A few years ago their was a local chap who did just that. Not only did he kill himself but he broke a perfectly good Spitfire which had nothing wrong with it. (Except that the engine had stopped of course) Cheers Pat pj.ladd@btinternet.com Do not archive ________________________________ Message 2 _____________________________________ Time: 03:13:02 AM PST US From: "PATRICK LADD" Subject: Re: Kolb-List: Re: best lift to drag speed. --> Kolb-List message posted by: "PATRICK LADD" <> Hi John, Yes, I agree. The whole question is pretty acedemic from 1000ft. Just fly the plane.

Before I deal with anybody when I am selling whatever , the first one with cash or certified check ( confirmed at the bank) is the new owner. They can leave a deposit , but if someone else shows up with the bucks , it is gone and the deposit is refunded. Needless to say , I have never had anyone give me a deposit...I have volunteered to deliver but now think that is a mistake....let the new owner experience the "thrill " of getting a new plane home intact ! Don't worry, sounds like a good machine and it will sell....

No, best L/D is faster than minimum rate of sink. Please draw the parabolas I described and see. 2. It'll generally be close to that, but depends on the prop. In fact, with the drag of an idling prop, the best L/D speed decreases over that of the airplane with no prop - so in flight testing, the power condition is pretty important. 3. It's based on the whole airplane and engine and prop combination. The two major factors are overall drag and wingspan. In fact, knowing overall drag, wingspan, engine and weight, you can make a good estimate of any airplane's performance. 4. Oh, yeah! Absolutely. Full agreement here. 5. With a power plane, getting close to L/D is good. Not stalling is even better. No need to worry about minimum sink speed unless you're soaring. Dave Paule Boulder, CO FSII =+=+=+=+=+=+ David, I'm sorry but you seem to have lost sight of what has been said. 1. L/D max gives you minimum rate of descent when power is reduced. 2. L/D max gives you best rate of climb with power applied. 3. L/D max is based on the airfoil not on the engine/prop configuration. 4. L/D max is determined by flight testing and varies with several variables. 5. Any speed above the stall speed is good, but the speed that gives you L/D max (minimum sink) is a good number to remember.

Rick Neilsen Redrive VW Powered MKIIIc Did I hear something about Seafoam? Hey, in all seriousness, I had Seafoam soaking in the front cylinder of my 447 for 3 weeks because the weather has been terrible here on weekends. I got concerned one night, 2 weeks ago, when the temps rose to the 70's during the day after being at freezing during the evening hours. The outside of the engine was sweating with the warmer air when the garage door was opened. I got concerned whether the Seafoam would protect the cylinder as it gets filled up with the stuff when I give it the treatment. If any water gets inside, the rings could rust in place if the lube doesn't protect it. Last Sunday, before starting, I moved the prop to check for any kind of resistance and found none. I proceeded to start the engine and blow out the Seafoam. It blew the usual white smoke for 5 minutes. Now both cylinders are whistle clean as I previously did the rear cylinder 5 weeks ago.
