Oh Nick, where are you? Higher rpm is an easy weight increase for certification, but it costs you. Into wind, tail-rotor is fine, S76 does not suffer from lack of authority. For Cat A OEI, the pulldown from 107 to 90 will slingshot you to Vtoss with the right technique, with the wrong technique you just bleed everything away and fall in the ocean. Been a long time from the old A-models, and even the much better A++, but I do recall starting out at 107 and N1 limiting, so then beeping down, matching beeps, all the way to 100, or maybe even a little less. Position on the edge of the deck, hover, bounce of the wheels and a mighty pull to launch it over the side dynamically, even a little sideways so you didn't catch the tailrotor on the edge of the deck falling down trying to get Vtoss. Reject in the case of an engine failure was into the water, why we had floats, no external rafts. Damn those were the days. A sentimental way of saying that no, you don't get more power at a higher rpm. You store potential energy, that's all. Anyone else want to try fill Nick's shoes?
