I plan on 5200 for my max RPM, so am just doing the math for 5200/2=2600. Power wise,5200 can be reached easily enough even with the non-turbo engine. The trick is how much prop can one spin at a tip speed of 2600. Warp should be able to tell us what pitch RPM combo is best. Just read the look at this below paragraph. So your saying 3000 for the tip speed, interesting. 5200/1.8 would give almost 2900 and 1.7 would turn it 3058 at 5200 engine speed. What pitch were you at? Isn't 3000 super sonic though? Rick -----Original Message----- From: owner-kitfox-list-server@matronics.com [mailto:owner-kitfox-list-server@matronics.com]On Behalf Of kurt schrader Subject: Re: Kitfox-List: Reduction drive (out put module) ratio --> Kitfox-List message posted by: kurt schrader Rick, What is the actual HP output of your engine? I think it is a little more than my 143 hp - something right about 150 hp? Lance gave me a 2.23:1 ratio for mine. If you have more hp, you could use a little lower ratio based upon that, but I think the 2:1 might be too low. Then again, take a look at this site: >http://www.bewersdorff.com/computational/prop.html< Pluging some numbers in, your 2:1 ratio comes closer to reaching the optimum tip speed, which it says requires 3,000 rpm or more from the 72" prop around our range of speeds and altitudes. We best not run 3,000 prop rpm without Lance's backing though. But I do know that the accelleration picks up very noticably when I take off at max rpm, rather than even a few 100 rpm lower. Interesting? I was surprised at the results when I first tried this. I bet the prop would be noisy.

I take it out when I'm flying alone or if I have a pax who doesn't want to do any flying. Dave ----- Original Message ----- From: "kurt schrader" Subject: Kitfox-List: Re: Stick movement --> Kitfox-List message posted by: kurt schrader Do not archive. A friend of mine was talking about an F-16 crash a while back. It was a 2 seater and the local #1 pilot was taking the doctor up for a ride. Seems that the doctor kept hitting the side stick with his leg. When the pilot yelled "Get off the controls" the doctor thought he meant the rudders and pushed his legs even higher and wider causing the plane to roll over into the ground. The strange thing was that the pilot had a switch where he could cut off the other stick and he never switched it off. Of course our sticks are not electric and tied together so we can apply force to the other one too. I just worry about if I'll need all the controls one day. Went to the local flying club meeting last night. They were wondering how high you could bounce a tail dragger before you went around. Some claimed of 20 foot high bounces... Now I don't feel so bad....

Maybe after I get Lance to rebuild it, he'll give me an upgrade too. I bought the smaller turbo just in case it gave me a little more TBO. Probably why I get the lower hp, but I think Lance dropped this option. Like you mentioned, it may be the valves that go first. I still need to see which size I have before ordering the SS ones from you. Too much to do right now. The first consideration is the strength of the prop. I don't know if the CAP 140 should ever hit 3000 rpm in practice. I know Lance builds in a big buffer, but we don't need to test it without knowing it is "normal". According to that web site, "Prop Tip Speed Calculator", 3000 prop rpm is well below supersonic for 72". In fact, it is just barely up to the best power range of 0.88 Mach when we get up to 140 mph true at 5,000'. 3,150 is the highest rpm we should use for 0.92 Mach there. Some seaplane operators use 3000 rpm on their 76" props. That is within the best usable range, but it sure is noisy! If we pushed the rpm up there, I think ours would be more efficient, but noisy too. Again according to that site, you could swing a 85" prop at 2600 rpm. Not do-able for us without Storch gear and big GB bearings. Up to 17,000' you can still use 3,000 rpm at 140 mph true for our 72". Those are at standard day temps. (It works density altitudes in for you too.) So I was using 3,000 rpm as a safe tip speed range. You would not likely take off or use that rpm at 17,000'. Or at least I don't plan to, but it could be done with our planes. :-) My dyno readout shows a max of 6,000 engine rpm and 2650 prop. That is over 1,500 egt at that more remote egt mount Lance uses. Best hp was 143 at 2580 prop or 5750 engine rpm. My torque curve flattens out by 3350 engine rpm, so above that is good enough for cruise, I figure. BTW, my max torque is 297. What is yours? 312 or so? If I use 5200 rpm as max I lose 11 hp. The first takeoff by my friend, who does his homework, was at 4,000 rpm to give 100 hp. That is what he has and he wanted to start from a known point to compare with mine. Lance's last limitation sheet to me gives wide limits. Max of 5800 rpm for the turbo and max continuous of 4800 rpm. I set the gage pointer at 5600 max and redlined it there. I had been using less than max for takeoff until my last takeoff. The accelertion difference was very noticable, as I said, from just a few 100 rpm change. More hp and more efficiency? I understand that you are not using Lance's higher egt limits either. His sheet gives a green arc to 1575 and a max of 1600 degrees. Overall, I think that we are not running the prop tip any where near most efficient speed, but that we are all enclined to use safer rpm limits. Same with the other limitations. We are all trying to stay under what Lance tested at, even at a loss of hp. Use what we need and not what we have until necessary. I agree that you should talk to Warp and Lance too since he makes the hub, before increasing the prop rpm. If 3000 works out to be safe, only then regear to that. I suspect that Lance gave you the higher gear ratio just to keep that prop rpm down while absorbing your greater torque.

My wife was real apprehensive (read "chicken") to go flying with me in a plane with only two seats. The "EXPERIMENTAL" blaring at her as she opened the door really did little to reassure her. She pretty well knew that the plane was "safe" as I flew it home all the way from "Down South" w/o any problems. Finally, I got her interested in viewing some of my pilot training DVD's. This got her interested as well as causing her to purchase a copy of "The Right-Seat Handbook" during a trip to the pilot shop. I didn't push her and finally she gathered up her courage, asking one day to go for a ride. When we got to the plane, I showed her what the flight controls did, how they worked, including the panel instruments, before even getting into the plane. Once I got her comfortable with the plane, it was great. She was really impressed with how fast we got up and away. She is used to Piper Archers, Sixes and Caravans so the little Fox was very different for her. After a lazy climb to 2500AGL, I did some "S" turns, and some other easy turns. I offered her the controls, and to my (pleasant) surprise, she gave it a try. It was remarkable how well she did, she has a real nice light touch on the controls and used the rudder almost instinctively. Nice, well coordinated turns. (thanks SS for adjustable pedals!) Anyway, she doesn't hesitate anymore when I offer a ride. She's looking forward to this summer and some real exploring! (I suppose I'll be paying for her flying lessons, soon.) I go through the flight control/panel lesson now with everybody. I just consider it as part of my PAX briefing now and it keeps me sharp. Most friends ASK if they can try her out once trimmed out and cruising before I can offer so I figure this is a good thing. They couldn't enjoy this special thrill if I took out the right stick. I'm hardly an "Old Timer", but if it wasn't for all the people that let me take the controls over the years, I would have spent a LOT more time/money on getting my certificate and would have missed out on all those thrills.

So while I agree the Speedwing Avid was a little hotrod, we're not really comparing apples to apples. My purpose in asking the question about whether or not the Kitfox IV Speedster could really do 130-140 mph was to find out if anyone is actually doing it with their airplane. Apparently there are some owners that are doing numbers that are close, but I haven't heard of anyone actually attaining the numbers claimed by the writers and the factory (yet).

Very few will pitch or for that matter prop for just the speed. Blue Skies!! John & Debra McBean "The Sky is not the Limit...

Nothing in common means we (I) can't compare the two. Sorry. Glad to be part of the discussion and will help when I can. Surprised my buddy from Mikado, Mi. didn't jump on me for that fau pax! Hey, Darrel, you alive out there? NO names mentioned here.

I got an outside air temp probe, but didn't get the fuel flow monitor or the altimeter- VSI. $607 + $10 shipping. Hope it's a good as everyone says. Randy - Series 5/7 - 912S - this spring!!!
