  • High performance: 1870kv with 6S 1100-1400mah and AUW below ~745g
  • Med-High performance: 1870kv with 5S 1550mah and AUW below ~745g
  • High performance: 2150kv with 5S 1200-1600mah and AUW below ~745g
  • Cruising: 1870kv or 2150kv with as little as 4S 1300mah or larger battery
  • Any of the above setups at a lower AUW is going to perform significantly better.

This Motor Pairs Well With:

This motor has been very carefully optimized for use with 4.8-5.2" props on full 5” quads but of course you're welcome to use them however you like.  The most notable performance benefits are improved low throttle management and easier altitude control compared to typical 5” motors.  Otherwise, it is a powerful motor that performs exceptionally well on any general ~5” platform.

These motors are designed to perform well with the increased load of a Hero camera (~710-740g AUW) but if the quad has an AUW below ~680g, the performance is exceptional.  It is recommended to run no less than 5S 1200mah or 6S 1050mah in order to optimize battery performance.  Under high speed/high stress flying, 5S 1250mah and 6S 1150mah minimum is recommended.  We recommend the highest C batteries available from any given company.

Your prop choice is entirely personal however the recent trend is to use lower load props that continue working well into the higher RPM range.  Our favorite props are the Gemfan F4S and Gemfan 5226. The 5226 is specifically designed to provide better hover efficiency and higher cruising speeds which is often what is required for filming action sports. You do give up a small bit of response to run the larger 5.25" prop that is the 5226. Running a prop larger than 5.1" also begins to dilute the improvement in low end throttle feel of the motor. The F4S prop is strongly encouraged to try.

We’ve been working on this motor for well over three years and spent a lot of time and money on development.  We won’t be disclosing the all the intricacies of the motor.  Compared to a typical 2306, this motor stator is ~20% larger by volume and has ~20% greater surface area.

    Just pure fun

    These motors are really well made, perfekt winding quality, and good looking.
    They fly just perfect, in terms of performance and torque. There is a downsinde if you are not in the US, shipping and Tax is a thing. But still recommend them. Thumbs up.

    Too good

    Used to running budget motors on my 5 inchers. After the first flight with the 25 mm I realized I'm never going back. The added smoothness and authority is unbelievable.

    Blowing motors suddenly.

    I have 2 identical 5 inch drones. The only difference is one has the old bell design, and the other one has the new unibell design. The motors on the old bell design run much cooler and I don't think I have blown 1 motor. With the new design I had to replace an esc and 3 motors( within 2 months) . These motors fly just as nice as the original but they run much much hotter. Currently trying to filter and tune out heat.
