Just FYI ... from Sun 'n Fun I went to Germany to the Aero 2005 show for a week and then came home and got bronchitis ... so I'm definitely behind on responding to e-mails ...

Anyway, so much for my sad but true life story. > > I fully understand how you and others may feel that we've abandoned low-priced airplanes. The problem I've been trying to balance is to provide as much information as possible about the new rule ... we felt EAA had responsibility to do as much educating as possible about it ... with a variety of coverage of a variety of machines ... fixed-wings, trikes, ppcs ... and planes of various cost ranges. And, at the same time, we like to be as on top of the news as other aviation magazines, otherwise they "eat our shorts" (if you will) in that regard. And, frankly, some of those expensive planes are what's been making the news. > > So, now, what does that mean for the future. Well, starting with the June issue, you'll start seeing more features about more affordable airplanes.(M-Squared in June; Hawk Ultra ultralight in July)...some of the space we could have given to that earlier went to educating about the rule. You'll start to see more articles about people who built and fly their own machines ... a Sonex in July ... a RANS S-7 later this fall, for example, and I'm actively seeking an article about a Piet builder/owner (or something along that plans-built line) for a future issue, too.

Believe me, he's still on my list and unless he rejects the idea of us doing a story about him, one will be done. I just have to figure out when I have time to write it. That's the honest to gosh truth, but my "plan/hope" is to get written and in the magazine before this calendar year is out.

Thanks! I just took a look at the mounts, and it looks like you get almost an inch difference in height when you turn one over, but keep the flange on the top side of the steel mounting frame. I can't see why this would hurt the mount, but I would certainly make sure there was a large washer (2") on the bottom to keep the assembly captive in case the mount failed internally. I measured the angles of the wing and mount in it's normal 3pt stance yesterday. The wing bottom is at 10 degrees, and the mount is at 13 degrees. If Jack's measurement for the Firefly translates to the Slingshot, then the wing flies at an angle of attack of 7 degrees. Raising the tail to flying angle would mean reducing the angle of the wing and engine mount 3 degrees. That leaves the engine still 10 degrees positive angle in level flight. I figured it would take a 1.75" spacer to remove the 10 degrees of angle from the engine mount, but that seems like double what most have tried. Perhaps it would be wiser to start with the 1" that I get from inverting the rear mounts. The two problems I see are overall height of the engine to clear my garage door, and clearance for my 72" prop from the tail boom tube. I don't think either will be a big deal though. Within a couple weeks, I should have a dummy engine block in place on the plane, and can get a better idea of what I need for clearances.

I have found that dialing in a lot of pitch in order to run the 582 slower than normal does not affect fuel burn very much, in other words, if I am propped to turn 6500 at WOT level flight, or propped to turn 6300 WOT throttle level flight, fuel burn does not seem to change much (that I can tell) , because it still takes a certain amount of hp to maintain cruise speed. You can obtain that hp by turning the engine a bit faster at a lower throttle setting (less prop pitch), or turning it a bit slower at a higher throttle setting - (more prop pitch) but either way, it still needs X amount of horsepower to fly at a given airspeed, and the only way you get that power is by burning X amount of gasoline. To the extent you can get the airplane to be more efficient at making lift and slicing through the air, then it takes less horsepower to maintain a given speed, - usually manifested as a lower RPM at a given prop setting, and fuel consumption goes down. Once you have obtained this, then prop for a good compromise between climb and cruise and forget about fooling with the prop. My 68" 2 blade IVO is set for a climbout of around 6,300 RPM at 50 mph WOT, and normal cruise solo is about 52 - 5,300 rpm at 65 mph, which burns about 3.2 GPH. The best example of this was when I flew the 532 powered MKIII to Oshkosh along with two 503 powered Drifters. They were running 5,500 RPM to get a 55 mph cruise, and I was running 4,900 RPM to get 55 MPH. The Drifter is aerodynamically really dirty, even compared to a fat bodied MKIII, so their fuel burn was always higher than mine.

We found the adjustment below produces about the best over all performance, climb and cruise. With the enclosure we would run 5200-5400 RPM with 60+-70 MPH cruise. I forgot what difference we observed after adding, but it did improve the cruise speed. With the tail tied down adjust your prop to produce a full throttle RPM of around 5900 RPM - this should give you around 5900-6100 RPM on takeoff climb out. I have a EIS with the fuel flow transducer option on my Hawk which also has a Rotax 447. I found that prop adjustment can significantly influence fuel consumption rate. We had to do some just change on the carb but found we had to watch the EGT's in the throttle mid range ~4000 RPM. Some one posted a change of the needle jet that was suppose to cure that but we never tried it. We didn't run our FireFly long with just wind screen, quickly added the full enclosure as the air blast in the FireFly isn't like ridding a motor cycle unless you slow it down. I understand Jack Harts comment regarding strain on his neck. We installed only the front portion of the enclosure kit, never installed the rear clear vinyl portion.and found that cured the wind issue and provided adequate protection for comfortable flights down to 45-50 degrees.

It not that hard. Use the blue low stick masking tape sold in the paint department at Lowe's or Home Depot. Clamp the side of the Lexan down - mark your cut lines with the tape, top, bottom, & sides. Use the tape to make the needed cut lines, makes it easy. You can cut the Lexan with tin snips. I think you'll see some difference just from that alone. Over coming drag requires more power, this equates to more RPM and higher fuel consumption. Still think you need to adjust your prop's pitch. AFTER ADJUSTING THE PROP ALWAYS DO A STATIC TEST WITH TAIL TIED DOWN BEFORE FLYING - watch the EGT's - stop if they are too high >1050 degrees, indicates you may not be loading the engine enough causing the EGT temps to rise. jerb At 05:21 PM 5/26/05 -0700, you wrote: >--> Kolb-List message posted by: "nmatthew" > >The total weight of me, fuel and gear is 562#.

I tried experimenting with the 582, cranking in pitch until full throttle RPM static was below 6000, but it suddenly became unreliable. Too much load, dual carbs, it would just plain lug down, moan like a mournful Wookie, and intermittently refuse to get above 5400 RPM. Decided 6000 was minimum static for a 582, currently using about 6250, gives a healthy 6350 - 6375 rpm climbout. Something else to consider - lugging any engine is hard on needle/roller bearings - My buddy that has the 582 FSII bought a Drifter from a skinny guy who built is as a single seater, and because it was light weight, propped it for about WOT 5700 RPM static, happily flew it that way for a couple hundred hours. Big Ed bought it, repitched the prop normal, but the crank seized a rod big end at 375 hours. Cause and effect? Who knows? Just my .02$ worth.

Great shots. The extra is coming along, start painting tomorrow with luck. However there are a couple of problems. My Challenger occupies my hangar and I may have to keep the Xtra, wings folded, in one of the barns at the farm strip I fly from for a time. With the wings folded the leading edge tracks perilously close to the ground and will certainly hit when moving the machine about the fairly rough farm yard. The other problem is that the tail end with wings folded is HEAVY. Has anyone devised a lifter/cum trolley that would enable the tail to be lifted so that it could be wheeled about with the leading edges well clear of the ground? In this country we cannot change things by fitting bigger tail wheels and adjusting wheel struts as you do.

On the Rotex 447 we have found that the magic number seems to be to prop for around 5800-5900 RPM full throttle in a static condition, that is tail tied down. If you under prop, your EGT's will be too high, if over propped you can't turn up RPM to get the HP. The comprise comes in pitching for the best performance for cruise and climb. Were not lugging the engine in this case. jerb At 12:55 PM 5/27/05 -0400, you wrote: >--> Kolb-List message posted by: Richard Pike > >That's probably ok with a single carburetor, be careful trying it with duals. >I tried experimenting with the 582, cranking in pitch until full throttle >RPM static was below 6000, but it suddenly became unreliable.

I fly from a farm strip in the UK and have the same problem.. We have made a trailer that we run the MKiii onto then fold the wings... we can then tow the whole thing around the farm and into the barn... Can take photos if you wish... Mind you 40 by 40 hangar is on its way shortly...

Great shots. The extra is coming along, start painting tomorrow with luck. However there are a couple of problems. My Challenger occupies my hangar and I may have to keep the Xtra, wings folded, in one of the barns at the farm strip I fly from for a time. With the wings folded the leading edge tracks perilously close to the ground and will certainly hit when moving the machine about the fairly rough farm yard. The other problem is that the tail end with wings folded is HEAVY. Has anyone devised a lifter/cum trolley that would enable the tail to be lifted so that it could be wheeled about with the leading edges well clear of the ground? In this country we cannot change things by fitting bigger tail wheels and adjusting wheel struts as you do. Help please Pat do not archive -- How much free photo storage do you get?

Any suggestions on adjusting it? > >Matthew North >Tucson, AZ Matt, In comparison to the stock FireFly, you are flying an overloaded wing. The gross weight recommended for the FireFly is 500 pounds. To carry the extra 62 pounds means the wing has to work harder. The wing can do this only by flying/cruising at a higher angle of attack. This translates into increased drag which eats up additional horsepower and fuel. To get better fuel burn, you can loose weight and/or chop weight off the Firefly, or you can add more wing. All of these options are difficult. You have to make a de lima. What are your stall speeds? Jack B.

Rick and Wil Uribe have sent some of theirs and I have posted them to the following url: http://home.comcast.net/~kolbflyer/ If there are others who have images that they would like to share, you can send them to me via email and I will post them to the site. A couple of requests...... Pick no more than 10-15 of your better ones. Based on numbers that we get, if there is additional space, I'll put out another call for more images. and Because of the limitations on my email box, either cut back the file size to something under 100K per image or send only a couple in a message and then send multiple messages. Depending upon how much mail comes in, you may have to do both. If anyone has text/narrative that they would like to include, send that along in a text file or word processing file or email message, and I'll post that with that person's images.
