-14 pole BL external rotor motor with Ø 28 mm

The new C28-14-1250KV was optimized by us especially for 4D flight.
The pole reversal performance is fast and reliable, it forms the perfect symbiosis between performance, weight and durability.
With our 4D propeller and 4D controller you get a powerful propulsion set that will give you a lot of pleasure.

But this engine is not only suitable for 4D flying.
It is also a perfect tuning engine for our BK Challanger Indoor Edition.
ROXXY® Brushless motors with neodymium magnets are state-of-the-art electric drives.

-High efficiency due to maximum copper filling level and use of high quality neodymium magnets.
-Smooth running due to large precision ball bearings
-weight saving by using a hollow shaft
