MAD 4006 EEE 380KV Brushless Motor

The MAD 4006 EEE is a 380KV brushless outrunner for long-endurance multirotors and heavy-lift UAVs on 6S LiPo. Weighing 72 g, it produces up to 2.2 kg of thrust — a 30.5:1 thrust-to-weight ratio — on 13–16 inch carbon fibre propellers, the low-KV, high-torque combination used on mapping, inspection and cinematography airframes built for flight time.

Key features

• Recommended working load of 500–1000 g per motor, with 2.2 kg maximum thrust in reserve.
• Efficiency above 81% for more flight time per pack.
• Rotor balanced to under 5 mg to keep vibration away from the flight controller and camera.
• Open-body design for passive cooling.
• Supplied with a propeller plate, adapter ring, 3.5 mm bullet connectors, heat-shrink and screws.
