Yuhui UAVs are Chinese UAVs developed by Chengdu Elm to Draw (Yu-Hui, or Yuhui) Information Technology Co., Ltd. (YHIT, 成都榆绘信息技术有限公司), mainly for aerial survey and surveillance applications. Some of the UAVs are jointly developed with other Chinese UAV developers, but all UAVs utilize the same ground station (GCS) that is capable of controlling different types of UAVs. The GCS is very light with weight less than a kilogram, and has a compact size of 65 cm x 35 cm x 16.5 cm. The adaptation of a general purpose UAV has greatly reduced the cost of operation.

  • Deployment time (from storage to airborne): 5–10 min
  • Recovery time (from landing to storage): < 5 min

    • Orange Colored Hawk

    Orange Colored Hawk (Cheng-Se Zhi Ying, 橙色之鹰) is a UAV of conventional layout and with tricycle landing gear. Propulsion is provided by a two-blade propeller driven by a tractor engine mounted in the nose. Specification:

  • Wingspan: 2.7 m
  • Length: 1.97 m
  • Max take-off weight: 18 kg
  • Payload: 3 kg
  • Max speed: 80 km/h
  • Cruise speed: 50–70 km/h
  • Ceiling: 4 km
  • Endurance: 2 h
  • Range: 100 km
  • Max wind scale allowed for operation: 5
  • Operating temperature: -20 to 55 °C
  • Storage temperature: -30 to 65 °C
  • Deployment time (from storage to airborne): 3 min
  • Recovery time (from landing to storage):< 5 min

    • Blue Hawk

    Blue Hawk (Lan-Ying, 蓝鹰) is a gasoline-powered UAV of conventional layout with tricycle landing gear. Propulsion is provided by a two-blade propeller driven by a tractor engine mounted in the nose. Blue Hawk is a larger cousin of Orange Colored Hawk with increased payload, speed, endurance and tolerance of greater temperature range, and is launched by conventionally taxiing. Specification:

  • Wingspan: 3.6 m
  • Length: 1.8 m
  • Height: 0.47 m
  • Max take-off weight: 50 kg
  • Payload: 10 kg
  • Max speed: 80 km/h
  • Cruise speed: 50–70 km/h
  • Ceiling: 3 km
  • Endurance: > 4 h
  • Range: 30–80 km, depending on the range of the communication gear carried
  • Max wind scale allowed for operation: 5
  • Operating temperature: -40 to 55 °C
  • Storage temperature: -40 to 65 °C
  • Deployment time (from storage to airborne): 5 -10 min
  • Recovery time (from landing to storage): < 5 min

    • Little Egret

    Little Egret (Bai-Lu, 白鹭) is a gasoline-powered UAV of conventional layout with tricycle landing gear. Propulsion is provided by a two-blade propeller driven by a tractor engine mounted in the nose. In comparison to Blue Hawk UAV, Little Egret has greater payload without increasing weight, and has stronger wind resisting capability, while flying faster. Specification:

  • Wingspan: 3.2 m
  • Length: 1.8 m
  • Height: 0.47 m
  • Max take-off weight: 50 kg
  • Payload: 20–30 kg
  • Max speed: 70–120 km/h
  • Cruise speed: 50–90 km/h
  • Ceiling: 3 km
  • Endurance: > 4 h
  • Range: 30–100 km, depending on the range of the communication gear carried
  • Max wind scale allowed for operation: 5–7
  • Operating temperature: -40 to 55 °C
  • Storage temperature: -40 to 65 °C
  • Deployment time (from storage to airborne): 5–10 min
  • Recovery time (from landing to storage): < 5 min

    • Swift III

    Swift III is an electrically powered micro air vehicle (MAV) of the Swift series, which is also manufactured by other Chinese UAV developers in addition to Yuhui, such as Zero UAV Intelligence Technology Co., Ltd. (Zero UAV, 零度智控智能科技有限公司) Externally, Swift III resembles a miniature version of Northrop X-4 Bantam without the inlets because Swift III is powered by a two-blade propeller driven by a pusher engine mounted at the end of empennage. Specification:

  • Wingspan: 1.66 m
  • Length: 1 m
  • Height: 0.49 m
  • Max take-off weight: 4.5 kg
  • Payload: 0.5 kg
  • Max speed: 80 km/h
  • Cruise speed: 50–80 km/h
  • Ceiling: 4 km
  • Endurance: 45 min
  • Range: 20 km
  • Max wind scale allowed for operation: 4
  • Operating temperature: -20 to 55 °C
  • Storage temperature: -30 to 65 °C
  • Deployment time (from storage to airborne): 5 min
  • Recovery time (from landing to storage): < 5 min

    • Swift 09

    Swift 09 is an electrically powered MAV of the Swift series, which like Swift III, is also manufactured by other Chinese UAV developers in addition to Yuhui. Swift 09 is of conventional layout with propulsion provided by a two-blade propeller driven by a tractor engine mounted in the nose. Specification:

  • Wingspan: 3.2 m
