HGLRC SPECTER 1404 2750KV Brushless Motor

A light, well-built motor for tiny drones

The HGLRC SPECTER 1404 2750KV is a compact brushless motor engineered for micro drones and quadcopters. The 2750 KV rating gives strong thrust and quick response for fast, acrobatic flying, and it suits 2-inch tiny drones or 4-inch toothpick drones.

The rotor is a one-piece 7075 aircraft aluminium bell with an anodised two-colour finish, fitted with customised N52H curved magnets. The winding uses 200-degree high-temperature copper wire, and the stator uses imported Kawasaki silicon steel sheets for low losses. The shaft is alloy steel.

Specifications for planning

The motor runs on 4S to 6S, draws about 6.9 A continuously and has a maximum power of 155 W. It weighs 10 g, measures 19.13 mm by 12.25 mm and mounts with four M2 screws on a 9 mm circle. An ESC of more than 15 A is required and the recommended propellers are 2 to 4 inches.

The package includes five M2 x 6 mm screws and two M2 x 7 mm screws. Because the motor is so small, keep the screw length short so it never touches the windings.

Who it suits

Pilots building sub-100 g micro quads and toothpick drones who want a strong, durable motor with a quality finish.

Working with micro motors

Handle a 10 g motor gently: hold it by the base, never the bell, and keep hair, wire and tape strips away from the gap under the bell. Use fresh, well-balanced propellers and short M2 screws, and check the shaft nut after each crash. On a toothpick frame, keep the motor wires short and secure so vibration does not fatigue the solder pads.
