Description:

EMAX CF2805 Outrunner Brushless Motor

The Emax CF2805 is a 0.9 ounce, 2800KV direct drive outrunner motor that works well on small pusher jets, flying wings and a wide variety of small foam models.

The Emax CF2805 will produce up to 15 ounces of thrust using a GWS 7035 prop, or you can get very high speed using an APC 6x5.5E prop.

Good battery choices for this motor include the 7.4v 1000 20C and 7.4v 1300 20C Lipo batteries.

We recommend using the ZTW 20A ESC or EZ Flite 20A ESC with this motor.

To mount a prop, you will need a 3mm Prop Adapter, or 3mm Prop Saver.

MOUNTING OPTIONS: A firewall mount is included, and an Aluminum Stick Mount (for models with 10mm sticks) is available in our store. Always check the tightness of all motor set screws and motor mount screws when installing motors. The set screws require a 1.5mm Allen wrench. The picture below is for reference only. NO STICK MOUNT IS INCLUDED.

Recommended props when using 2 cell Lipo (7.4v) batteries:

The GWS EP 7035 prop produces about 15 ounces of thrust at 13 amps.

The EMP 6x3 prop produces about 13 ounces of thrust at 12 amps.

The APC 6x4 speed 400 prop produces about 12 ounces of thrust at 13 amps.

The APC 6x5.5E prop produces about 10 ounces of thrust at 15 amps.

The APC 5.5x4.5 prop produces about 10 ounces of thrust at 12.5 amps.

The APC 5.25x4.75 prop produces about 9 ounces of thrust at 12.5 amps.

The GWS EP 5030 prop produces about 9.5 ounces of thrust at 7.5 amps.

The above data is a result of our own testing using fully charged Lipo batteries.
