    Subject: safety experiment
    Richard Stracke's recent posting started me wondering how many people have had a similar experience with an unintentional lift-off in a Kolb. I had attributed my accidental take-off to a gust, but Richard's use of the term "ballooning" seems to be a more appropriate term. I had been taxiing for engine testing, going at what I thought was a moderate, controllable speed. Probably about the same as one would use going down a taxi-way to the other end of a runway. I had been having engine trouble, with several distinct problems. At idle, there was a very heavy vibration- a shaking- that smoothed out above 2500 rpm. When I taxied the length of the runway- 900 feet or so- , and then went back to idle, the engine would "load up" and not promptly respond to throttle advance for a few seconds. Or, it would go the other way, and reduce rpms to 1400 or so, and nor respond at all until I shut it down and re-started. At the north end of the field, a couple of hundred feet from the end, there was an area that was slightly down hill, and would cause the plane to noticeably accelerate, even at idle. Sometimes I would have to shut off the motor to slow down enough to make my u-turn. I am not sure, but I think this is where my event occurred. My memory of all of it is still very shaky, more like a series of pictures than a flow of events. In order to help others stay away from a similar problem, I would like to enlist some help from the experienced members of the List. How slowly can someone make a very light Firestar take off? Or for that matter, what is the slowest lift-off speed of any of the Kolbs? My Firestar lifted off with a gross weight of about 475 lbs. , and about 2700rpm. What could be indicators of an imminent lift-off? How can ground speed be determined prior to such an event? Can a few of you take your plane and, on a long, safe area, carefully induce the plane off the ground and report the speeds and conditions? Maybe a GPS to determine it. Thanks Bill Sullivan

    Subject: Re: Any Examples of the new Valley Engine
    Jerb Valley had a new ultralight at AirVenture with the big twin engine on it. It performed very well on that light plane. It flew every day thru their full time period. They were expected to get this years yoyo award for the most takeoffs and landings. I was amazed that they were able to design and build a very refined airplane in only one year! I talked with Larry Smith for some time about their big twin engine on a Firestar II. Larry is convinced that almost any other prop other than a IVO would perform better. He is pushing the turbo option for this engine but said it isn't ready yet. He claims that the turbo will not over stress that engine. His explanation is that with the lower compression ratio of the turbo engine it sees no more ignition pressure just more duration. I don't know enough to comment. He feels that the turbo will make the Firestar II perform well even in that hot Texas air.

    Subject: Re: safety experiment
    William I have done this many times. It is a feature of all the current models of Kolb aircraft. Reduce the power any way you choose to when near flying speed and it will lift off. As I have said before some people have used this as a way to pop off the ground. Abruptly reducing the power while fast taxing will result in a very abrupt pitch up trim and it will get you air born. Someone that is inexperienced in this feature will get themselves in trouble doing this. I was taught in my private pilot training to taxi at a fast "walking" speed. This is a good rule for a Kolb. These planes fly very well and will reward you with flight if they get the chance. Never fast taxi if your aren't ready to fly. Also I think it is a very very bad idea to "crow hop" these airplanes as a way learning to fly. Again this is worth what you paid for it.

    Subject: Re: safety experiment
    Bill, Many pilots have found themselves accidentally airborne. Probably the more common scenario is to wreck trying to get it down on the remaining runway, rather than losing it on a landing attempt after going around the pattern. A related (and just as bad) situation is getting too high, or too far off the runway centerline, on an intentional crow hop. The minimum speed at which any aircraft will take off is, of course, its stall speed. For your plane that was probably somewhere between 25-30 mph, a lot slower than the Ercoupes you used to fly. The engine rpm is irrelevant if you've achieved flying speed; you could accelerate to flying speed, chop the power to idle, and pop the plane up into the air... though of course you won't stay up long. The rpm necessary to accelerate to flying speed on the ground is considerably less than that needed to stay airborne, since there is much less drag when the wheels and not the wings are supporting the aircraft's weight. Your engine trouble (rough idle and hesitation when the throttle is opened) sounds a rich mixture at idle. However, all single and two cylinder 2-strokes run rather rough at low rpm. Hope your healing is going well. Any thoughts on where you'll go from here, flying wise? -Dana -- End rush hour traffic now! Legalize vehicular weaponry!

    Subject: takeoff landing data on firestar and firefly?
    From: "grantr" <grant_richardson25@yahoo.com>
    Does anyone have any data on the Firefly and Firestar regarding takeoff distance and landing distance on grass. Also climb rate. I am looking at a house with some adjoining land however the longest leg is about 820 feet for the runway. There are trees on one end and more pasture on the other end. It may be possible to buy more land to extend it to extend it to 1438 feet. How many of you have private grass strips? What are the dimensions of the strip how far are the trees away from the centerline of the runway? I want to make sure to buy enough land so that if the neighbor decides to plant trees on the land line, it will not ruin my airstrip. Is an 800 foot strip long enough for either plane with 60 to 70' trees on the end? I was thinking 200' wide for the strip width Read this topic online here: http://forums.matronics.com/viewtopic.php?p=196688#196688

Mine is 319 lbs and stalls at 20 mph indicated. Since it's so light on the tail, I will go with full back stick and gradual full throttle. Once the plane is airborne, the stick goes forward or it will stall. This method isn't recommended for novices as they may not get the stick forward in time and end up stalling. This is my technique for crosswind takeoffs as the tail needs to be planted until it reaches flying speed or it will go off the runway. I would say the Firestar lifts off at 30 mph.

    So far, a fast walk is the best description of the safest speed to taxi. My sppeds at 2700 rpm were about running speed. I had had a one wing lift-off a couple of weeks earlier at about walking speed, caused by a strong gust coming in from my left. I thought I had a flat tire, or bent a landing gear- I had bent a couple of soft quality replacements prior to this (see the List under Firestar project). Another factor in generating lift-off speed might have been that the grass had been recently mowed. My only experience in observing ultralights taking off was watching Ed Harvey's Firefly, and Paul Gibney's Mitchell wing- but these were full power intentional take-offs. They had both observed my taxiing method, and neither had thought it fast enough to mention any hazards. I think the Firestar was deceptively large for it's weight, weighing in at about 307 with gas, and I only weighed 170 dressed. I think observers would think it would require a lot more speed to take off. The other known factor that day was weather. Temp in the 70's, completely overcast with clouds at about 1400 feet, some minor wind- enough to spin the sock around and lift it half way, then drop it. At lift-off it was overcast, but when I woke up looking at the EMT's face the sun was shining. Figure about 20 minutes total for the sky to clear up. I can't give a wind speed in mph for that. When more people check in, maybe we can get some kind of formula regarding gross weight, wind speed, wing area, and safe taxi speeds. Bill Sullivan

    Dana- I kow I wasn't going anywhere near 25 mph, but that doesn't count a stray gust. Like I said, about running speed (I think). Once it popped up, it went/rolled to the right- and there were marker cones, vent pipes for the old dump, and an embankment with a road. I had been told that if I ever got in trouble down at that end, to immediately go to full throttle and get away from the ground. Luckily, the engine didn't bog down, but that only delayed things for a few minutes. My vibration was a lot more than the other two 447's I'd seen; maybe motor mounts? Healing is progressing nicely. Still in a wheelchair, but can walk around a bit before lying down or sitting. The neck brace turned out to be totally unnecessary, as I had a lot of previous damage. I see the doctor in another 5 weeks. I will probably try to rebuild the Firestar. It will give me something to do this winter. My wife is continuing to take lessons up in Northampton, time and weather permitting. She took her most recent lesson in a CT Sport. She said it was a lot more sensitive than the Cessna. I can't do a full damage assessment on the Firestar until I can shift parts around. What I did see tells me it can be fixed. It wasn't ready to go in the air- The wings only had temporary hardware store multi-hole clevis pins in them! We will see. Bill Sullivan

I have my own grass strip which is 100' x 1300' long, but then that was the deal I had to make to lease it. it also met the minimum requirements to register the airstrip with the state and FAA. Look up 14PS on Airnav. com. The 100' wide is nice on cross winds especially with the tall corn on each side right now, but really not necessary. The 1300' long is more than I need or wish to mow! If I could re-negotiate the deal I would opt for 800' long. And yes, I have tall trees at the one end!!! Not a problem. I most always land in the other direction, but when wind conditions require, rather than coming in over the trees, I approach from a 90 deg. angle and then just turn and land. That's the great part of having a FireFly, it's ability to put down in not much space. The FireStar can do the same! Take off is about 200' to 300' depending on conditions and with a climb rate of 1000' a minute there is not a problem. You said you would have a pasture at the one end and that gives you a major safety valve. Hope this helps you, Terry - FireFly #95

Do you remember learning crosswind taxi technique, how to hold the ailerons depending on the wind direction? If you're taxiing fast enough to get the tailwheel off the ground, it's too fast unless you're on the runway, and prepared to fly. >... I think the Firestar was deceptively large for it's weight, weighing >in at about 307 with gas, and I only weighed 170 dressed.... > When more people check in, maybe we can get some kind of formula > regarding gross weight, wind speed, wing area, and safe taxi speeds. Well, you can use the stall speed calculations in AC103-7: Based on a wing area of 140 ft, which I believe is correct for the Firestar, and an all up weight of 477 lbs, the 103-7 nomograph gives a stall speed of 25 knots. Subtract from that the max gust speed and a reasonable safety factor, and you have a max taxi speed. >It wasn't ready to go in the air- The wings only had temporary hardware >store multi-hole clevis pins in them! Yikes! No WAY would I fast taxi any aircraft that wasn't ready to fly! You're even luckier to be alive than I thought. -Dana -- Politicians and diapers have one thing in common. They should both be changed regularly, and for the same reason.

    You engine problem has all the indications of being over rich. If you have the same problem again remove the air filter and try again. This will lean it out a bit. It maybe that all that is required is for the aircleaner to be cleaned. If it has been run at low RPM for some time the aircleaner may have a lot of oil in it.

    Tony- I have to table engine work until I put the plane back together, but I will save your notes. Thank you. The air cleaner was new, but did have a lot of low rpm running time- maybe 4 hours at or under 2700rpm. The other engine problem I don't think I mentioned was that after I changed from a 10 gallon tank (very dirty) to a clean 5 gallon tank was a drop in max rpm from 6500 (10gal.) to 6200 (5 gal.). I did keep trying to adjust the air and idle screws, but I don't recall the exact results. I made many, many trips down the runway and back while trying to fix the loading up, or bogging down, problem I had. Make a run, try it, shut down and adjust, and repeat. I didn't have brakes, so I had to stand outside with a foot on the strut and rev it up to 4000 or so to clear it. Then I'd get in, and repeat the taxi run to see if it would happen again. It was during this testing I had my lift-off. Bill Sullivan

    Good luck with the rebuild. I would suggest you tie the Kolb down and sort the engine out when you get your other problems sorted. With it tied down you can run the engine through its full RPM range. Its good to hear your mishap has not put you off. Get your self well, then attend to the Kolb . Good health and make your own good luck.
