Perhaps the collective wisdom of this group can set my mind at rest. In piston aircraft engines, the concept of running over squared MP vs RPM has been heavily questioned to the extent that some suggest running at full throttle all the time and controlling the power output via RPM (within reason). The thought is to, I believe, eliminate the induction restriction of the butterfly valve increasing the efficiency. Now we have a rotor spinning, a gear box gearing and a propeller propelling. Does this concept hold true for the rotaries. What are people doing in terms of setting power after take off (full throttle max RPM). My enquiring and rotating mind wants to know.
