Just setting here thinking on the threads on prerotors and wonder if anyone has tried to use a relief valve on their hydraulic prerotor. I think that you could set it so it would dump if the torque was too high as to cause blade flapping. If the dump releif was set right you could just leave the prerotor on and crank the engine right on up and still would allow the rotor to come up to speed in a controllable manner without the issue of blade flapping like in the Dragon Wings.
Any thoughts????????
