What you lose in glide ratio you get back in the ability to use a small field. A BRS is for structural failure, NOT for an engine failure! In the event of an engine failure, you need to get the nose down NOW to maintain flying speed, because the plane is so light (and counteract the pitching tendency when that high mounted engine stops pushing), but then you're fine. Dual is good, in at least something similar. It was some 15 years since I last flew my Taylorcraft (or any other plane), a few hours in a 2-place Quicksilver with a friend, and I felt ready to fly my Ultrastar. Except for the landing speed and the need to flare at six inches, not six feet, a Kolb flies more like a T-Craft than a Quicksilver. Dana -- Space isn't remote at all.

It is certainly possible to run a 3 blade 68" Ivo on a 503, my only question would be - what was your cruise speed, and what rpm were you turning at that speed? In order to get the 503 to turn 6500 rpm, you will need to take out a lot of pitch, and then then your cruise speed goes to pot. Back when I had a 532 on the MKIII, I started out with a 64" 3 blade Ivo. Given that the 532 did not have as flat a torque curve as the 503, still, in order to make the engine run properly, I had to run it with the prop in fairly flat pitch and it had a great takeoff and climb, but at cruise it was turning 5800-6000 rpm with poor airspeed. Around 62 if I remember right. Took away one blade, repitched the prop, and the cruise rpm became sane, cruise speed went up, and it kept it's good takeoff and climb behavior. With the 582 and a 68" 2 blade, cruise speed is 65-70 at around 5500 rpm and 4 gph. Takeoff is typical Kolb - great. -------- Richard Pike Kolb MKIII N420P (420ldPoops) richard (at) bcchapel(dot)org Kingsport, TN 3TN0 Now faith is the substance of things hoped for, the evidence of things not seen.

Other than a slight degradation of the glide by the prop (mine has a three blade Warp Drive) my Mk III was no different from landing it with the engine at idle. If you do this, though, "collective down, stick forward, maintain rotor rpm till just above the ground", you will definitely make problems for yourself.

Its nice if a wing falls off but unless you fly over some totally unlandable territory an ultralight has so little inertia and flying speed is so low that you can usually find a usable spot. if it is just an engine out just fly the plane to the ground.You are in control.

You're in an emergency situation where things have gone to junk as a result of your action or inaction and now according to the BRS theory you will do something you have never practiced, cannot preflight for, and do not know the outcome of should you do it. Case in point. The airplane from hell was recently sold to a fellow who has a small runway on his property. According to what we know, the engine failed on take off and the new owner flew it into a line of trees at about 30 feet off the ground. He may be out of the hospital now, we don't know. The point is that he had the BRS handle right by his left knee and did nothing with it, even though such a scenario is within the BRS safety zone, according to BRS anyway.

Rick Girard Rick G/Kolbers: Yes, I would use my BRS if the need arises. I practice and have engrained into my mind what to do should the need arise. I also preflight the system, ensuring the safety pin is removed and the bridals are in good shape. I have faith in the system. Quite a few folks have died because they never thought of their parachute before they hit the ground. When something catastrophic happens, one must react instantly in most cases. A split second may make the difference between success and failure, life and death. Some situations the parachute probably will not save you, such as the recent crash Rick G mentioned. No matter, if I wasn't flying, I would not hesitate to pop the chute. john h mkIII Rock House, Oregon - Two time member of the Caterpillar Club. ________________________________ Message 10 ____________________________________ Time: 12:50:20 PM PST US From: WhiskeyVictor36@aol.com Subject: Re: Kolb-List: Re: Pre-Purchase Inspection, Firstar John h And just what is this Caterpillar Club?

From: "wakataka" Below is a link to a video shot from an original Firestar. The last minute or so shows a deadstick landing from base leg at about 500 feet agl. The glide angle is not extreme. In fact, I can't tell much difference between glide angle at idle and deadstick. I think what trips up a lot of pilots transitioning to ultralights is the ground rush during the last few feet of the descent. If you're not used to the wide visibility and the low to the ground seating position, it feels like the earth is rising up to smite thee and the temptation is to round out too soon. Without the engine to provide a burst of power, that can result in dropping it in from several feet up. The trick is to fly it right down the ground before beginning to roundout and flare. http://www.youtube.com/watch?v=9uOCAwEj8VQ -------- There is something fascinating about science.
