system that accepts 0.5 to 5 mm particles; its maximum width is 15 meters and throughput can reach 50kg per minute. GPS positioning, terrain-following radar and front and rear obstacle avoidance radar support automated operation. The described power configuration pairs a 14S 42 000mAh lithium-polymer battery with a four-channel smart charger. Plot planning supports 128 waypoints, alongside edge-sweeping and fruit tree modes.
