No cracking? 160kt? Mate, the current Carson S61's just about run out of forward cyclic at 130kias
The blade performance is truly remarkable, but your mooted higher cruise speed is a recipe for disaster unless some serious re-rigging of the flight controls is achieved. As for the stress on the airframe, I'm not at all sure the old girl would take much in the way of significantly higher cruise speed?
