Sincerely, Dennis Rowe, Mk-3 N616DR, PA Morning Dennis/All: I used streamlined 4130 struts on my Firestar and initially on the MK III. One strut was destroyed during the initial testing crash of the MKIII. 4130 streamline tubing is very expensive. I didn't have the money to buy more. When I rebuilt I ruined two sets of extruded aluminum streamlined struts attempting to drill the bolt holes for the lift strut end fittings. For some reason I could not get them drilled correctly. I ended up having Brother Jim weld me up a lift strut of 4130, .058 wall X an inch, or whatever the inside diameter of the alum strut is. Then I used the alum streamlined strut over the round 4130 tube for drag reduction only. The streamlined struts are secured with a couple 1/8 rivets on each end. I get called on this occasionally. Folks want to know if I am comfortable with the attachment of the lift strut fittings with so few 1/8 rivets.

Larry B/All: Be amazed no longer. I just looked at your web page reference adjustable rudder trim. Looks good. I use a simple rudder trim tab. Once adjusted correctly for yaw trim at cruise, I find that it is "set and forget". Cruise flight is the most annoying period of flying that requires some help in the yaw department. Other phases of flight in the MK III are very short, for the most part. We climb fast, descend fast. Sorta whip right through those areas............. john h PS: Hope you feel better. ________________________________ Message 13 ____________________________________ Time: 09:45:32 AM PST US From: CaptainRon Subject: Re: Kolb-List: Re: Jury struts --> Kolb-List message posted by: CaptainRon Does anyone have any figures on the -g loading of the stock M3X.

If I had known about then when I was building, I would have included then on my Kolbra. With the Jabiru engine running at 2900-3000 rpm, a harmonic vibration is set up in the lift struts that can be felt through the airframe, seen very clearly and can be heard if you listen closely. I think the jury strut could eliminate that vibration. I'm not going to open up the wing to install them but if I ever have to open the wing for any other reason, a set of jury struts will go on.

Here is what I did and the results. I used Jack Hart's design. I originally did not taper the vertical "legs" of the VGs but then decided they looked better tapered so I ended up doing it after all. Take-off Wt: 537# Before VGs: T/O speed in 3-point stance: 32 mph IAS Stall speed power off: 30 mph IAS Stall character: mush First VG Test: VG location: Front of each VG 11" from leading edge, in each valley between ribs, 19 on each wing. T/O speed in 3-point stance: 30 mph IAS Stall speed power off: 27 mph IAS Stall character: abrupt I did not like the abruptness of the stall so I decided to relocate them in a tapered pattern. Based on the approximated curvature of the upper surface of the wing, I calculated that the tangent point would move about 1/8" per degree of change of AOA. Since the 3-point stance has an AOA of about 11 degrees I figured I would have the tapered location of the VGs run from tangent at 6 degrees to 16 degrees. Therefore I located the front of the outermost(nearest wingtip) VG at 10 3/8" from the leading edge and the inner most VG at 11 5/8". I then strung fishing line between these and placed the others along that line. I had no idea if this would work but apparently my reasoning was sound because it improved the stall behavior w/o sacrificing much in stall speed and nothing in T/O speed. Second VG Test: VG location: as described above T/O speed in 3-point stance: 30 mph IAS Stall speed power off: 28 mph IAS Stall character: crisp but smooth I then wanted to see if roll and pitch control could be improved as I've read in other's reports. So I added VGs in front of the ailerons and on the bottom leading edge of the horizontal stabilizer. Third VG Test: additional VG location: I added 14 VGs to each wing about 3" in front of the ailerons. I put them directly in line with the false ribs so they would not be directly behind with the forward VGs. I also added one about 9" from the wing tip. I placed five(5) VGs on the bottom of the each side of the horizontal stabilizer evenly spaced (about 9" apart) just behind the leading edge, like Jack Hart shows on his website. I was going to put some VGs on the vertical stabilizer but ran out because I used more on the ailerons than I had anticipated. Results: The roll control and pitch control before were not bad but not great either. With the additional VGs the roll and pitch control in very slow flight is now as good as I had on the Zenith 701 I used to own and that aircraft had the best slow flight roll and pitch control of any aircraft I've ever flown in my 36 years of flying. When landing I came in rather high as is my custom and had to slip to get it down. It now slips much better and I had total control in a steep decent (well as steep as you can get w/o flaps) slipping dramatically at an IAS of 35! Conclusion: The VGs on the ailerons and horizontal stabilizer enabled much more precise control in slow flight. For those interested in trying VGs on their Kolb, I would definitely do these first. The improvement was really dramatic. The tapered pattern, I believe, improved the character of the stall w/o sacrificing absolute stall speed enough to care about. The tapered pattern did not increase or reduce the 3 point stance t/o speed as compared to the straight across location.

Running at high RPM forces the uses of short prop to keep from going super sonic - then your RPM limit restricts the amount of power you can extract out of the engine. With a redrive you can run the engine at higher RPM to generate the power and with the redrive slow the prop down to turn a larger diameter prop for greater efficiency. Trying to run Subaru's direct drive you run into the same problem. jerb At 09:52 AM 10/29/03 -0500, you wrote: >--> Kolb-List message posted by: Bob Bean > >It would be interesting to see a list of the variety of powerplants that >have >propelled Kolbs through the years, including the chainsaw engines. >You would have to be innovative to get much power out of the two-banger >vw.

My friends N3-Pup the tail would just shake violently while the engine was at slow idle. Once you brought up the RPM some it would smooth out. I don't think you could pull 50-60 house out of 1/2=VW that would hold together for long. 40 HP would probably be about the best you could get. jerb At 05:47 PM 10/29/03 -0800, you wrote: >--> Kolb-List message posted by: "Larry Bourne" > >As Rick said, and has been said before - the VW needs a re-drive to get its >RPM's up, and a prop to match.

I use Bostick brand, which is a copper color (and just as messy as Permatex), and have used it on automotive and marine exhaust manifold nuts for years. Never had one stick, or come loose prematurely. The stuff is truly worth the money. For you home handymen; I use it at work on all outdoor electrical boxes, and now the other guys have been converted, too. Putting an EMT or Liquid Tite fitting in a Bell box without anti-sieze (or even a little ordinary grease) will guarantee it to corrode into a solid chunk in a year or 2, requiring you to destroy it while trying to fix it. I will check out your stuff, tho'................my can is nearly empty. Pity..........it only lasted about 7 or 8 years. Lar. Do not Archive.

Got some parts back from the machine shop and the exhaust pipes are now progressing. Will cut the rest of the pipes this weekend and have them welded up next week. I just might fly with the Verner 155M before Thanksgiving. With the different rpm range with the new engine and the three blade prop, my lift struts might not vibrate anymore.
