Congratulations on your solo. You know you can never repeat that
experiance. Always be prepaired to leave tera firma when taxiing . I
have never flown a extra but the MK111 will lift off in that attitude no
problem. It just wants to be off the ground .

Subject: Kolb-List: Platypus Hop
To the rest of u it would be a crow hop (or negative Kolb Drop) but I
think my Xtra looks more like a platypus.
Since all I have is 2.2 hrs. legal instruction all I can do is taxi
practice for now.
I've taxied at 3600rpm and maybe 30 mph while keeping the tail hard to
the ground.
This time I was down wind at maybe 2600rpm and no more than 25 mph.
I released back pressure on the stick but still with full back trim.
This is actually neutral
elevator cause the prop just pushes it down. I just did this to keep
the tail wind from pushing me
all over the place.
Bada Bing my first solo flight. I couldn't believe it did a 3 point
lift off going that slow.
To my amazement I did'nt panic just held the stick where it was and
slight easing back of power.
Landed like a feather.
Now I know to experienced pilots thats a non event but to a 60 yr old
newbie that 3.5 second 6ft
altitude flight was monumental.
I was so tickled with myself I had to tell someone and then take a
nap.

Fellow Kolbers,
I've decided to sell my early Firestar. It is in need of some repairs as described
on the following web page.

After reading the numbers on the different VG installations I decided it
give them a try. Mark III/912...594 lbs empty...no flaps installed.
10 gas in main fuel tanks and 3 gals in reserve nose tank for test
flights. total of 13 gals.
W/O VG's 175 lbs pilot stall 44 asi ....W VG'S 36 asi power on
W/O VG'S 375 lbs duel stall 50 asi.... W VG'S 40 asi power on
31 VG'S total installed on wings 10 back from leading edge and set
between every other rib plus 3 on the wing gap seal
It also increased the rate of climb 200 to 400 fpm. Ground roll smoother
and shorter and landings much better and just wants to float in ground
affect, very soft landings. There maybe a 1-2 mph lose on cruise and all
testing was done in calm air
Worth the $35 including shipping off e-bay

Since everyon is posting #'s
1.1 hrs legal instruction MKIII xtra 912ul 590lbs empty
132 vg's on wing tip to tip including gap seal
Parallel on vertical stab 2" apart
200lb pilot, calm air, 75 deg.
Power off stall 37 ias 35 flaps
39 ias power on
100 ias WOT (5600 rpm) 400lbs of pilot and passenger, full fuel(10 gals)
Stall with 2, 45 ias power off
No more yank to left with power eased up on takeoff.
Pre vg's needed a little right rudder in level flight.
Now, slight to no left rudder needed. I'm just guessing but vgs must be
helping
trim tab work.
Landed 60 mph over the fence, forgot to look at touchdown.
It was so smooth that if the tires hadn't chirped you would'nt know you
had landed.
So Ellery you don't have to dive at the runway.
Especially with a mile of asphalt, not to be confused with ass fault,
thats just a crack.

| Subject: | Kolb List re: platypus hop |
- Vic- Be very careful!- I still have reason to believe that Kolbs can
be airborne at far below the published stall speeds.- When you lift off a
t extremely low speeds it would take only a slight breeze to overcome the c
ontrol established by the airflow.- Be very alert as to the direction and
speed of the wind, especially if it's variable.- I do not know how to in
itiate or recover from a crow hop, as I never asked about it.
- I now believe that I know what happened to me, and I don't think it was
as I first related.- I had my wife look at an aerial photo of the field,
and asked her where I took off, and what direction I was going when the li
ft-off occurred.- Apparently I had finished taxiing and had started turni
ng to my right when the left wing started the lift-off.- I had also been
in the habit of keeping the stick firmly to the rear while taxiing.- I ha
d also gotten into the habit of using the ailerons to counter any leaning w
hile making a tight turn.- In the Firestar the stick had to go forward to
accomplish this- all the way back, it was trapped in the "V" of my legs.
- The tail popped up with the stick forward a bit, and right aileron.-
I immediately pulled the stick back to put the tail down, and the plane pop
ped up while heading for an embankment with vertical vent pipes.- As I ha
d been advised, I went to full throttle, and the Firestar climbed at an
incredible rate and steep angle.- This part had always confused me, beca
use I had looked down and saw trees that I knew were off to the right.- N
ow I know that the lift-off had caused a turn that brought me to an angle o
f more than 90 degrees to the right of the runway.- I noted the ASI was i
noperative, and brought the nose down to avoid a stall.- I took it up to
750 feet- no more, as the cloud cover was about 1200.- I leveled out and
throttled back to about 5500 to make a turn to my left and re-align with th
e runway.- The air was very rough.- I decided to make a fast pass at th
e runway to check handling.- I couldn't have asked for a sweeter handling
plane- no quirks other than the sensation of sitting in the nosecone of a
missile while climbing!- After the fast pass, I checked the windsock- lit
tle wind.- I circled around to line up with the runway, and decided to-
fly in on.- Rpm's were 5000, and I aimed it for a touch-down spot.- Sp
eed
unknown, but it stayed aimed at that spot.- When I got a couple of feet
off the ground it seemed to go into ground effect, and "floated".- I now
know that instead of cutting back on the throttle, I forced it down by push
ing the stick forward.- The right gear bent back, and the nose hit, cartw
heeling.- I don't remember impact, or crawling out after my wife ran over
and released the seat belt.- Next thing I saw was an EMT looking down at
me.- No pain, but dirt in my eyes.
- I would rate the accuracy of the above at about 80% or better- some is
guesswork, and some-I remembered just as I woke up one day about a month
ago.- In all probability, what I thought to be a gust was just the sudden
lift, or an assist from a slight gust.
- Advice for beginners:- Don't do what I did- high lift wing, and no br
akes.- I had told everyone I was a beginner, but I don't think I emphasiz
ed it enough.- Ignorance was my biggest mistake, and possibly complacency
.- Get someone else to try taxiing your plane before you do, and make sur
e they are about the same weight.- Let an experienced pilot give you the
safe RPM's to taxi.- I had been observed by experienced people who knew I
was an beginner, but they did not think I was going too fast.- Appearanc
es can be deceptive.- Always use the seatbelt/harness, every time the mot
or is running (I did- habit).- If you don't have a radio, and know how to
use it, bring a cell phone with the number of an experienced pilot (I didn
't- I was being a mechanic, and saw no need for it).- Another mistake I m
ade-- I went up with a full tank of gas, and came back with it.- The pl
ane didn't fall apart in the first 5 minutes, so I should have used it to r
eally
get comfortable with the plane.- I had a BRS, and if it was going to do
something drastic I was at an altitude to use it.- I ended up landing ups
ide down with a full tank- no spillage, but might have saved me some pain i
f I had gotten-a little more familiar with it.- Bring a watch- I didn't
.- No gas gauge, and no communications, so I didn't know how long I had.
- Later found out the flight was only about 8 minutes.- I also should h
ave kept the nav bearings for a long field on me, as the field looked quite
short for a beginner in trouble.- This may have influenced my decision t
o stuff it in.
- I had just taken my first refresher flight in years, and I goofed again
.- When the instructor asked me what I wanted to start with, I said, "fam
iliarization and orientation" (What's this knob do?, and Where are we?).-
I should have shot touch and goes, which is where I left off 40 years ago.
- Anybody else have something I missed?- I deeply appreciate any and al
l criticism and additions, especially for the benefit of any lurkers or beg
inners.

Bill S:
There are no "official" published stall speeds for Kolbs, that I know of.
Most all are a little different based on weight of airplane and pilot.
Airplanes do not fly below stall speeds.
I mentioned to Vic the other day on the Kolb List, taxi speeds, to me, are
perceived ground speeds of a fast walk or less, not 25 to 30 mph. Anything
faster than that, and you are either transitioning from a landing or takin
g off.
High speed taxiing in an unfamiliar airplane by an unqualified, untrained s
tudent pilot from 40 years ago, is an accident that will happen. I believe
you mentioned you were a very low time student pilot, but I may be mistake
n.
I think it is readily evident why you crashed, you don't know how to fly.
How you crashed is irrevalent.
Right now I can not think of one good reason for you to be in the airplane
running up and down the airstrip in the first place. But I am sure you can.
If I was in your shoes, I wouldn't think of getting in another airplane unl
ess there was an instructor pilot in there with me.

- John- I agree.- We (the students) were given permission for slow taxi
ing.- I would not know how slow was slow, or how fast was dangerous.- I
am listing every possible mistake I've made so that other's won't make the
same ones.- Please continue with the comments.-

Vic,
Way back in '06 when I soloed I did some high speed taxiing... I had Jim Hefner
post my an account of my experience. So as not to bore the rest of the rest of
the list with my sillyness I've attached a link to that posting. My comments
are the second post in the thread... And my thoughts on high speed taxiing haven't
changed.
http://forums.matronics.com/viewtopic.php?t=16310&highlight
Also... If Dr.Hauck were to pontificate on my flying... I'd genuflect smartly and
proceed as advised.
Good luck. I hope you're flying soon. It's the second greatest thrill known to
man... Landing is number one.
Aloha,
Henry Voris
