The Emax Eco II is a series of solid motors at an affordable price. The motor is very well made. Even in this price category, it uses 7075 alloy and round N52 magnets, which are normally found in the best motors. The shaft is steel.
The 2004 3000Kv version is mainly suitable for 3" drones using a 6S battery and 4" or 5" ultralights using a 3-4S battery. Thanks to the t-mount (propeller mounting on 2 screws), the motor retains a low weight of 16.4g.
