  • 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.

    Amazing service

    I accidentally ordered the wrong ones and emailed for support to get the order canceled and reordered. Josh responded by saying he fixed my order so no need to cancel and that the order was processed to ship the same day! Amazing experience and great quality

    Bad @$$ Motors!

    If you’re looking for super smooth, reliable, light motors for your 5” or 6” (some even run them on their 7”s) and you don’t mind spending a few extra bucks then you’ve found the right motors. I run these on both my Apex and AOS setups and I’m in love with these power plants.

    Took the advice of a fellow pilot

    After 5 years of flying 5s I decided to level up to 6s. An with doing so needed to upgrade my motors. So before I set out to find a motor that I thought looked good, I decided to ask the options of like-minded pilots on DroneNation. Glad I did! IvoryViking showed us that these Fpvcycle imperial motors are more than just thee most durable but they also fly amazing! Low throttle control is perfect,mid throttle is a sweet zone, an High throttle is so easy to control! I fly this motor with s5 ethixs prop an have an average flight time of 5+minutes of aggressive freestyle on a 1380mah. 6+ minutes while cruising around on 1400mah. And that is with a GoPro Hero8!! This is on a 5" source one build.
    My first pack I was simply surprised at how well they made the quad fly. You can definitely see the amount of time put into the construction of these motors. The bell thickness is twice as thick of a xing pro series motor. I'll break an arm before I break the motor! Don't let the size of this motor think it's heavy, it definitely makes up for it in power an control.
    Now that I'm hook to the power of 6s , planning to build a armattan chameleon Ti 5". And think I might buy another 4 of these. We shall see next week on payday what the wife says ;)
    I'm a very happy customer!
