Emax GT2815/05 Outrunner Brushless Motor

The Emax GT2815/05 is a 4.0 ounce, 480/.10 class, 1500KV, 530 watt outrunner brushless motor designed for high speed models, and for models where prop size is limited to 8 or 9 inches.

The Emax GT2815/05 is designed for use with 3 cell Lipo batteries, and the APC 8x4E prop is a good all around choice for this motor. For maximum speed, the APC 8x6E prop can be used, and for maximum thrust, the APC 9x4.5E is a good choice.

We suggest using a 3 cell Lipo battery that is rated for about a 70 amp continuous discharge (or more), such as an 11.1v 2200 35C to 11.1v 3300 35C.

We recommend using a 50A to 60A Electronic Speed Control (ESC) with this motor, depending on what prop is used.

The GT2815/05 comes with 4mm male connectors installed, and female connectors are included for your ESC. 

MOUNTING OPTIONS: The GT2815/05 can be mounted in front of a firewall using the included X mount and rotor end prop adapter. It can also be mounted behind a firewall, using the included 5mm prop adapter to mount a prop on the motor shaft. 

Propeller data for the GT2815/05 using a 3-cell Lipo battery: 
It's a good idea to balance all propellers with a Propeller Balancer before using them on this motor.
Rotating propellers are dangerous. Please stay clear of prop and wear eye protection.

APC 9 x 4.5E: 62 oz thrust at 48 amps (530 watts)

APC 8 x 4E: 50 oz thrust at 36 amps (400 watts)

APC 8 x 6E: 49 oz thrust at 46 amps (500 watts)

Please be aware that the battery used can make a tremendous amount of difference in the performance of brushless motors. The above data was obtained using batteries in good condition that were fully charged. Thrust and amp draw may be less with the use of batteries rated at lower amp output, and slightly more using batteries rated for higher amp output. Other factors, such as ESC timing and variations in actual motor KV can affect the performance of brushless motors as well. We recommend the use of a Watt Meter to test the current draw of your particular power system, especially if you plan to use a prop that pushes the motor near it's maximum amp rating.
