Hey Big Lar::
Great pix of the MV Flyin; as luck would have it Delight & I were on a
wander. Met a few of the early birds at Gouldings
and stayed in Mexican Hat on the 18th. (Named for a natural sombrero
east of town) Drove up the corkscrew overlooking
the San Juan Goosenecks the next day. Your photos are now in my trip
album, thanks.

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

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,

along that plans-built line) for a future issue, too. (Sometimes finding

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. (Now, of course, I'm going
to have to start to balance how much coverage I give to Kolb aircraft as
compared to other models 'cause, believe me, some other group of builders of
another line of aircraft will wave the flag if I write about Kolb "too many

There is not and won't be a conspiracy to only write about expensive
airplanes from here on out (for the reasons I mentioned above) ... at least
not as long as I have a reasonable amount of influence on the magazine's
content. Will there still be stories about those "expensive" LSAs? Yes,
there will ... but I'm telling you that it'll be balanced by stories about
affordable airplanes. You can hold my feet to the fire on that promise.

Subject: | thrust angle of SS |
--> Kolb-List message posted by: "Rusty" <13brv3c@bellsouth.net>
Working on Waynes Sling shot we found we could change the engine angle by
installing the rubber motor mounts inverted on one end and shim with washers
to get near the 3/4 rise that was recomended.
----------------------
What a neat idea Woody. 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.
Cheers,
Rusty

Maybe it depends on how you change the RPM's in order to affect the fuel
burn rate.
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.

5800 RPM for cruise seems high - you may need to add more pitch to the prop
- see below. 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. (Were soft here in Texas - used to 100 degrees in the shade
during the summer.)

The first time I read your post I didn't catch you weren't running with at
least with a wind screen, you may want to install one. 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.

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. 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.

Hi all,
everyone`s pics of the MV fly in made me green with envy. 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.

Firefliers,
I would be indebted to any firefly owners that know how much weight is on
their tailwheel , or would be willing to weigh at the tailwheel. I have a
per plans Firefly # 062, and weigh about 170 lbs and I have not done a weight
and balance. I figure if there are Fireflies flying out there that have a
greater tail wheel weight than mine I should be OK!

Richard,
First were discussing a only the Rotax 447, not a different model
engine. 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.

Take the wings off and move/store them separately. Unless the Xtra is very
different from the MKIII, you are only dealing with one more bolt per wing.
Simpler than dealing with dollys, trollys, heavy lifting, etc.

Pat,
Doesn't it just....
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...

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?

Ed,
From my flight log:
April 14, 2004 - Flight 410 - 31 minutes - 127:06t, Victor 1+ - 48:06 burned 01.15
gallons of fuel for and average of 2.23 gph. Weighed the FireFly before flying.
Right wheel - 111.5#
Left wheel - 108.0#
Tail wheel - 56.0#
Total weight- 275.5#
Gas weight - 18.6
Coolant weight 2.5
Tot. wet wt. - 21.1
FireFly dry weight = 254.4 pounds - Removal of the extra instruments and power
converters from the seat cushion will bring it back to less than 254 pounds.
I weighed my self ready for flight with radio, gps, recording system, and flight
helmet, and I weighed 202.5 pounds. Initial total flight weight was 478 pounds

--> Kolb-List message posted by: "George T. Alexander, Jr." <gtalexander@att.net>
Kolb Listers:
From Rick Neilsen's earlier message, I have received some pictures from the
Monument Valley trip. 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.
Thanks,
George Alexander

It appears there is a usage bandwidth limit.... I've gotten feedback from several

Jerb, I called Homestead support and found out that I have exceeded their BW limit
and noone is able to access the site now. I've emailed them to see what my
options are. If upgrading will give me more BW for viewers, I'll do that.
They never mention any BW limits in the sales info of course.... I guess this

150 picture limit as long as noone tries to look at them!
Hopefully I'll have this squared away soon and will post an update when I do.

I think we also shimmed the metal flanges on one side of the mount to have
the mount sit at an angle in the frame also. I think it required 3 washers
each hole to keep the through bolt straight and minimize the stress on the
mount.
