Not cool to not give credit.

Recommended props when using 3 cell Lipo batteries:

The GWS EP9050 produces 30 ounces of thrust at 17 amps. Use with caution

The GWS EP8040 produces about 24 ounces of thrust at 12 amps. Best all around prop for this motor.

The APC 8x4E produces 25 ounces of thrust at 14 amps.

The GWS HD8060 produces 22 ounces of thrust at 17 amps. Use with caution

The GWS EP7035 produces 15 ounces of thrust at 7 amps.

The APC 7x6E produces 19 ounces of thrust at 12 amps.

Recommended props when using 2 cell Lipo batteries:

The GWS EP1170 prop produces about 21 ounces of thrust at 15 amps

The GWS EP1060 prop produces about 18 ounces of thrust at 12 amps.

The GWS EP1047 prop produces about 19 ounces of thrust at 13 amps.

The GWS EP9050 prop produces about 16 ounces of thrust at 10 amps.

The GWS EP8040 prop produces about 12 ounces of thrust at 6.5 amps.

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.
