Leopard Impeller 90mit Brushl Graupner 1371.90.8B1

Leopard Impeller 90 mit Brushless Motor Graupner 1371.90.8B1 Description
The Leopard impeller series is marked by very high manufacturing quality. The milled aluminium impeller housing provides for very quiet, precise running behaviour. The impellers are delivered balanced and ready to install. 3.5-mm gold contact connectors are already soldered to the built-in 4-pole brushless motors. The inlet lips on the impeller housings arescrewed on by means of a left-hand thread and can be uninstalled depending on the use. The cables are routed through the thrust tube and into the fuselage via an aerodynamic cowling installed on the motor housing. The five-blade rotor is made of high-strength, impact-resistant plastic and covered by an aerodynamic aluminium cap.
