The EMAX ECO II Series 2807 1700KV is a next-generation brushless motor with a redesigned, rounder structure and reinforced components. Upgraded N52SH arc magnets improve torque and give a smoother throttle response, and the motor is designed for both freestyle manoeuvres and extended-range FPV missions.
The bell has a new, rounder shape with reinforced connection points for added durability, a mirror-polished finish and a large 12 mm EZO bearing for super-smooth performance.
The motor has a KV rating of 1700 RPM per volt and is rated for 14.8 V (4S) at 15 A, with a peak current of 50 A. The stator size is 28xx, the maximum thrust is 2100 g on 4S and the recommended propellers are 6 to 7 inches. It uses a standard 19 x 19 mm mounting pattern.
Size your ESC for the 50 A peak, choose a 6 or 7 inch propeller that suits your battery, and use thread lock on the mounting screws. For long-range flying, a large low-pitch propeller and a gentle throttle style will keep current low and flight time high.
Pilots building a 6 or 7 inch long-range or cinematic quad on 4S who want a durable, smooth motor.
Long-range flying rewards efficiency, so start with a large, low-pitch 7 inch propeller and check the hover current on the bench. A good target is a hover current low enough that the motor stays cool to the touch after a two-minute hover. After that, measure the full-throttle peak against the 50 A rating and choose an ESC with a comfortable margin above it.
