This Variable Pitch Prop hub is designed for airboat, hovercraft, Light and Ultralight Experimental aircraft etc. DC electric motor with planetary gear is built in the hub.
It is powered through a system of carbon brushes and contact rings. KOOLprop and Kievprop type blades can be used with this hub. More info about
KOOL blades HERE. You can install and remove them by yourself.
Digital Control System (aircraft type) consists of Control board and ECU. The Control Board is used for programming, adjustment and displaying
current blade pitch. 3-preset propeller positions (MIN, NEITRAL, MAX buttons) for example takeoff, cruising, feathering or reverse;
manual control (Step+ and Step- buttons) with pitch degree monitoring.
It is possible, if necessary, to switch off the Main Digital Control System and use Emergency control circuit (rocker switch) as a back-up manual pitch control.
The prop diameter 60-80″. Can be used for pusher-tractor config, with CW and CCW rotation direction blades, as a reversible propeller.
