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 at extremely low speeds it would take only a slight breeze to overcome the control 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 initiate 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 lift-off occurred. Apparently I had finished taxiing and had started turning 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 had also gotten into the habit of using the ailerons to counter any leaning while 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 popped up while heading for an embankment with vertical vent pipes. As I had been advised, I went to full throttle, and the Firestar climbed at an incredible rate and steep angle. This part had always confused me, because I had looked down and saw trees that I knew were off to the right. Now I know that the lift-off had caused a turn that brought me to an angle of more than 90 degrees to the right of the runway. I noted the ASI was inoperative, 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 the runway. The air was very rough. I decided to make a fast pass at the 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- little 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. Speed 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 pushing the stick forward. The right gear bent back, and the nose hit, cartwheeling. 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 brakes. I had told everyone I was a beginner, but I don't think I emphasized it enough. Ignorance was my biggest mistake, and possibly complacency. Get someone else to try taxiing your plane before you do, and make sure 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. Appearances can be deceptive. Always use the seatbelt/harness, every time the motor 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 made- I went up with a full tank of gas, and came back with it. The plane didn't fall apart in the first 5 minutes, so I should have used it to really 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 upside down with a full tank- no spillage, but might have saved me some pain if 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 have 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 to 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, "familiarization 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 all criticism and additions, especially for the benefit of any lurkers or beginners.

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 taking off.

High speed taxiing in an unfamiliar airplane by an unqualified, untrained student 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 mistaken.

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 unless there was an instructor pilot in there with me.

John- I agree. We (the students) were given permission for slow taxiing. 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.
Thank You

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

William ,it is great to to hear from some one that is so open and willing to share their mistakes so others may learn. It is also really good you did not damage your self beyound repair. I can understand the desire to aviate and find it difficult to chastise anyone that finds themselves in a place they would rather not be . Have been there, like the day I hit a real southerly front and went from 500ft to 1500 in the bat of an eyelid then lost the same 1000 just as fast. The spare helmet was glued to the cockpit roof . As I was flying directly into the wind I desided to head home , from the time I started the turn to the timr I came out of it I had covered about 1 mile .Arrived back at the airport and had to use full throttle ,stick hard forward just to get to the ground. Good thing some flying savy people were there when I landed. Very short landing roll ,touch ground ,kill the power and stop. The people that watched me come in were there to grab the wings, drape a body across the tail boom and assist me back to the hanger . The tower gave a gusting wind speed of 35 mph when I landed . that is about my stall speed . The game we play can be very unforgiving . Did I learn anything from my experiance, well yes ,just because the weather was really calm when I took off the indications were there that it was going to change, so I should have used my judgment on the weather as opposed to my desire to go flying and I also learned that Kolbs can fly backwards, as I was on short finals and reduced power the runway was getting further away.

Many regards

Tony- Now that is scary! I was at a small air show about 25 years ago, and a demo pilot from Pioneer Parachute was flying one of their chute equipped ultralights. The wind was blowing strong but consistant straight down the runway. He adjusted his throttle, and hovered about 30 feet up for about 10 minutes. He would have had no trouble flying backwards.
I had made the exact same run about 50 times without any trouble. Same rpm, equipment, etc. This is why I believe a gust was responsible for the actual airspeed necessary to lift off. I had a full enclosure, so I never felt wind. The vertical embankment was only about 30 feet away. and went up maybe 12 feet or so. The runway sits in a man-made depression at an old dump.
John re-capped my previous experience. I had taken lessons for a short time about 40 years ago, but stopped because of an injury. I was starting over again, now that I had the time and money. Once again- I am not a pilot!!!
I grade my memory at only about 80% sure because I was knocked out, and the memories are fragmented. I would rather be criticized than have to go to somebody's funeral. Been there, done that, and a friend was very messily dead. He got hit by a car while attending to a broken down truck- not alert enough. Sometimes warnings aren't adequate, sometimes things just happen.

Bill, At least here on the forum, I see no one has answered your question about how fast to taxi. I'll give you the answer as it has been drilled into me by every flight instructor I've ever trained with. Walking speed. Taxi as fast as you walk. Not jog, not trot, not run. Walk. Which makes taxiing about as much fun as riding a garden tractor, as it should be. If your instructor didn't explain this to you, give serious thought to finding a new instructor. If he didn't give you explicit instruction when he released you to do slow taxiing, in what else has he been remiss?

How fast I taxi depends on whether the harness is snapped on...   Smile-but seriously, there are factors, such as gusty conditions (a crawl)
pavement: slow because of weak brakes, more twitchy tail reaction.
my long grass: go for it, get a thrill!

How about we keep it as simple as possible for the beginners. Taxi speed equals walking speed.
Another one that I did pick up from the List- Keep the stick back and apply power gently when starting to taxi, otherwise the Kolb might nose over.

I get the impression you are trying to learn to fly on the Kolb List. This would be the last place I attempted to learn to fly. First place I would go would be a competent flight instructor.

If I am wrong, promptly correct me and I will get on with my chores.

I'm a lurker here myself, and it appears Bill S. is not trying to learn how to fly here on the Kolb List, but simply gain helpful advice and ideas. If I had my own Kolb and was just learning how to fly it I would definitely have an instructor to show me the straight and narrow, but even still the wisdom of you all would be very helpful and informative.

I enjoy reading everyones advice and techniques, since i don't have a Kolb to play with myself Smile

John- I am not looking to learn to fly here, except for peculiarities to Kolbs. My intent was to learn from scratch in an LSA ( a CT Sport out of Northampton, Mass.), and then transition to an ultralight, then to the Kolb. If we ever get some good weather, I'll start again. They just got a new CT.
I was trying to get you and others to give the lurkers some basics, especially pertaining to the Kolb types. Sorry you misunderstood.
I would like to hear of incidents and mistakes by others, so they can be averted.
Also, how on earth did you manage to deploy that hand-held parachute? Tell more stories, please.

Bill S:

Think you are getting the horse before the cart.

Learn to fly with a competent instructor.  Get a little air sense. Go through Ground School. Seems that would be a good thing to do since you are busted up at this time, and can probably handle the class room work. Learn the basic terminology of aviation, aircraft, and flying. That is the normal place to start. After you learn to fly, then you can get familiar with type.

Nothing peculiar about Kolbs. They are little conventional three axis controlled aircraft. The differences between other models of GA and experimental/ultralight/SLA aircraft pertain to Kolbs as well.

The Kolb List Archives are full of "incidents and mistakes by others", yours included.

I think both hand deployed parachute saves are in the archives. If not, I'll share them with you the first time we meet.

I am not trying to be critical of you. I am trying to get you to see "reality". If I am headed in the wrong direction, let me know and I'll go do my chores. Wink

Gravity is not prejudice. It affects me same as it does you. I too, have discovered several times, the earth is very hard.

John- Not really getting it backwards, just had the opportunity to purchase the Kolb, and was starting the instruction. Remember, I'm not in a hurry.
I have always had a lot of trouble with gravity. Every time I drop something it goes ALL the way down. I am considering suing the estate of Isaac Newton. We never had this kind of trouble before he thought up laws for gravity. They have all that money from all of those fig bars, anyway. I can sue- it's my right as an American.
Love to here the detailed stories. One of these days, John. Meanwhile, I'll poke around in the archives.

BillYou're quite right about keeping the stick back to avoid a nose-over. BUT with a headwind,  if a strong gust on the nose hits you, you'll be airborne instantly. If the stick is forward, a gust will simply lift the tail
Also, with a strong tailwind and the stick back, the wind hits the underside of the elevators and can cause a nose-over
Every situation is different but this is something to keep in mind.
Keeping the stick back all the time isn't good advice.

You're quite right about keeping the stick back to avoid a nose-over. BUT
with a headwind, if a strong gust on the nose hits you, you'll be
airborne instantly. If the stick is forward, a gust will simply lift the tail
Also, with a strong tailwind and the stick back, the wind hits the
underside of the elevators and can cause a nose-over
Every situation is different but this is something to keep in mind.
Keeping the stick back all the time isn't good advice.

Crosswind taxi technique (really, not crosswind but any wind direction) and
where to hold the stick for the various directions is a basic technique,
taught to all students before solo... at least, before INTENTIONAL solos!

John, All these re:, RE:, SPAM re:, etc make conversations hard to follow and sometimes they get updated in the darndest order. All I had was Bill's how fast to taxi question at the time I responded. As for how much info Bill did or didn't get on an orientation flight, his statement:"We (the students) were given permission for slow taxiing" implies the instructor gave his endorsement to the activity, does it not?
There is nothing in FAR 61.87 or 61.195 which allows an instructor to release a student for solo taxiing. The student doesn't do anything in the airplane solo until he/she is signed off for solo flight.

Think you are getting the horse before the cart.

Learn to fly with a competent instructor. Get a little air sense. Go through Ground School. Seems that would be a good thing to do since you are busted up at this time, and can probably handle the class room work. Learn the basic terminology of aviation, aircraft, and flying. That is the normal place to start. After you learn to fly, then you can get familiar with type.

Nothing peculiar about Kolbs. They are little conventional three axis controlled aircraft. The differences between other models of GA and experimental/ultralight/SLA aircraft pertain to Kolbs as well.

The Kolb List Archives are full of "incidents and mistakes by others", yours included.

I think both hand deployed parachute saves are in the archives. If not, I'll share them with you the first time we meet.

I am not trying to be critical of you. I am trying to get you to see "reality". If I am headed in the wrong direction, let me know and I'll go do my chores. Wink

Gravity is not prejudice. It affects me same as it does you. I too, have discovered several times, the earth is very hard.

John-

I am not looking to learn to fly here, except for peculiarities to Kolbs.

I was trying to get you and others to give the lurkers some basics, especially pertaining to the Kolb types.

I would like to hear of incidents and mistakes by others, so they can be averted.

Also, how on earth did you manage to deploy that hand-held parachute? Tell more stories, please.

That's why I attempt to cut and paste referenced msg. Hopefully, I leave enough of the original msg so folks know what I am talking about.

Neither of which apply to Part 103 ultralights, which is what Bill [accidentally] flew.

Still, I seem to recall (been a long time, I could be misremembering) my instructor having me taxi the C-150 over to the fuel pumps alone before I soloed, if the plane needed fuel and he had something to do before flying with me.
