From his description is below max endurance/range speed and >near stall. Est. HP was around 52 HP at 25,900 feet. Actually, the best condition to be at would have been the speed that required the least amount of power, because power was the limiting factor here. The speed that requires the least amount of power is lower than the speed for best L/D, and is theoretically equal to best glide speed divided by 1.316. So Terry was probably not too far off the optimum speed at the light weight he was at. >If you want fuel economy and max endurance, fly at reduced power by >throttling back, to maintain best glide (L/Dmax), which is max >endurance speed. In RVs this is about 93-109 mph at SL. Assume a >nominal 100 mph IAS. Max endurance (L/D max) is good if you are just >trying to stay aloft longer but not real practical for going >somewhere. There seems to be some confusion between jet aircraft and piston aircraft performance. The two types of aircraft have different relationships between speeds for best endurance, best range, and L/D max. See: http://www.professionalpilot.ca/aerodynamics/performance/range_jet.htm http://www.professionalpilot.ca/aerodynamics/performance/range_prop.htm Max endurance is achieved at the speed that produces the lowest fuel flow, which means the speed that requires the least amount of power for a piston engine aircraft. The power required is equal to the drag times the speed (with a few conversion factors thrown in), assuming that the prop efficiency doesn't do something strange. So, the speed for best endurance on a piston engined aircraft is actually slower than the speed for L/D max. >If you want max range cruise, best mileage, you need to fly faster >than max L/D. This is true on a jet aircraft, but not on a piston engined one. With a piston engined aircraft, the speed for max range is the speed for max L/D, assuming that the engine produces the same specific fuel consumption at all power settings, and that the prop efficiency remains constant. In the real world, the engine probably is not quite as efficient at very low power, and the prop may be off its design point, so it efficiency may suffer a bit. These factors would lead to a max range speed a bit higher than speed for max L/D. In practice, the range vs speed curve has quite a flat top, so the range penalty to go a bit faster is quite small. People looking for max range will often target the speed that gives 99% of max range, as giving up on 1% of absolute max range allows the cruise speed to be bumped up quite a bit. >Optimum cruise is best range , approx best glide speed (L/Dmax) x >1.316 at sea level. Using the average best glide speed (L/Dmax) at >SL of 100 mph for a RV, Best range (SL) = 100 mph x 1.316= 132 mph. This is Carson's speed - the speed that gives the lowest fuel flow per unit speed. I.e. a good compromise.

That's less than a 1/3 of a cm as opposed to 1/3 of an inch when you are talking center to center distances. Matched pairs are very easy with metric sized belts. Very expensive with inch sizes. Your 30 1/2 " could be as short as 30 and as long as 31. a 77cm is 30.31 inches while a 78 cm belt is 30.71 inches.

I've thought about a pneumatic cleco tool, and since I live close to Boeing Surplus I might look for one there. I didn't mention Boeing as a source for air tools to the list since it doesn't help much if you don't live around here... There may be something similar in your area though worth checking out. Boeing has bins of Rockwell right angle pneumatic drills for $75 and rivet guns by the hundreds. I can see that the cleco pliers have lots of wasted travel when closed. I'm going to either find some different ones or modify one of mine... Boeing sometimes has boxes of them for a buck. Easy to experiment with. Sorry about my spell checker changing cleco to chloe. At least the header stayed correct...

I used it quite a bit today on my emp. Kit and it saved me a lot of fatigue from the cleco pliers.

I ordered the 3 part Sanchem 6100 system. Part C is a cleaner/activator. A&B get mixed 1:1. Basically, you scrub the parts with scotchbrite and part C, rinse and immediately brush on or immerse in the A&B stuff. I minute or two later, you have a pretty golden brown conversion coating. It looks exactly like my alondined conversion. I then applied AZKO two part epoxy over the whole thing. Mostly an all day project, but the results are beautiful. The really nice thing about the Sanchem is that it is not toxic or environmentally harmful. Judging from the color of the stuff, I would guess this is a permanganate that reacts with the prepared aluminum to make an AlMn04 coating over the surface. The folks at Sanchem, particularly Jonathon Filcher their technical guy, were very helpful. Will let you know in ten years if the primer remains intact. Anyway, took about the same amount of time as the alodine process, just a lot less toxic.

It's pretty easy to apply and clean up. And I am really happy with it so far. I'm using their seal #2 instead of primer on the internal bits. It puts a coating over the parts that is almost like lacquer or plastic and seems to be very durable.

From: "Eastham, Paul" --> RV-List message posted by: "Eastham, Paul" Hi list, I've seen several people warn not to overtighten NPT fittings, but how do you know if you've overtightened one? I was just struggling with my gascolator 45-degree elbow -- it started to snug up just past the proper clocking, so by the time it was back to the right position the torque was quite high. Toward the end I was wondering if I was bending the fitting rather than threading it in, though there is no evidence of this besides some scraped-off anodizing from the wrench. (yes, I used fuellube) I'm also willing to take the steel-fitting plunge (especially since I suspect I screwed up this fitting), but is there a dissimilar-metal problem if I use a steel fitting on the aluminum gascolator? Thanks, Paul RV-9A finishing ________________________________ Message 23 ____________________________________ Time: 11:04:10 PM PST US From: Jerry Springer Subject: Re: RV-List: Rude RVers? --> RV-List message posted by: Jerry Springer Finn Lassen wrote: >--> RV-List message posted by: Finn Lassen > >Apparently the following RVers visited Clearwater Airpark (CLW) today: >N699JB, N99PZ, N515L, N695LS and N628PV. > >If any of you are on the list, I'd like to hear your side of the story. > >Apparently managed to piss off a number of people including the flight >school owner at the FBO, not following published pattern at airpark, >violate St Pete controlled airspace and buzz the neigborhood below >minimum altitude, just as a meeting to appease complaining neigbors was >about to end.

I also know that most of them are or were on the RV-List. To characterize any on that list as RUDE is way off the mark. Finn I have to believe that you have the capability to look up who belongs to these airplanes and would have to agree with me. You have been on this list long enough to see most of them post here at one time or another. Jerry
