T-Motor Antigravity MN4004 KV400 Motor (Pair)

A pair of T-Motor Antigravity MN4004 KV400 motors for lightweight 4–6S multirotors on 13–17 inch props, such as aerial-photography quads and long-endurance mapping platforms. Each motor weighs 53 g with its lead, helped by an ultra-thin rotor machined from high-strength aluminium.

Key features

• Single thick copper strand winding to reduce energy loss in the coils

• Built-in ventilation path cools the windings, and each motor is dynamically tested for smooth acceleration and stable running

• EZO bearings and a finely balanced rotor for low vibration under camera payloads

• Up to about 1.29 kg thrust per motor on a 17×5.8 prop at 24 V

• One CW and one CCW prop adapter included with the pair
