KendalSimpson Certificates/Ratings/Crew Stations: 2. "RE: Flying Figures with Fixed-Pitch..." 05-06-03, 12:42z  Hey Tom as you know I'm not flyin a Pitts but I'll tell you what I know/been told/experienced anyway. Just about everyone I talk to has no problem turning their Lycoming up to 3300 RPM. I have also been told that anything above 3000 RPM really isn't giving you much extra in the HP department and your just making more noise and wear on the engine so that's what I try to use for my limits. With my current engine/prop combination the only time I really get over 3000RPM at full throttle is in the vertical downlines. OK maybe when I dive into the box too. Basically the only time I'm not at full throttle is when I'm entering a spin (idle) or on a down line from a hammer/humpty/ etc... As soon as I'm headed straight down I reduce the throttle about half way and this keeps the revs in check. Be sure to do this smooth and I wouldn't go all the way back on it. I tend to think that harsh power application and reduction is just as bad as over reving. The moment I start the pull from vertical in comes the power firm but smooth. Now you have to remember that I'm hauling around 1100lbs empty wt airplane on 160hp. Needless to say I need all I can get to even fly in the same box as you guys. So for the Sportsman sequence in your light weight over powered (is there such a thing???) Pitts I'm betting you could set your power about 2500RPM in cruise, forget about it, and still fly a good sequence. Except for the spin of course and probably the hammer with 1/4 down. If your pulling out of loops and such the G loading should keep the RPM in check even at full throttle. Well Tom as you know you get what you pay for in the advice department so if you think this is worth anything send me a check. Have a blast and keep the dirty side up.
