EMAX ECO II 2807 Brushless Motor

The EMAX ECO II 2807 (ECOII-2807) is a brushless motor from EMAX's ECO II series, built for 7-inch long-range and cinematic FPV quads. It is sold here in three windings: 1300KV, 1500KV and 1700KV; the 1500KV version is rated for 3-5S LiPo and produces up to 2450 g of thrust on 5S.

Key features

• 2807 stator (28mm diameter, 7mm height) gives a 7-inch prop the torque it needs without the weight of a larger 2810 or 3110 motor.

• 1300KV, 1500KV and 1700KV options: lower KV keeps current and heat down on higher-voltage packs, higher KV gives a livelier setup on fewer cells.

• ECO II series construction — EMAX's value line, sharing the mounting pattern and prop hardware of other 28xx motors.

• N52SH curved arc magnets and a 12mm EZO bearing for strong torque and smooth running.

• Pairs with 6-7 inch props and a 40A-or-higher ESC; mount on a 7-inch long-range frame.

Sold per motor — a quad needs four, all of one winding. Pick the KV to match your pack: higher KV means more RPM per volt, so lower-KV windings keep current and temperatures down on higher-voltage packs over long flights.
