| Thanks Wayne,
I use an OS 91 with a KSJ muffler in my CS which I use for FAI, and I'm pretty sure if I had an ID1 curve like your's she'd overspeed and the conrod would probably decide to retire out the side of the casing  .
I do my loops in ID1, and if I have to 'pump them out' (ie go further into negative pitch than I normally would) to get them symmetrical, you hear the engine distinctly change note because it's in it's lower rev range. curve like yours, or a Governor would fix that though I suppose.
In the rolling stall turn + 540 stall turn, do you have different rudder rates, so that you don't 'overshoot' the 180 turn at the top of the rolling one, and then have enough tail power to do the 540 quick enough on the other side?
