FPVCycle 16mm Motor - 3700kV

  • Sale
  • Regular price $17.99

This motor is unique in a few ways. First off, it’s sporting our new lighter prop shaft design, it’s got a 9x9 M2 mount so it will fit lighter style frames and the overall stator volume is higher than 1605 while weighing much less than it should. This motor is ideal for high powered 3” operation and low weight 4” crafts.

The goal of this motor is maximum power and control for a medium weight 3" quad. A taller stator with taller magnets are used for the high RPM control needed for small 3" props but a wide 16mm diameter with middling 3700kv is used to manage the heat dissipation of the motor in use. This is one of the most genuinely unique and interesting motors we've got in our lineup.

This motor is very powerful and 'notchy'. Please be sure to use a properly applied and appropriately sized capacitor.

  • 3” 3S-4S high powered craft with AUW >150g

These motors are special.

They have amazing power for their weight. IMO they work very well on 3.5inch with 5s lipo, or 4s lipo on 4inch prop, both work amazing

16 mm motor TOOTHFAIRY2 3”

This motor are very powerful.
Nice throttle response.
I think on 3s for 3” and 3.5” are very good and nice for TOOTHFAIRY2.

Amazed, as usual best micro motor in existence

Super happy with the performance economy and flight characteristics of this 16mm fpv cycle micro motor.
Paired with a 3.5” prop the flight feel is nothing short of amazing! Very happy with the improved low end feel and added altitude management characteristics.
Will be using again on other builds of this category.
Thank you for the development and research done on this 16mm platform!
