Embodiments provide scissoring mechanisms for a vertical lift fan of an electric aircraft (e.g., a vertical take-off-landing eVTOL aircraft) where the blades of the vertical lift fan can be opened at almost zero speed. Exemplary scissoring mechanisms have position locking features that keep the collapsed blades in the low drag orientation once closed (e.g., in the stowed position). As a result, the scissoring mechanisms do not cause large impulses during opening and closing that cause large stresses and noise. In addition, the scissoring mechanisms provide an opportunity to check that the fans are opened properly prior to spinning them to the full operating speed. The scissoring mechanisms may not require an extra actuator, and rely on the propulsion motor.
