Abstract: An aerial vehicle includes an aerial vehicle body, and first and second rotor assemblies. The first rotor assembly includes a first hub coupled to first blades, and a first drive shaft coupled to the first hub via fastening features. The first drive shaft is configured to rotate the first hub in a first direction such that the first blades rotate in a first rotation plane. The second rotor assembly includes a second hub coupled to second blades, and a second drive shaft coupled to the second hub via fastening features. The second drive shaft is configured to rotate the second hub in a second direction opposite to the first direction, such that the second blades rotate in a second rotation plane. The first and second rotation planes are at opposite sides of the aerial vehicle body.
