I like to fly slow and gawk, that's why I built a FireFly ultralight. I normally cruise at 5,000 to 5,200 rpm which translates into 50 mph to 52 mph. Sometimes at 4,800 rpm if interested in a particular place and want to enjoy. I can go faster, but don't need to. Flying for pleasure, not to get somewhere. This is with an open cockpit, probably could do a little better with a full enclosure. Also, the number of takeoff's really increases the fuel burn rate. Fuel consumption goes up in mid summer with the loss of air density.

Last night, after I went to bed, I remembered what I was trying to think of about the comparison of rib stitching and fabric rivets. It has to do with grip and pull. Wooden rib caps are usually flat and wide. Rib stiching does a good job of covering the same width of fabric and reinforcing tape as the width of the rib cap. On the other hand, rib stitching a 5/16" tube presents a problem or two. First, if we grab the same amount of reinforcing tape and fabric as the width of the rib, the rib stitch will pull the fabric down around the round rib cap. Second, if we grab the apex of the round rib cap, we may not have sufficient material to secure it correctly. I may be wrong, but that is what was running through my head when I went to sleep last night. Now, which system is quicker? Probably depends on the operator. However, it doesn't take long to mark and drill the rivet holes before the fabric goes on. Then a quick once over with the pencil soldering iron to burn through the reinforcing tape and fabric. Setting and popping the rivets is quick. All this requires one man. I have very little rib stitching experience. I stitched the rear longerons of the mkIII fuselage in the area of prop drumming. Was made more difficult because I had already installed the fuel tank and most of the stitching was "blind" stitching. Don't want to do that again. Take care, john h mkIII ________________________________ Message 9 _____________________________________ Time: 07:34:30 AM PST US From: "Richard Pike" Subject: Re: Kolb-List: wings Correct on all counts. If you are going to rib stitch 5/16" tubing, you want 1/4" wide reinforcing tape. Perhaps the most important thing is your mentioning that rivits take one man. If you are going to do it by yourself, by all means, use rivits. If you have the luxury of a companion to talk to while you poke the needle back and forth from one side of the wing to the other, with a cup of coffee sitting on the stool next to you, rib stitching becomes more appealing.

I have covered the upper half of one wing, and that was about 4 years ago. I'm actually going to uncover it---and recover with new materal all the same age on all surfaces. (I haven't finished building the plane, yet. but soon, I hope) As far as I know, maybe rivets are ok, I've never seen a riveted fabric wing. But I felt stitching would give me the ability to increase the attach points, and make a slightly smoother ridge. Not here to criticize rivets, just chose my own preference. I can tell you one thing....rib-stiching by yourself is a joke. Running in circles around the wing is a diizzying nightmare. You REALLY want to find a competant helper if you are going to rib-stitch. But, if I can't find a helper, then I'm going to rivet!!!! Oh, BTW, Dondi recommends the narrower reinforcing tape than the 1/2" wide stuff we're normally supplied with, for stitching. Yay!!!! Yesterday, I went down to the local building dept. and picked up the permit for my (airplane) shop. Picked up the pool permit on Wednesday. So, officially today I begin tractor work on my pool and shop. (I've been a concrete and general contractor for 30+ years) Have a pleasant day all. I, for one, hear a tractor calling my name..............Mike in Utah FYI I saw on the weather this morning, we in St. George are about double Salt Lake City's temp. We should get to 59, they'll see 31 degrees. We're kind of the balmy part of the state.....much like Vegas weather...........gotta go. _________________________________________________________________ Get Hilary Duffs homepage with her photos, music, and more. http://celebrities.live.com&ocid=T001MSN30A0701 ________________________________ Message 11 ____________________________________ Time: 08:16:11 AM PST US From: "Mike Welch" Subject: Re: Kolb-List: wings For what it's worth... John H. has some important points re: stitching, and bunching of tape, etc. And as I already stated, stitching is really a two man job. Although I intended on rib-stitching, my mind can easily be changed!!!! My only question is: Are the rivets very noticable when the wing is finished??? If they aren't, then I will go back to the rivet method. It will be a LOT less work, that's for sure.

Not too bright but it worked great. First cut it out with a jig saw and cutting oil (the type you would use with a drill press). Without the oil you could only get about an inch of cut. Then I tried the 1/8" instrument panel that comes with the Extra's pod. That plate fetched up on the bit jumped in the air fell back on the bit busted it and bound up stopping the motor. The only thing I could do was yank the power plug. Believe it or not all was saved except the bit ofcourse. I finished it with gloves on. If you have a router table and like your fingers use a clamping system.

The previous owner cut a new IVO 3-bladed prop down to 54" diameter. Performance would probably be better with a new 62" 3-bladed Ivo, but I'm not sure it would be worth $550+ to find out. I have a used Ivo Left hand prop in great condition (3 blades only) if someone wants to trade with me I can find out. This Spring I will do more flying, testing, and tweeking to try to determine its performance. There is also another Firefly owner about 90 miles N of me. Maybe we could get together for a race to 5000'. I have seen his plane fly (with 2-bladed Tenessee prop) and I think he would win. BTW, I really like the oil injection. It saves a lot of mess and now if I don't use my UL fuel fast enough, I can dump it in my car. I can also buy Avgas on a XC without the mess and worry of mixing correctly. > | > My Firefly has a 503 DCDI. > > > Earl: > > I get a rush flying a 447 FF.

After I get everything the way I want it and the weather warms up, I'll make some quantitative tests. If it doesn't do at least 1000fpm ROC with the existing prop, I will probably go to the longest 3-bladed prop that will fit in the trailer (I'm hoping 62"). >From what I've heard, 3 bladed props give better climb and 2-bladed better cruise. With the FF climb performance is not a problem so I'd rather have a 2-bladed prop to reduce weight and increase cruise. Unfortunately, if need to go to a new one I think space requirements will dictate a 3-bladed prop. Thanks, Jim -------- Jim N.

The few small curves I needed I did with short cuts and a belt sander. I need a band saw! -Dana -- -- People in cars cause accidents.

All other things being equal, a 2-blade prop is more efficient (a 1 blade is even better, but obviously raises other issues). However, if you're limited by diameter for how much power the prop can absorb, adding a blade will give better full throttle performance. At reduced cruise power settings, the efficiency gain of the 2-blade is more important. -Dana -- -- People in cars cause accidents.

Central Standard Time, tkrolfe@usadatanet.net writes: Ed, What's your hurry? I like to fly slow and gawk, that's why I built a FireFly ultralight. I normally cruise at 5,000 to 5,200 rpm which translates into 50 mph to 52 mph. Sometimes at 4,800 rpm if interested in a particular place and want to enjoy. I can go faster, but don't need to. Flying for pleasure, not to get somewhere. This is with an open cockpit, probably could do a little better with a full enclosure. Also, the number of takeoff's really increases the fuel burn rate. Fuel consumption goes up in mid summer with the loss of air density. Terry - FireFly #95 Terry, When you said you could go 120 miles before refueling, I assumed you were flying to get somewhere. So you figure if I held my RPMS to 5200 I should be able to go 100 miles on a tank? I havent tried going that slow when going cross country!
