Okay, after waiting long enough to get up my nerve, here goes. I have a really stupid question. I have a Brison 3.2 (my first gasoline engine) that has a ton of power. It easily turns a 22x8 Pro Zinger at just shy of 8K rpm, and a 20x10 at 8300 rpm but as you might suspect it is very loud at those high rpm's. After reading a ton of posts about the noise issue, one thing keeps coming up. Keep the RPM's where the engine produces its best power, in this case around 6800-7000 rpm. I know when I throttle it back to this level the noise is much less and I understand why. My question is..... drum roll please....[:@] When you guys set your engines up to keep it at it's best RPM for power, how do you do it. Do you prop it until full throttle keeps it in the correct range, do you set your throttle servo EPA so the max. is in that range, or do you adjust the needles to get it there? I know this sounds simplistic, but I have my throttle servo end throw set so it can't exceed the RPM's I want it at. I really like the way my plane, Midwest 27% Extra flys with a 22x8 so I would like to keep my prop size at that. I also have a 21x8 NX prop to try next time and if it is quieter and flys as well, I may change to that. My goal is to lower the noise my plane is producing. I use throttle management quite well, but there are times when I need to push the left stick to the top! So far, no complaints, but I am afraid that it is just a matter of time.[X(]

Sorry if this is really dumb, but I just haven't seen this question asked before.
