TRADE UP Trade fair campaign

Recycle your old KOSMIK now and get 25% discount on a new COOL KOSMIK 250 HV




ROTOR live is a leading trade fair for KONTRONIK where we meet the users of our products personally. For this year's ROTOR live we have come up with something very special.Within the scope of a trade fair campaign we offer our users to exchange an old KOSMIK controller for a new COOL KOSMIK 250 HV at a special price.


The easy way to more power and integrated telemetry.


PYRO 850-24 P BM Competition

The already existing PYRO 850-24 P BM is now also available in the Competition version. A hand-wound winding with an even thicker copper cross section offers even more power and efficiency at high currents. Of course, an individual engraving is also possible with this Competition version.

The new SPIDER-SL 08-33

We are expanding our motor portfolio for UAV applications.

Especially for use in UAV applications, we present a new motor. The SPIDER-SL 08-33. The new motor is a disc motor, which has the advantage of light weight and high power.

DuoCool KOSMIK 300 HV and WaterCOOL KOSMIK 300 HV

Based on the COOL KOSMIK 250 HV, we have developed two variants with special cooling concepts. Thanks to these cooling concepts, these regulators crack the 300 A limit with ease.



The DuoCOOL KOSMIK 300 HV has a larger heat sink on which two fans can be mounted. Thus, this controller is best suited for e.g. Scale applications or bigger planes.The WaterCOOL KOSMIK 300 HV has a built-in water cooling system. The cooling water runs through the integrated cooling plate. Inlet and outlet have an outer diameter of 5.5 mm. This makes the controller very well suited for applications in boats.
