Kontronik Pyro 800-40L Long Shaft Brushless motor

Its size already makes the new Kontronik PYRO 800 impressive: an outside diameter of 63 mm and a shaft diameter of 8 mm suggest the enormous power of the latest KONTRONIK motor. Its new designs includes bigger ball bearings and a screw-fixed motor can.

The Kontronik PYRO 800-40L is designed for 800 class helicopters, scale and 3D helicopters

Features:

•   High-quality Neodym material has been used for the magnets – heat resistible up to 150 °C
•   The winding has been made of an extremely heat resistant copper wire normally used by the aerospace industry. This wire can be stressed up to 300 °C
•   The rotating can additionally gets a precise balancing making the thin section bearing unnecessary
•   Adapted design for the stator
•   Perfected air stream through the motor and a radial internal cooling
•   Optimized magnetic circuit
