Park 400 Brushless Outrunner Motor 740Kv (EFLM1300)

Park 400 brushless outrunner motor, 740Kv, is a compact external-rotor powerplant designed for small 3D and park-flyer aircraft. Its slotted 12-pole outrunner design and external rotor eliminate the need for a gearbox, helping keep weight down while delivering quick, responsive power for models in the 10–20 oz (280–560 g) range. It serves as a direct replacement for Speed 370 and Speed 400 configurations and ships with a motor mount, a prop adapter, and gold-plated connectors to simplify installation.

To complete the setup, pair this motor with a 10–20A brushless ESC and a 10x7 to 12x3.8 prop, powered by a 7.4V or 11.1V Li-Po battery in the 860–1320 mAh range. The external-rotor design saves weight and promotes quiet operation compared with gearbox-driven systems, helping maximize performance for lightweight park-flyer and small 3D models. The included motor mount and prop adapter further ease mounting on compatible airframes.
