ElectrotorSloMo_Hub

Electrotor-SloMo ~ Rotorhead - Hub-A

Overview:

Pitch bearing are mounted outboard of the electric motor and the hubs are at 18" centers.

An absolutely rigid rotor; hub and blades c/w torque-pitch coupling that effects the full span of the blades.

Picture of Partial Mockup: Motors rotor that is shown in the picture is not part of this assembly.

The hub is shown inverted

The F&P electric rotor will be seated down flush with the hub of the aerodynamic rotor.

In the gap between the black rotor and the blue hub will be a large diameter elastomeric bearing.

For information on this specific design see the item marked with

below.

Pros & Cons:

Pros;

xxps

Cons;

The connection between blade and hub may be weak.
