Always press the trim tab switches in short one
second bursts. If pressed too long, you can
()
overcompensate, and potentially lose control.
DO NOT try to correct the situation by pressing
the other upper trim tab switch. Instead, raise
the tab slightly by pressing the appropriate
lower half of the trim tab switch.
