FireFlyers,
The orginal request was made about performance of a Part 103-7 FireFly. And
my answer was given in that context. I don't know how many on the List have
flown a legal ultra light vehicle FireFly or currently own one, but I have
noticed quite a few currently sport N numbers.
Anyone can take an experimental and boost the empty weigh by adding more
engine or whatever, but it takes some effort to stay within the Part 103-7
bounds. If you have or have built a FireFly with less than 15 inch chord
ailerons and it is close to 254 pounds empty with a Rotax 447 mounted, it is
overpowered. All the comparisons you want to make to Kolbras and other
forms of Kolb heavy metal will not alter that fact. Check out AC 103-7
Appendix 1, 2, 3 & 4.
It is good that by the end of the year there will be no fat ultra light
vehicles as they will change into undocumented experimentals and illegals.
It was good to hear from Pat that they are offering the FireFly in UK with a
27 hp engine. It seems to fly very well.
The List seems to be dominated by the thought that more power is better.
But with the addition of power comes increased weight, wing loading and
stall speeds, increased dynamic loading of the air frame, which means things
start cracking. These must be bulked up and so more weight is added. If
you want to do this, it is your right, but cut us guys who want to remain
Part 103-7 legal a little slack.

Subject: | Re: How do you like your FireFly? |
Used to have a FireFly for a number of years. I assure you it is not
under powered with a 447. It's like a little sports car version of
the Kolbs, small and quick. It flies very well, gets off great. My
partner and I were not exactly light weights, both in the 250# plus
area. It is not for a real tall person, my partner was 5-10". If
your much over that you head can start hitting the wing root
cover. Fun little airplane that doesn't take up a lot of hangar
space. Were were fat and built it knowing we would be. We had the
larger dia, wheel barrow wheels, (didn't like the 5", worked the gear
pretty hard on rough turf). Also had brakes and a very well equipped
instrument panel plus the full enclosure, VLS chute. We had the
expansion go-kart type brakes, if doing over I would adapt it over to
band brakes, they work better and weigh a lot less. Had flown it
with the short wind screen and the full enclosure, much nicer flying
with that. The wind flying it seems to be much worst than I remember
a motor cycle being. I do feel it is a little more challenging
airplane to fly, liked that but probably not the best plane for a
person just learning to flying or those with minimal flight
time. Heard that the new owner changed to different tires/wheels and
it improved its ground handling. (It had the thin Chinns tires on it
as came on the wheels from Kolb.) Since both of us were old tail
wheel pilots, we didn't have any problems with it. Do a search on
guy morgan on the list regarding his changing the tires/wheels. It
was fun to fly, but could only carry 5 gallons of fuel as
configured. We found we could stuff a couple 2-1/2 gal. jerry cans
in around the existing tank. Before we sold it we were looking into
ways of increasing fuel capacity to give range to make it to and from
other area airports especially with any major head wind. We flew it
in fairly windy conditions but again we were experienced pilots and
had hundreds of hours of tail wheel time under our belt.

The legal status of a "fat ultralight" does not change at all. They are no
more illegal on Feb 1st than they are now. People that are making money on
the SP transitions like to imply otherwise. I guess we will see.

Jack and guys and girls,
Very well stated, Jack. I think you deserve quite a bit of credit for trying
to maintain a legal Part 103 ultralight. It is no easy task, I'm sure, balancing
necessary performance and safety requirements within such stringent perameters.
Although this isn't the direction I'm headed with my current Kolb, as I stated
a few days back, there may be a Firefly in my future...someday. It is comforting
to know that a particular aircraft is available, with excellent performance
and handling, and still remain inside the guidelines of the regulations.
It doesn't take years and years to build a Firefly, does it? Just curious............

I finished the Poly Fiber fabric on the MkIII fuselage and got one coat of Poly

edges, and misc. reinforcements. I did a fantastic job on the Poly Fiber, if
I do say so myself. That, or it's just easy, whichever. Anyway, the fuselage
looks just plain awesome....

Subject: | Re: How do you like your FireFly? |
I think the Firefly would be a really fun plane to own, although I would not even
consider making it 103 legal. Building it as an experimental and putting
an N number on it is not hard at all. One could end up with a much better and
durable plane by adding a couple more pounds.
As far as engine, I would put a 503 on it, much more reliable an better than the
447. As far as some that say its overpowered, those are guys that have small
engines and try to convince themselves that they made the correct choice by
having a small, sub standard engine... Nothing says you need to fly around at
high power all the time, but lots of power is a really great thing to have when
you need it. More power is also safer, will get you out of trouble when you
need it, you will get off the ground quicker, and on takeoff you will also
be a lot higher at the end of runway.. If the engine quits on takeoff, you will
have several hundred feet more altitude then they poor guy with the small,
very light engine.
I have flown with a lot of Learjet pilots over the years, and every one of them
loved the 45 degree climb-outs, and quick takeoffs. I have NEVER heard anyone
say that any plane they actually flew had to much power. The only people I
ever hear talk about some planes "having to much power" are pilots of doggy,
sluggish airplanes that are trying to convince themselves that a lack of power
is a good thing.

Tailwheel on electronic scale=56# When I came home, the dang scale
had 'slud' over and fell on driveway when I opened the door! Now my

I as J D have listened to the comments Kolb vs Challenger and had to say so
mething.
I have a Mark 3 w/912 and a modified Challenger 11 CW special w/503 and bot
h have their
good and not so called good points, it all depends on what you want or need
.
My Challenger will perform and stay with the Mark 3 except for roll off dis

Subject: | Re: How do you like your FireFly? |
Mike,
Do you have any stick time in a FireFly, I have and there is plenty
of power there with a 447.
Our 447 worked fine and mine on my Hawk so far has performed
well. While I will agree the 503 is a good engine, (especially like
oil injection no premix - less stale fuel to deal with) it would just
add more weight to the airframe. Got to remember the FireFly is a
light airplane compared to a FireStar and you need to consider the
specified gross weight limit of the airframe.
As for building it to meet the 254# limit, I'm confident it can be
done - no extras. I know what ours weighed and what contributed to
the weight. Go with 5" inch wheels, band brakes if any, wood prop,
bare bone instruments (non-sensitive altimeter) - air speed, and toss
up between analog EGT/CHT gauges or Grand Rapids Technologies EIS,
and if you must, the open wind screen rather than the full
enclosure. (I would still take the EIS, it's a wonderful piece of
equipment.) As for climb out at our weight (both plane and our full
figures) we still normally pushed in excess of 1000 F/S on climb
out. We had an electric Variometer like used in gliders - was very
sensitive and accurate.
