EMAX ECOII 2814 730KV motor, ideal for FPV drones, designed to deliver reliable and efficient performance in applications requiring high thrust, such as large drones, aerial platforms or other electric propulsion systems.
It uses 4mm bearings and 18AWG power cables for the motor phases, providing an optimal combination of power, efficient cooling, and durability.
It works with 3–6S LiPo batteries and is compatible with 9 to 10 inch propellers, offering a wide range of combinations to adjust traction and consumption according to needs.
The motor has a low no-load current (1.1A at 10V), which makes it efficient even at low speeds. At peak it can reach a maximum current of up to 50A. In combination with various propellers (such as Emax Avia, HQ or Gemfan – all with 3 blades), the motor achieves thrust forces between 280g and 3300g and an efficiency of up to 6.49 g/W in moderate load regimes.

Use:
The motor is firmly fixed to the frame using M3 screws. VERY IMPORTANT: When tightening the screws, BE VERY CAREFUL that the screw does not touch the motor stator (winding), as this may cause a short circuit in the winding.
Connect the power wires (18AWG) to the ESC, following the ESC's instructions and ensuring proper soldering. If the rotation is in the opposite direction, you can reverse the motor phases (wires) to get rotation in the desired direction.
Choose compatible 9"–10" propellers, preferably 3-bladed for a balance between efficiency and traction. Both the motor-to-frame mounting bolts and the propeller mounting bolt are included in the kit.
Use a LiPo battery between 3S and 6S. Check that the ESC can handle the maximum voltage and current required.
Testing: Before flying, test the engine operation at low speeds to check for unusual noises or vibrations, and especially WITHOUT PROPELLERS!
Ensure that the motor has adequate airflow in intensive applications.
