Subject: | Flying videos thermals! |
I guess I am hard headed but I always wind up going out to fly in mid day conditions.
I hate getting up early and I hate going out late and getting home late
especially with the time change having it get dark around 8 so I choose to fly
in mid day conditions.
I don't know how rough it is in larger planes but it sure gives me a workout keeping
the wings level and the airspeed and altitude constant. The winds were not
bad at 5 to 10mph but thermals were!
Its fun though and I can climb over it. It has helped me flying in these conditions
to become more comfortable with the airplane. The rough air still makes
me a little nervous at times especially low on final when I get a good toss.
I have posted 21 videos! WOW I didnt realize I was enjoying this camera so much.:D

That kind of air brings up my only complaint regarding my Kolb.
Strong up/down drafts involve
what I consider to be excessive pitch changes and corrections.
Whether it is a symptom
of only my individual airplane is open to question. I would prefer
that the result of a
sudden boost from below would involve less noticeable speed and pitch
changes.
Wing leveling corrections are understandable and are common to all
craft but
watching the ASI go from 40 to 80 in a matter of seconds is not
comfortable.

Hi,
I used Marvel in the fuel of British sports cars in the '70's.
Seemed to prevent sticking valves, didn't seem to hurt. I use their Air
Tool oil as an after-run oil on RC 2-strokes, works great.

Reading on the net...appears that MMO has phosphorous as its active
ingredient... Dump a few ozs in the tank and carbon and sticky rings are
a thing of the past...I also toss one oz over my left shoulder... :-)

WHAT IS IT?
My own understanding from earlier articles on the subject is that
Marvel Mystery Oil is a light viscosity oil, roughly equivalent to an
SAE 3W, containing (among other things) about 20 percent solvent
(probably mineral spirits), dye, wintergreen for smell, and 790 PPM of a
phosphorous additive.

Hey Bob!
Might be that unconventional power plant. ;-)
Seriously, and I'll try my best to be, that is not a common problem with
Kolb aircraft, of any model, that I am aware of.
I don't like rough air either, but in most cases, if you are going to get
where you are going, ya gotta fly...
John W and I had a unwritten law of anything over 25 mph ground speed was
reason for staying on the ground. We demonstrated that May 2008, when we
spent three days waiting for the wind to subside at Ontario, OR. The wind
averaged about 45 mph for all three days and nights. Got used to walking
around at odd angles.

I am guilty of flying too low also. 25 mph wind over the flatlands
is fine.
When the terrain is bumpy it's time to climb.
The lumpiest part of most of my rides is when I descend to the
rolling hillsides
returning to my home strip.

My FSII did that as well in thermally conditions, but then again the Kolb isn't
an Edge 540 as far as control authority goes.
The last time I flew my FSII in midday thermals was one hot day back in TX and
that was indeed the last time I ever did that.
The titan has significantly higher limits in stuff like that, but even then I prefer
not to battle airmasses that are trying to slam the plane into the ground
while I'm trying to land.
The trip back here to NM from nebraska, I ran into the midday stuff over Kansas,
as that was about 1 or 2 in the afternoon when I was out in that particular
area. I had it slowed down to 90 and even 85mph, and I was still getting popped
up into the shoulder straps from time to time.
I've just accepted over the years that I don't like flying on the edge of control.
Regular full-stop control movements just to maintain flight or keep the plane
out of the dirt isn't a region I like to be in. I'm ok being a wuss nowadays.
but in good smooth air, there wasn't a much more fun plane to climb into than my
FSII. Even after I'd bought the titan and before I had to sell er, I was usually
in the FSII in late afternoons shooting wheel landings or sightseeing rather
than the other plane.
I can tell I'm pining away for that plane a bit. The firefly idea keeps coming
back too...

I hate being throw up in the shoulder harness! I hate roller coasters and thats
what it feels like when the negative Gs occur! :(
My asi didn't fluctuate much over 10mph and the fluctuations were mostly positive
gaining asi. Strong up/down drafts do not seem to be that big of an issue
in my plane. There are times when I have to be aggressive with fore or aft stick
to overcome a vertical gust but for the most part I only make minor pitch changes
to maintain a stable pitch attitude.
I did have a lot of horizontal gust which was causing my plane to yaw around a
bit. You can see it happen alot in the videos. Just the ole girl wagging her tail.
[Wink]
I guess thats just a matter of where you are in relationship to the up or down
draft as to how it affects the airplane's axes

Subject: | Air Force base open to civilains for two days in May |
FYI
The Ellsworth Air Force base at Rapid City SD is allowing civilians to fly in on
May 23 &24 of the Memorial Day weekend. All you need is a radio.
Arrival is morning. There will be lots of exhibits and the Thunderbirds will put
on a show. You do need to submita waiver tothe AirForce releasing them ofresponsibility.Complete
details are not yet finalized but you can get information
from EAA39.org site.

Bob,
In southeast Missouri I always flew mid day because the airport was 37 miles
away. With the original ailerons, the FireFly could not be controlled in
roll. One had to kick rudder to help lift a wing and so flying mid day was
an exercise in dutch rolls. I found that I could not tolerate an hour or so
of dutch rolls and so mounted nine inch chord ailerons. They were
wonderful. With them the FireFly may bob up and down a little, but with
light stick side pressure, one could keep the wings level. It made mid day
flying very tolerable with out worrying about up chucking.
I have continued to fly at mid day as it is more interesting. If I am going
somewhere, I climb to at least 2,000 feet and mostly to 3,000 feet agl. There
I discovered the thermal and winter weather rolls are greatly abated. By
doing this there is only five to ten minutes of very active air that has to
be tolerated climbing up or gliding down.
The only time I do not feel comfortable in the FireFly is if I do not have
my shoulder straps snug. If I can feel my back coming off the sling seat
back, I get uncomfortable. During turbulent flight, if I do not move
relative the FireFly, I am ok. Weird things will happen, but a bit of
pressure on the stick and/or rudder usually set thing right.
One of the advantages of flying mid day with the thermals, is that you can
pick up about five mph ground speed by following a thermal street.

I have flown my MK III Xtra through mid day thermals, and it has never been a problem
in pitch. The MK III Xtra has very good control in pitch and have only
needed small fore and aft stick pressures to maintain level flight. I have never
ever even come close to using just half stick for pitch control in turbulence.
Roll control in my Kolb was to slow for me, I have never had to use rudder to get
the airplane to roll level in turbulence, but it was slower than I liked so
I added the Aileron Spades. With the addition of aileron spades on my Kolb,
it is very controllable in roll, but being used to flying airplanes with very
responsive ailerons, I am hoping to get a little better roll rate and lighter
roll forces with my wingtip mod which will keep any wingtip vortices off the ailerons.
Time will tell when I do this project.
Remember when flying in thermals, its not just air rising and sinking, the air
is swirling and moving all over the place in horizontal directions as well as
vertical, so some yaw and other weird movements will happen. I never see changes
in airspeed over 10 MPH in turbulence though. Gusts of 40 MPH are reason
not believe the airspeed indicator though, that kind of air movement would result
in severe turbulence even in a heavy jet, and would make a light airplane
unflyable, and is very very rare unless in a thunderstorm or other extreme and
rare condition. Heavier airplanes tend not to get thrown around so much in
turbulence, and the airfoil also has a big effect on this. As John H says, the
flat bottom Kolb wing loves to lift, and if there is a vertical gust, it will
lift the heck out of the plane immediately, more so than other wings ! With
a very high lift, slow speed wing, feeling the bumps comes with the territory.
I like flying in the mornings and evenings, I don't fly mid day unless I need to
go somewhere. Funny thing is my wife actually likes the turbulence, I can let
her fly in the worst mid day stuff I can find and she says she wants more.
One day I told her that is she likes turbulence so much that she should fly under
one of the many thunderstorms we have here in South Florida. She said she
would like to but had doubts as to weather the plane could handle it ! Here
are some pictures flying in some convection induced turbulence, if you notice
the airspeed, I do slow down for turbulence, it helps :)
