Reason I'm asking is on the fb video it went up into hover first, during the transition the tail dipped slightly only to be instantly corrected.
Just wondering if trim is some function of the cyclic control system.
I could google but would rather hear from the horses mouth

PITCH AND ROLL TRIM ACTUATORS
Pitch and roll trim actuators are installed in parallel with the cyclic stick below LH forward cockpit floor. Trim actuators have full travel authority on the pitch and roll control lines.
Trim actuators can be overridden by pilot commands via a spring-clutch. Actuators are operated by pilot commands or by the AFCS. They convert the command to a mechanical output.
