Back in the days of the Wessex. We had a Max All Up Weight of 13600lbs for hover and a Torque of 3200lb/ft
However we could go to 14000lbs with a running take-off. Simply start the aircraft rolling with forward cyclic and some collective, gently increasing collective to a torque between 2800-3000lbs/ft then as speed increased to over 20Kts as transational lift gently increase torque further to 3200lbs/ft and the aircraft became airborne.
