Morning Denny/Gang:
That's as close as it will get thought. :-)
Just kidding, so don't get your feathers ruffled.
That goes for the rest of the Kolb Family as
well. Especially, if you are 2SI fans. hehehe
Seriously: Good luck with your project and be
safe.

I know how exciting it is to crank them for the
first time. Doesn't matter if it is a Cuyuna,
447, 582, 912, or a 912S. It is always
anticipation and excitement.

ED, I went out and took 4 pics for you of the rootrib and rear ring on my
firefly, I posted them on my website. I dont know if this will help you on
that Ultrastar you are re-building, but I hope so. It surely must be
similiar.
look on about page 7 or 8, misc pics.
Rootrib-2 vertical rows 1/8 rivets-1 inch vertical spacing and 1/4 inch
spacing from edges of chrome-moly ring.
Rear boom tube ring (at rudder).. 1 row of 3/16 rivets...4 per side...8
total spaced evenly around circumference.( there are actually 10 holes..with
the elevator pivot bolt occupying the center holes.

Ref. the 12/27/02 posting by Jim Gerken about Mikuni dual port pulse pump cracks:
I have one of each style that Jim talks about. I have a cracked cover exactly
as he describes, with 3 radial cracks coming out from the center hole (only visible
on the inside surface). However, my cracked one is the "cast boss" type
that Jim refers to as the "new style", and I have had that pump for 8 or 10
years. My other one was bought about 2 years ago, is the "old style", and does
not show any cracks.

I know exactly what you are going through. The weld shop that did my tank
made one of the bends the wrong way and then bent it back the other way.Most
welders brag about how good they are. 4 welders tried their hand at it,
finally the 5th one fumbled his way to build it. I pressure tested it at my
shop and circled 18 places that bubbled using soap. They touched up those
spots and also had it sloshed at a radiator shop. (probably not the best
stuff was used). . 7 yrs. later now I've had the tank out 3 times to repair
leaks. Coming out for the 4th and final time. As mentioned previously on the
list, I'll now go with the new poly tank.

I've looked at those cracks. In Jim's case it looks like "cold" flow lines
that were in the part at the time of Die casting. This happens as the mold
is filling and where the cold edges come together. There also may be some
flash left over from the prior injection. It is a only surface imperfection
and I'll bet could be polished out. I would do a dye check to see if it is a
surface imperfection or is a deep crack. You would have to wipe the dye
penetrant off very carefully so you didn't get a false indication.

I agree with you John. While Kirk is trying to be safety conscious, I feel
he's just a might paranoid from lack of exposure to the environment. I too
was a little concerned about fuel tanks but have learned that most UL
related accidents happen at low speed. I was more paranoid about 2-stroke
engines. Over time I developed confidence and trust of the 447 Rotax. If
there were some sort of substantiated problem with the Kolbs then it would
be different but the designs have survived the test of time with out any
signs of fuel tank safety issues. The one thing I have seen that scares me
more are those new builders who feel they must re-engineer what has been a
proven trust worthy design thereby compromising the design with their changes.

--> Kolb-List message posted by: "Alderson, James" <James_Alderson@jdedwards.com>
Does anyone have a spare or unused electric starter and hardware for a 503
that they could part with? I would really like one that allows the pull
start to stay on. Feel free to contact me off list. I am used to asking a
list before I buy anything, you would be amazed what some people have
sitting on shelves or in hangars. If not, I buy new....
PS - Is there a shrowd that you can buy to cover the selenoid for the
starter? It really isn't very nice sticking out like that.
Thanks,
James Alderson

Ed,
I can't wait to see your pictures, sounds like your are doing some very
creative work. If your fiberglass nose is heavy, you may try covering tubes
with fabric. It worked great for me. I used some thin aluminum flashing at
the top to get the curve I wanted, then covered over it.
Regarding your legs, I'd keep every inch you got. I built a step into
my tube/bungee gear & it worked fine. Could you clamp a step to the leg?
Long legs give you steeper angle of attack & allow quicker liftoff & better
3 point landings, most of all you could lower your engine & go to a 60"
prop. the difference in climbrate will be nite & day. Also long legs are
sexy.
Regarding flaperons, they were the best thing I did on my US, climbrate
increased, stall went even lower, descents could be almost vertical, rough
fields were much more managable, and in the reflexed up position, I got a
few mph more in cruise & would land in that configuration when the wind got
squirrelly as it would have less lift.
I have lots of opinions on UltraStars! Have fun, I'm sure your choices
will suit your flying the best.

> I just put the new aluminum FS 2 (1.25 inch) gear legs on and mounted
the 6 inch Azusa wheels and brakes. Problems include wheels that wobble
because of poor workmanship in manufacture that I was able to minimize by
matching different wheel halves and reassembling on an axle stub......and a
very difficult cockpit access caused by the longer gear legs. I now have 20
inches of prop clearance with the tail in the flying position. I can cut the
gear legs but need some input from the "experienced" US drivers as to what
would be acceptable in sod operations. I know my last machine with the stock
gear and 18 inch tires would cut grass at times.
> The Ken Brock seat tank is intalled and the nose fairing fabricated
from aluminum tubing.That fiberglass nose pod was rather heavy and I am
trying to save some weight .I am about to add a 5 gallon plastic tank above
the engine as I had on the previous US but this one will be removable and
will be used with a fuel vent system for drawing into the seat tank . It
will only be installed for trips. The forward fuselage section is now
streamlined wth the tail as with the Firefly and looks much better.
Centerline stick is in and all pulleys ready for cable...all the pushrods
are replaced by cable up to the aileron push tubes... I have decided not to
install the flaperon control due to the full length ailerons on this
model..... the last US flew slow enough and with the extra ailerons this one
should be slower.

Paul,
The 690L-70 is a 690cc, 70hp, inline three cylinder, liquid cooled two
stroke made by a company called Two Stroke International or 2SI.
It is very simple with no reeds, rotary valves, or oil injection, and the
exhaust is a very compact side mounted unit. It weighs the same as a 582
and has a flatter, wider power curve due to being a triple.
It sure makes a clean installation on a Kolb, now we'll see how reliable it
is.
Sincerely,
Denny Rowe
