    You are a better pilot than me.>> Ha ha! Well done John. Best joke of the day so far. it is just that I am so concentrated on that last hundred yards, the height of the hedge, where the wind is coming from, is a sheep going to run into my path? am I clear of the electicity pylons etc., that after a quick glance at the ASI when I close the throttle as I turn finals I don`t have time to look at the damn thing. Circuits are fairly informal affairs at my farm strip. There are only about 9 or 10 of us on hangared there and visitors are few. Apart from always flying LH circuit everyone plans their own. I usually fly downwind at around 600ft,check for other traffic, lose about 100/150ft on the totally curved crosswind component and if everything works right I should straighten up in line with the strip with throttle closed, nose down, speed nailed, final glide established. I do not fly 5 degree `bomber` appoaches. If the engine is going to quit I do not want to be half a mile from the strip with 200 feet on the clock. Done that. Cheers Pat

    Chris, With this prop, the builder says that WOT in straight and level flight is only 3150 rpm. That is a little over propped but not by much. I'm thinking about eventually going down to 600-6 tires from the current enormous 800-6 tires since I don't land out in the boonies, at least not intentionally when I have an alternative. I believe that this will result in a big enough reduction in drag that the current prop may then be able to reach 3300 or at least a good bit closer to it. It that is the case then I won't be changing the prop. The noise from the ground in full power climb seems only a little louder than the 912 engines I'm used to. In the cabin, as long as I keep the RPM below 2700 it is not too bad. Full throttle climb at Vy is about 2950 rpm. My cruise rpm during my flight home was near constant 2688. -------- Thom Riddle Buffalo, NY Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x34 A complex system that works is invariably found to have evolved from a simple system that works. - John Gaule Read this topic online here: http://forums.matronics.com/viewtopic.php?p=255934#255934

    Coop, Man, I wish I had known there was a SS under construction at N38 because that IS where I stopped for fuel enroute home. I was there on Saturday around 2PM, I think. There was a red-headed guy at the pumps who told me there was a Kolb of some sort on the field but he didn't know which flavor. We are not that far apart (1.5 hours in a SS maybe?), so let me know when your is flying.

    The plans for the Mark3x say the bottom of the wing should be at +9 deg. when doing the W&B. The form that comes with the certification guide from EAA states the aircraft should be weighted in level flight attitude. My question to those who've had their Mark3x inspected ------ What attitude was used for your certification W&B ? And if it was level flight attitude, what is the level flight attitude.

    If you wanted to do some relatively simple math using the lift coefficient curve for a relatively thick flat bottomed air foil and the cruise speed of a Mk III you'd get the right result at an AOA of, wait for it, around 9 degrees.Set it just like the plans say, it works.

    Subject: Re: Weight & Balance for certification of Mark3x
    The flat bottom doesn't necessarily dictate AOA at cruise. Having many hours in an aeronca I can attest to the fact that it cruised on the step with the bottom of the wing pointed slightly down. Of the features on the Kolb wing that prevents this are: the thickness max is more forward of the aeronca's NACA 4412 and the nose is much sharper at the bottom of the leading edge. The piper J3 airfoil is closer with the max thickness position and the flight characteristics are more like the Kolb, high lift and draggy. (albeit a delightful low speed craft) If you want to pick up some cruise speed with very little sacrifice in other categories, build your Kolb wing with a much more blunt nose. That will give you more symmetry and better airflow. When you pull back and point upstairs the wind will take the easy way out and go underneath.

    Subject: HKS oil cooler damage
    From: Richard Girard <aslsa.rng@gmail.com>
    Just a note to the HKS flyers. I found out the hard way today that the HKS oil cooler is susceptible to cracking around the threaded fittings if it's mounted too rigidly. I first noted that the spacer on the mounting bolt was loose and after tightening it I noticed oil around the base of the fitting and along the top of the cooler. Tightened the hose nut, cleaned the top of the cooler and went flying. When I landed there was more oil. More cleaning, another snug up of the nut and more flying. More oil. Cleaned the oil off again and let stand this time. Pressure still in the system pushed oil out the crack. Hopefully a TIG welder can fix it or I'll be shopping for a new oil cooler. Now to figure out a way to suspend the cooler so it doesn't happen again. Fortunately the Yard Store has a great selection of dampers and shock mounts. Rick Girard

    My coolers are mounted on four 582 radiator shock mounts. I tried flying with two on top and hard mounting the bottom with a couple 6" long 4130 straps.

    I have some radiator shock mounts but there's no room for them unless I get new pipes to the muffler. I'll go out and take a few pics tonight. Maybe someone on the list can come up with a way I'm not seeing. Thanks John. At least I got 155 hours before it cracked.

    Subject: Freak accident
    I had an incident today I'd like to share both as a heads-up, and also looking for advice. When I came in today I taxied up to my hanger/trailer. I gave it a little throttle to get a bit closer and it seemed the engine didn't idle back when I pulled the throttle back. I put more pressure on the throttle to close it, and when I did, the engine revved up. Pressing the heel brakes kept it slow but I couldn't stop it and the right wing bumped the back of the trailer, putting a flat spot about 1" high by about 2" wide on the leading edge of my right wing about three and a half feet from the root. First, what I found out caused the mishap. Picture the throttle handle; when you push the throttle forward, the cable comes out of the cable housing straight forward. When you bring the handle back to idle, the cable re-enters the cable housing straight back. But when you move the throttle handle even further back (which is what I did in my sudden attempt to get the engine back to idle), it begins to pull the cable back out of the housing, straight down; which pulls the throttle on and you hit the trailer. To be forewarned... Now, the fix. There is nothing involved except a misshaped leading edge. I'm thinking if I get a piece of hardwood turned that I can slip into the tube from the root, when I reach the dent, I could gently tap it in and return the leading edge to the proper cylindrical shape. Kind of like the dies used to return an exhaust pipe to round. The wood is hard enough to bend the tubing out, but it won't scratch the inside of the tube as it's reshaping it. So, what do you think? Any input, cautions, other ideas, etc., will be enormously appreciated. Dave Kulp Bethlehem, PA FireFly 11DMK

    Not sure how your oil cooler mounts so this may not apply, but I have used rubber exhaust hangars for years to hold up the muffler with no problems. Buy them at Advance auto parts, grind off the rivet that holds them to the metal hangar strap, throw away the strap, keep the rubber. Cost about $3 a pair. Replace every third year.

Wouldn't the rivets holding the ribs to the leading edge prevent the wood from going in? Not sure it's an issue anyay. There's a similar dent on the LE of my UltraStar, was there when I bought it. Aside from cutting and peeling the fabric back around it to make sure there was no crack, I haven't worried about it. There's not a lot of stress on the LE tube anyway (it would be a very different story on something like a Quicksilver where the LE tube IS the spar). Sounds like what you really need is a stop to limit the throttle lever travel. -Dana -- "A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away." -Antoine de Saint-Exup,ry

I think the leading edges and the first 18 or so inches back to the main spar carry most of the load of the aircraft. One of the main reasons I put a lot of emphasis on keeping those little .028" wall 5/16" ribs in column by insuring there is more than enough lateral bracing to keep them in column. On your Ultrastar and my long gone FS, there are/were only 5 of those little guys carrying each wing panel. The leading edge tube on the Ultrastar was also shipped with .028" wall tubing. Old Kolb Company made a tool to push dents out of the leading edge without dismantling the wing. I put a big dent in the leading edge of my FS when a windshield split and departed the aircraft in flight. When I made the new replacement windshield I didn't know it was acrylic. I was told it was lexan. john h mkIII

Still, a shallow dent with no sharp creases in the front of the LE won't have a dramatic effect on the bending strength of the tube in the direction of the loads it does see. If the dent was on the top or bottom of the tube, or if there were sharp creases or cracks, I'd be much more concerned. -Dana -- "A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away." -Antoine de Saint-Exup,ry

    Would it be possible for you to send me a picture of how you mounted your cooler, I am having a hard time understanding how it cracked. Larry ----- Original Message ----- From: Richard Girard To: kolb-list@matronics.com Sent: Tuesday, August 04, 2009 5:58 PM Subject: Kolb-List: HKS oil cooler damage Just a note to the HKS flyers. I found out the hard way today that the HKS oil cooler is susceptible to cracking around the threaded fittings if it's mounted too rigidly. I first noted that the spacer on the mounting bolt was loose and after tightening it I noticed oil around the base of the fitting and along the top of the cooler. Tightened the hose nut, cleaned the top of the cooler and went flying. When I landed there was more oil. More cleaning, another snug up of the nut and more flying. More oil. Cleaned the oil off again and let stand this time. Pressure still in the system pushed oil out the crack. Hopefully a TIG welder can fix it or I'll be shopping for a new oil cooler. Now to figure out a way to suspend the cooler so it doesn't happen again. Fortunately the Yard Store has a great selection of dampers and shock mounts.

    Richard, Thanks, the cooler shares its mount with that of the muffler using a through bolt and a spacer to link the top and bottom mounting ears of the cooler on each side.

    John, I'm having difficulty with your concept of " the leading edges and the first 18 or so inches back to the main spar carry most of the load of the aircraft" The leading edge is connected to the spar by the ribs but not the the fuselage or the spar carry through. I just don't see the load path. Would you elaborate?

    Larry, I attached this pic to my reply to Richard Pike, but it really should have been here.
