Hi Lucien,

It doesn`t matter if you watch the ASI or an AOA indicator if you listen to 
the glider and feel that slight judder, get the stick forward sharpish and 
you should head off a stall everytime.  I was taught NOT so much `stall 
recovery` but RECOGNITION of a stall before it happens. Gliders pilots who 
are thermalling in a gaggle of say 20 other gliders all banked at 30 degrees 
or more 5 knots above the stall all in an area a few hundred yards across 
will have his ears on the audio for the vario and his  eyes outside,  not 
watching instruments. Glider pilots will just ease the back pressure 
slightly when that `judder` occurs as they can`t afford to lose the height 
which a power pilot can easily recover.

If you want to see some incredible glider flying see Youtube under `Nutter 
at Kemble` (I think) there is film of a display at at Kemble Air Day  with 
the glider pilot doing rolls while still on aerotow. Also mirror flying with 
the tug.Fantastic.

Cheers

That's the way I learned it - referencing airspeed with an ASI for stall recognition/recovery
is not a theory of fixed-wing flight that I'm familiar with or
ever heard of being taught. Maintenance of angle of attack is the only method
of stall avoidance and recovery that I've ever seen work in any airplane I've
flown and it's what my instructors have always taught me as well. 

Fortunately, in light aircraft like the Kolb, this isn't a difficult skill to acquire.
In my old FSII, I never needed to use the ASI for anything other than
making sure of V-speeds like Vne; in my titan I also rarely look at it again once
I'm on downwind and configured for the approach. I'd say I stopped needing
to use it at about 40 hours in the plane, about the same with Kolb.

Same thing in the glider I'm learning in right now, the ASI is used strictly for
airspeed and never for stall recognition or recovery.

Being a glider Pilot I was not familiar with stall warning horns as I learned how
to recognize a stall directly early on in my training.

As a matter of fact I can't imagine how a pilot could not recognize a stall.

There's plenty of other signs if you are paying attention.

Maybe its different in a Kolb since I have not flown my UltraStar yet.

I guess the point of this thread is that the pilot is filming and will not be paying
attention to flying the aircraft as much and needs audio assistance as his
eyes engaged elsewhere.

Perhaps a copilot is an even better idea, although he could surely benefit from
VG's.

Some aircraft (mainly faster aircraft) have more abrupt stalls, but should 
be no problem in your US.  'Bout the only issue you may have is that the 
best climb is practically at stall speed, so there's a narrow margin... but 
the US hardly stalls at all, you feel the buffet and it mushes a bit, but 
you gotta try hard to get a real "break" with the nose dropping.

Pat and Kolbers,

I flew gliders for several years, and what has been said here is true.  But, 
it is easier in gliders, in that, one does not have the distraction of 
engine noise and vibration.  They tend to mask what the plane is really 
doing.  In a glider, your lower cheeks will tell you pretty much what the 
plane is doing and the sound of the wind flowing around the canopy tell you 
your air speed.  In powered flight, you still have your lower cheeks and if 
your controls are light, feedback from the stick, but sound is pretty well 
masked by headsets and/or noise protection and high background noise.

Cloyd,

  First of all, hello!  I haven't heard of you before.  (Maybe I wasn't paying
close enough attention.)  I'm glad to hear you either have or want to have an
Xtra, the finest lightplane around, IMHO.  

  Now, to answer you question, Cloyd.  An Xtra is a long SOB.  I have one wing
folded on my plane, so it was easy to take a reading....just hook a tape and walk
toward the front.  I come up with REAL close to 24' 4", or in there somewhere.
In my particular case, I'll be adding about an additional 6" per wing, when
I finally get my droop tips attached.  So, you are looking at the minimum
of about 25' interior length.  Recommend 26'.

  Plus, it seems like someone was asking how tall a trailer should be, to roll
an Xtra inside of it.  IIRC, I came up with just under 6 1/2 feet tall.  I'd need
7',  now that I installed the steel gear legs, which raised the fuselage by
at least 5", possibly 6".

  For your information, and any others that don't already know, NO, I don't have
an Xtra.  I have a MkIII Classic I converted to look like an Xtra.  Is it the
same dimensions as an Xtra?  YES!!!  Does it look like a genuine Xtra?  YES!!!
 I got my dimensions from a genuine Xtra frame (Ala Pat Ladd's Xtra in Great
Britain).  After making all the fuselage cuts and welds, I installed a genuine
Kolb nosecone.  The differences between my plane and a genuine Xtra are so
subtle that 95% of most Kolb owners wouldn't know it wasn't, if I didn't say
anything.  (Once I get it finished, I'll be raising that 95 to about 99%)

How about a few photos, if you have an Xtra already??  I enclosed a photo I took
awhile back of my MkIII.

Best to ya,

If the strip is private, and the deer are 'damaging crops' or

It will depend on your state wildlife regulations.  I know that in CT you 
can get a "Deer depredation permit" which allows you to shoot deer that are 
damaging crops, dunno if they'd allow it for an airport... can't see why 
not if they're endangering human life.  Depending on the surround area, 
though, there might be restrictions, like no firearms (bowhunting only) or 
other restrictions.

Of course if it's your own land and nobody else is around...

No, it would not.

Now, I'm less sure.  Yesterday before trailering the plane home, I pulled 
it out to look at things.  I noticed fuel dribbling from the carburetor 
vent tubes, something I've never noticed before.  And the trailer floor 
under the carb was damp with fuel/oil.  This is a pretty clear indication 
of a leaky float needle, which would cause _rich_ running, not fuel 
starvation.  Still, an excessively rich mixture can also cause engine 
stoppage... or a worn needle could also stick closed.  Or crud, but either 
way it's pointing to a carburetor issue... probably won't pull it apart 
until the repair parts arrive in a few days, though.

Yes, it sure was nice to have!  It makes for a better pull angle on the 
ground, too.  It's just a piece of stainless sheet bent into a "U" shape 
holding a pulley, on the LH universal joint bolt.

Rick,

Build yourself a radio activated propane cannon.  5 clicks on 122.85 
fires the cannon, scares the deer and all the neighbors.  The cannons 
should be available through farm suppliers.  The radio part would have 
to come from an airport lighting supplier or someone handy with circuit 
boards and a soldering iron.

Subject: Kolb-List: Cuyuna Cooling

REF:

In the mean time I brought out the Cuyuna 430 and am
prepping it to go in the UL-202's place for now.

They are Identical to the UL-202 except for the 7lbs
extra weight and a single 28mm carb.

If it works out I may go to dual carbs for more power.

I hear some were getting near 40 hp from a dual carb
430.

I'll compare it with the other engines performance to see how it 
compares.

Ray,
    
    The 430 is not identical to the U-L202.  The early 430's went to the 
32 MM carb,  double head gaskets, and a special flow thru head, to try 
and cool them.  With only partial success.  The flow thru head had every 
other fin removed, to try and get more cooling air to the original head 
on the rear cyl.  I think most of this was incorporated into the UL-202. 
 I also believe the 202 had different porting locations on the jugs, in 
an effort to get more torque into the mid range.  

    The only really successful Cuyuna I ever saw was on Richard 
Swiderski's Ultrastar "Stork", and he ran dual carbs. I think he also 
used parts from both the 430 and the 202 on his most successful version. 
 He may still be on this list, maybe he'd share some of his experience.

    You probably do have a too much prop. Only good fix is a ground 
adjustable.  Leaving it a little bit over propped will usually help keep 
EGT's in check. In my experience, the ground adjustables will out pull a 
fixed pitch even running at the same rpm.  True anyway for Warp, GSC, 
and Powerfin. Probably not true for the old flat-bladed Ultra Prop.

Dana & List,

I apologize for tossing out some numbers with out explanation.  I used a 
quick graphical solution to come up with relative numbers for an aileron 
one-half the chord.

It rained today so I worked up a similar graphical approach to match the 
modifications I have made to the FireFly.  The results can be seen at:

http://www.thirdshift.com/jack/firefly/firefly139.html

I inserted some responses below.

If your maximum aileron down deflection is 20 degrees, there is more than 
enough stick deflection.

In my case, I was able to reduce "Tee" hole spacing to gain greater 
mechanical advantage and therefore reduce stick force required.

All that extra effort that you have to exert to deflect the aileron has to 
go some where.  Some of it goes into twisting the aileron torque tube.  The 
rest and probably most of it goes into twisting the wing ribs about the main 
spar.

In the FireFly, there is one pin through the main spar attachment point to 
the cage. Also a second through the rear wing universal attachment point.  
And two more through the wing struts.  The only thing that keeps the wing 
from kicking up in the back with down aileron is the most inboard steel rib. 
 This leaves the outboard portion of the wing to progressively twist up 
under this condition.  Since the airfoil lift profile usually centers over 
the main spar this twist is not usually harmful. 

I hope this helps to explain why reasonably small ailerons may be of 
benefit.  Would I change back?  No way!

From: "jb92563" <jb92563@yahoo.com>


Thats puzzling as it took prime to restart in the air.

I wonder if the floats could be binding causing the possibility of lean or rich.

I found acetone dissolves the gunk very quickly.

I have my Cuyuna 430 mounted tonight on the US and am soaking the carb in acetone
to get rid of all the old gunk.

I'll let it soak overnight and tomorrow evening brush and flush it out and mount
it on the engine.

Should be able to try out the engine this weekend.

Thats good info...and since I have one of each perhaps I can make that perfect
engine between the two.

For now I'll try the stock 430 with the 28mm carb and it does have the modified
cooling fins.

I can rebuild the other one in the mean time.
