I use 1.125 X .125 4130. Heat treat to RC48. Here is a metal treating company I have used in the past. They had a plant in Anniston, AL, last time I had a heat treating requirement, but looks like they have shut that plant down: http://www.braddockmt.com/ You can do a Google search for "metal treating" or "heat treating" and come up with lots of places to get the job done. I find it much easier to fabricate and fit the gear legs with axle sockets welded on, wheels aligned and all holes drilled prior to heat treating.

Hart" Subject: Kolb-List: Re: The Kolb Drop Kolbers, I wondered about the term Kolb Drop. Is it fair or proper to give Homer credit for this phenomenon? I checked the FAA Preliminary Accident and Incident Reports for Feb 19. Out of 38 reports, I found five were listed as outright crashes while the aircraft was away from an airport. The transition from the air to the ground and movement on the ground seems to give pilots a lot of trouble. Eight pilots had trouble keeping their aircraft aligned properly with the runway which resulted in nose overs, ground loops, slide offs, hitting snow banks and taxiing problems that killed several runway marker lights. Birds sacrificed them selves to three aircraft. And finally, eight pilots impacted their aircraft so hard that only three could taxi away from the runway. Not one of these aircraft was listed as a Kolb. These data indicate that it must be more difficult to land and taxi GA and commercial aircraft than Kolb designed aircraft. May be Kolb Drop should be redefined as Earth Jump. Earth Jump can be equally applied to all aircraft with out giving undue credit and it easily explains away why the earth is not in the correct position when these pilots flared or were repositioning their aircraft. All aircraft are equal when they are on the ground and humans are absent. The snow is slowly falling. Fly safe. Jack B. Hart FF004 Winchester, IN do not archive Only an idiot would not recognize there very real fact. I have instructed in the Kolb, and as a CFI in general aviation aircraft. ............... Kolb's have the characteristic of suddenly dropping hard on landing if very good technique is not used. Cessna and other most other training aircraft are not like this, they are much more forgiving on landing and tolerant of the pilot being a little off speed, or a little high in the flare. Only an idiot would not recognize there very real fact. I have instructed in the Kolb, and as a CFI in general aviation aircraft. In General aviation aircraft, I can let students get much further off speed, or flare a lot higher on landing than in a Kolb, and not bend the gear or result in a very hard landing. Hundreds of students flare high, land slow, etc etc every day in Cessnas and other aircraft and you do not constantly bend the gear, partly due to stronger gear, and partly to do much more forgiving aerodynamics. ________________________________ Message 5 _____________________________________ Time: 07:37:58 AM PST US From: "John Hauck" Subject: Re: Kolb-List: Re: The Kolb Drop > May be Kolb Drop should be redefined as Earth Jump.

I think the main problem here is that the Kolb drop is not recognized for what it really is....the wing quits generating sufficient lift and is stalled....plain and simple. The difference between a Kolb and heavier aircraft is that it slows down a lot quicker, so you do not need to flair as early or as high as with the heavier aircraft. An extreme example would be the space shuttle landings.....they pitch the shuttle up to start the flair for landing a half mile away from the intended touch down point. Also the Kolb does NOT have shock absorbing landing gear, so you do not want to subject it to a full stall landing from any height as dropping it in is going to hurt the Kolb and perhaps the pilot. Nuff Said....get used to your Kolb and fly it accordingly. If you keep doing something painfull...then STOP doing it and try something else.

It's been done ! Was talking to a certain KOLB pilot one day at a fly-in and was discussing the Mklllxtra and the pro's and con's of fitting VG's when this admission came out. The resulting test stall 'maneuver' was, as he put it, 'very interesting !' I've just checked a definition of 'maneuver'. It says " A deliberate coordinated movement requiring dexterity and skill " Not so sure that 'maneuver' is the correct word now. Yes it was deliberate but I'm not so sure you could call the event 'coordinated' although it did, no doubt, require 'dexterity and skill' in the following recovery. Anyway, the VG's are on both wings now that his curiosity is satisfied, and I got the distinct impression that he's not going to do that again. If that particular KOLB pilot (who monitors and occasionally contributes to the list) wants to post some info on this but still remain anonymous [Wink] , then please contact me off list and I'll 'cut 'n paste' your reply .

I lost around 3 or 4 mph cruise with them. Hopefully, I will find an airspeed that makes good use of the VG effect and increase my range by lowering the rpms required to give a slower and more economical cruise. I would like 60 mph at a fuel burn of 2 gallons per hour. Probably the VG effect will not happen until the airspeed lowers to around 50 mph. Need a wind tunnel. ________________________________ Message 9 _____________________________________ Time: 09:23:00 AM PST US From: gary aman Subject: Re: Kolb-List: Re: The Kolb Drop Maybe a little refresher course on gravity and airspeed would be helpful if they are having difficulty with the earth jump concept.Someone said the earth sucks when you get that close to it. ----- Original Message ---- From: John Hauck Sent: Wednesday, February 20, 2008 7:35:13 AM Subject: Re: Kolb-List: Re: The Kolb Drop --> Kolb-List message posted by: "John Hauck" > May be Kolb Drop should be redefined as Earth Jump.

The more important point is that VG"s make the Kolb Drop much less severe. Pilots are human, no one lands perfectly all the time. VG's can make the difference between bent gear, and just a less than perfect landing. I would much rather have plane that is more forgiving on landing, rather than one that probably result in damage the first time I flare a bit high. It is obvious that the people that are saying VG's don't make landings in a Kolb much more docile are the people that dont have VG's.

If you disagree with one of the members of this small group, there is a quick negative public response by them.

Mike, I have the plane that John H flew with the VG's. They are ones that I built myself using the formula that Howard Shackleford presented to this list long ago when VG's first appeared on this list. The stall on this Firestar has dropped to 32 MPH from 46MPH. Straight and level at 6000 rpm's shows 70 MPH on a GPS. I don't think I lost any speed, but I sure increased the time that I can fly while flaring. I like it, a lot. I have bent my share of gear before I installed the VG's. John doesn't see the need to do that to his plane. I don't have a problem with that! I don't think that he is being dishonest or attempting to say that I am a sissy because I choose to use them. For what its worth John is a much better pilot than I am, more experience, more time generally adds up to better skills. As for the VG flight test that occurred between John and Richard, I am afraid that it was not a very valid test. John did his considerable best, but I think that Richard will tell you that he could have pushed the envelope a bit more had he felt more comfortable in flying that close to another airplane. Where the problem shows up is when people cannot accept that not everyone sees the same answer to the same question. Where the problem shows up with you Mike is quite frankly your choice of words. Every time that "Idiot" or "plain stupid" shows up in one of your messages, the meaning is lost, every thing is lost except the knowledge that we who are reading it and might have a divergent view have been disrespected. If these same views were expressed face to face, I suspect that you might receive a bit more of a personal attack than a verbal one. Opinions are a lot like assholes, every one has one and few see the need for two. Lighten up a bit!

Geez, there are some people who find a straight forward stall to be a problem, so for gods sake don't suggest they might survive a spin at low altitude.......Yikers!!!!! Also, think about this.....one wing develops full lift(VG's) on takeoff before the other is even flying.....nice roll to the un-VG'd wing......maybe even all the way inverted if your not reacting fast enough. Or how about the unequal lift causing the need for constant roll correction .....better get to the gym and work those biceps. NO nothing good can come of VG's on one wing only!

I was wondering how they are made, how they are attatched to the Polyfiber? and where on the wing chord are they located for optimal effect? Also interested if anyone has done an oil flow test on the wing to get a better idea of what the air is doing normally and around the VG's. It would certainly confirm where to place the VG's if nothing else. I suspect nobody has volunteered to get their wing oily yet....I don't blame them. I also know of some other type of Turbulators that can substancially improve wing performance, more aimed at gliders, however may work on a Kolb wing as well. -------- Ray Kolb UltraStar (Cuyuna UL-202) Moni MotorGlider Schreder HP-11 Glider Riverside County, CA Do Not Archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=165254#165254 ________________________________ Message 17 ____________________________________ Time: 02:17:13 PM PST US From: Bob Noyer Subject: Re: Kolb-List: Re: Vg's Ray, ck Archives. ________________________________ Message 18 ____________________________________ Time: 02:35:58 PM PST US From: Russ Kinne Subject: Re: Kolb-List: lurkers and learners GOOD ON YOU, BILL/OLD FS!!

Not saying this is the best, but works great for me. My approach was similar the factory method with a few tweaks recommended by John H and his brother Jim. Used existing gear sockets and did not make mods to move forward like on Miss P'fer. As John H said and recommended: 1.375 x .120 wall 4130 All welding, fitting, aligning, drilling done prior to heat treating to RC48. Really hard to drill once heat treated. They heat treater will tell you that the tubes will distort some. Not enough to matter in my opinion. My axle sockets are 1.00 x .120 wall for the bigger, better 3/4" Matco W62 axles with tapered bearings. These axles are heavy duty and have a lot more brake pad surface area. Braking is much improved. I know some guys that can land with their wheels locked on a grass strip to make sure they win a shortest landing contest with these brakes. [Wink] The other thing is 800-6.0 tires. Between the Heat treated still legs and the larger tires, the cushion and energy absorbed on landing is great. I really had trouble knowing when I was down and rolling when I first used the new setup. You have to experiment with the air pressure a bit. Too much air pressure will throw you back into the air. John H. and Brother Jim recommended I put in 7 degrees of positive camber on the axles. If you notice a few of the folks with the factory legs have the Kolb gear squat after a few tough landings. This was true for the original factory steel gear. Maybe they have improved this with a little positive camber now. I put in the 7 degrees + camber and thought I would field adjust a lot of that out with some hard landings and end up close to zero camber. Hasn't happened yet. Somewhere between 5 and 7 degrees would be right. I have a CUB like pigeon toe look gear unloaded and airborne. Hope I got this positive/negative camber thing right. see picture Back in 2006 when I did this: 4130 was about $60 Matco W62 axles - ~$445.00 Heat treating - $110.00 800 - 6.0 Tires from Dresser $164.00 E-mail direct if you want to discuss more and I can be of any help. John H and his Brother Jim were a big help to me. don't want to take credit due them. I'm sure I'm an "idiot" for the way I did it. But I like it a lot. And I have a little fear when I go as slow as I can.

Too much air pressure >will throw you back into the air... This reminds me of a totally different question I've been meaning to ask. My UltraStar, of course, has absolutely no flex to the gear legs, so the tires are it. I have Freebird wheels and brakes, with tubeless wheelbarrow tires. With fairly low air pressure I get adequate cushioning, but the other day I was turning tight on the runway with the help of brakes, and apparently twisted the tire right on the wheel enough to make it go completely flat. The tire never came completely off the wheel, so I was able to reinflate it with no problem. Is this a common problem? How do you deal with this... should I be using tubes? -Dana -- Diplomacy: Saying "nice doggy" until you find a rock. ________________________________ Message 32 ____________________________________ Time: 06:54:01 PM PST US From: "John Hauck" Subject: Re: Kolb-List: Tires, was: Re: Building your own gear legs How do > you deal with this... should I be using tubes? > > -Dana Dana: That is what I would do.

Tubes help keep it from coming off the bead but, then sometimes from using low psi you will spin the tire on the rim tearing up the stem of the tube. You can usually fix that by drilling 2 small holes in the bead of the rim and put small screws into the bead of the tire to keep them from spinning under heavy breaking but, from then on you will not be able to go tubeless.
