Just buy a set of plans, get an Aircraft Spruce catalog, make up a bill of material
and add it up.

| Subject: | Help with FS Wing Gap Seal |
I purchased a FS KXP which has a permanently mounted lexon gap seal that bolts
into place. The builder never unfolded the plane, but I will be. I purchased
some clear vinyl & Velcro to make a new gap seal. Presently the leading edge
of the wings rest on & nearly touch the hoop that is above the pilots head when
the pins are in place. Here are my questions:
1) How far back under the wing is the gap seal suppose to go?
2) With the leading edge of wing almost touching the hoop, does the gap seal go
under the hoop or is it somehow held in place on top of the hoop & then the wings
folded on top of the gap seal? Either way, I am six feet tall & with a helmet,
I would be nearly touching it or maybe even slightly above the hoop height.
Anyone have this problem?
3) Complicating things, the full length windshield rests on the top front edge
of the hoop for support against the wind pressure. It is only secured to the
nose cone. This setup may be incompatible with folding the folding wing process.
My hoop doesnt have any of the tabs that allow the windshield side supports
which run to the nosecone like many of the Firestars have.
I eventually want to go to a full enclosure for the front. But for now, I would
like to just come up with a gap seal that will allow me to fly for awhile.
Any suggestions would be appreciated. Richard Swiderski

Hey John,
Aren't you close to Wetumpka? Hoping y'all are all ok after the tornado.

My thoughts, having owned and rebuilt an Ultra Star; Never flown...but am t
old that it is the best flyer of the whole Kolb stable..neutral thrust for
one..Per Hauck...
for starters.very minimal fuselage..the Firestar gear is a definite good
mod...the low to the ground prop is always in danger of nicks...the Cuyana
engine was good for the time..but I am told that it tended to leak between
the thin case halves..Electronic ign on the UL 202 , made for easy starts e
ven being inverted. If I had another one, I might try large bicycle wheels
to improve prop clearance. The fuel tanks worked but could be improved on
today..
All in all...not a good plane to build these days...Likely many sitting h
ere and there not flown for years...I would place a want ad on Barnstormers
. $1000 dollars or more plus shipping for two wing spars makes me shiver..
.then again...so does the price of hamburger! :-)
I gave 1k for mine as a project...the cuyana engine is not worth much...v
ery old...35 to 40 years old I think? The 377 or 447 should work. They are
old too!! Hirth seems to have mended their reputation...so should be consid
ered given that KOlb is using them..
I bought the Firestar II for 6k...with high time 503...and I do not dou
bt that you would spend as much building a US...
Two Fireflys sold on Barnstormers some time ago for 6 or 7k as I recall.
.for both..from the same seller...I could not get a picture before someone
, more local beat me to them..Minnesota? but I would have paid shipping...
and still have come out...A good Firefly with low time engine is worth 9 to
10 k in my book.
I have a boom tube, tail feathers and wings for a Firestar... I want to t
urn them into some sort of hybrid not unlike the US...but with a wooden fus
elage..
Here is what can be done with a bit of imagination...Bill Bronson's Kolb
parts used in a half vw tractor config...Herb

Thanks for the great comments Herb. I pretty much suspect that you can buy most
of these planes used for less than the cost of the materials, or at least that's
how it works when I sell something.
For years, I've wanted to build a steel tube fuselage for some odd reason, and
I like the Kolb construction. Unfortunately, the US is the only model they offer
full plans for. I may very well buy the plans, since they are available,
but I might save it for a future project.
As for combo planes, I also have a set of Airbike plans, and thought about maybe
combining the Airbike fuselage with Kolb wings (because I don't care for wood
construction). Somehow it seems a little too life threatening to eyeball something
like that.
I'll keep looking around, and see what I can come up with for Kolb projects.
Cheers,
Rusty

Richard: I had an Original FS with an aluminum/polycarbonate gap seal that went
a little over a foot back on the bottom side. I am 6' 2+" with a fairly long
torso. A friend had a similar situation (not as tall but a longer torso) in
his Original FS. I think Dennis Souder came up with a solution (which I copied).
Cut a hole in the underside of the gap seal big enough to receive an inverted
10" aluminum pie pan. That was deep enough to give you an additional 1"
plus head room. The angled sides of the pie pan didn't offer any significant
restriction for head movement.
The best picture I could find is attached. Not very clear but you can see that
the top of my helmet is above the bottom surface of the wing.
Good luck!

just sold an airbike and for an instant, I considered using the Firestar wings...7
rib...
I never want to build another set of wood wings....!!
The best flying plane I have had is the N3 Pup...The landing gear is a bit too
lite for my long strip...and I landed too fast...went long and hit a rise
that collapsed the left gear leg... Sits in storage waiting for the mood to strike..
I liked the Fireflys a lot...and would trade the FS II for one...Reg. EAB....waiting
for the Gov shut down to end to get the paper work back from Oak city..
