I "think" there was a situation where he straightened a bent gear for a customer as no cost and it was the customers fault not the gear. Look at it this way, the Grove gear might be the only item on the plane with a life time warranty. Check with Robbie on this.

I have flown a model 4 w/ the gear and found it to handle very well. Having said that;I have flown at least a dozen different taildraggers over the last 35 yrs ,some of them for a lot of hrs,and have never flown a plane that handles as well on the ground as my 4-1200 Soob Kitfox,w/ standard "out of the box" gear. If one is having trouble w/ the standard gear,it might be worth checking the toe-in ,toe-out of the gear.Mine is pretty straight and will track straight down the runway w/ a very minimal input from the rudder. If you have a problem w/ weight the solid gear are heavier,so take that into account. I weight quite a bit more than the "average"170# pilot. My wife and I put our bird pretty close to gross,so I don't need more weight. I have flown the standard gear for over 400 hrs now and am perfectly satisfied w/ it. Not trying to rain on anyone's parade.Just stating facts as I see them. Again ,I think the Grove gear is a fine product. If you think that is what you prefer,you should be flying it.

I want to add them to our plane but have not done so yet for reasons I will explain below. For me, the primary reason for owning a Kitfox is for "off airport" ops and general short field stuff. So anything I do to the airplane should allow me land and takeoff shorter, get to the short field faster, haul more stuff to the short field or do these things with less risk of damage or injury. Having a lower stall speed would in theory allow you to land and takeoff shorter. But there may be some practical limitations imposed by your airplane. So consider the following: During your flight testing, have you done many short field, 3 point landings? If so, have you noticed that you can land the plane "tailwheel first" with ease without the VG's installed? If you are able to do so, consider what would happen if VG's allowed the plane to stall at a higher angle of attack. On our Kitfox, when I do a full stall, 3 point landing, the tailwheel touches down first while the mains are still at least 1 foot above the ground (maybe more). The plane is configured with 600 x 6 tires and a Maule 8" pneumatic tailwheel. If I add VG's and increase the angle of attack at the stall, with or without a change to the IAS, the mains will likely be 18"-24" above ground at the stall. And this is doing full stall landings with power at idle, imagine what happens when I do it with power! This is one of the reasons that Alaska bush pilots install extended landing gear. It allows the plane to stall in a "3 point" attitude without the tailwheel making such violent contact with ground. Also consider that these bush pilots don't even consider it a short field landing unless it's done with lots of power, with the plane landing at a very high angle. As you can imagine, if you are landing on the tailwheel first, it won't be long before damage is done to the tail end of the plane. I plan to change to 8.50 X 6 tires, and install the small homebuilders special tailwheel. This will give the tailwheel a little more room. But I suspect that I will still be able to land tailwheel first. I have talked with numerous people about this issue, and while the kitfox is a great airplane, there are some design flaws that keep it from achieving it's full potential as a bush plane. After all, the wing on the model 5 was really designed for the model 4 at a gross weight of 1050 lbs. We are asking it to do bush work at 1550 lbs, that is 57% more weight than the plane for which the wing was designed!!!!!! Ideally, for bush flying, the model 5 needs a higher lift wing, the wing needs to be set at a higher angle relative to the fuselage and it could use a little longer landing gear (among other things). Despite these shortcomings, I still love our kitfox and will likely add Vs. for the safety factor. If they soften the stall and prevent it from dropping a wing in a deep stall, then that would be worthwhile because I so often fly the plane right on the edge of stall. Especially when doing short field ops.

But I am not Kurt, a man who has a lifetime as a professional pilot and who is now using all his knowledge to break down his new baby into accurate figures. My quest was much simpler, I simply wanted to know if my relatively high stall speed was due to a misreading from maybe a slightly bent pitot tube. I measured the speed when landing because I was sure that at the windsock altitude, the wind was nil. I checked the indicated speed vs. the GPS ground speed when flaring, i.e. high angle of incidence. That's all. As soon as the plane stalled and the wheels were on the ground, any reading would had been misleading. In any case, I am aware that the most important is to know the relative stall speed, i.e. what is indicated on my instrument, however it is calibrated. The absolute speed, or true airspeed, is only a matter of secondary interest. As it turned out, the GPS reading was pretty close to the indicated one and I don't need to investigate any further. Right now, I am enjoying very much flying with my son as we train navigation and radio communication. When we are done with that, we will maybe train a bit with different flaps setting, something we haven't done yet. BTW, this last week-end has been gorgeous in south Norway. A high pressure gave us fantastic autumnal conditions, no wind, excellent visibility, great nature in autumn colours, smooth air ... and we went flying both days, in formation with a Rans. Life can't be better!

I did give it some thought and my manual - March 03 - also didn't mention the adhesive. I recall a couple of posts describing a looseness in the riveted connection after time. Maybe it was reports like this to the factory that prompted a change in the assembly. The only disadvantage in using the adhesive might be if disassembly is desired at a future date. I would think that heating the adhesive might soften it enough that it would come apart after drilling out the rivets.

It is 1-1/4" wide by .291 thick heat treated 5140 steel. This is to replace the spring on my KF III and it looks like I won't have to dig out that bolt that is bonded to the airframe. Woo-Hoo!

Also note: please ask him to make sure the rear hole (larger hole in the end that is square) is closely centered in the spring. Mine is not but is OK since I have enlarge the hole in the Matco tail wheel bracket to match. If you are keeping that !#%@#$ Maul tail wheel that's another story. Anyone wants to buy my old tail wheel let me know. Best part: The turnaround time to cut, machine, bend, *and* heat-treat was only two days!

In the Aug. '03 revision, they say to use structural adhesive...in the Mar '03, per Lowell, they don't mention the adhesive, and they don't mention it in the original Sept. '92 version manual that came with my kit. I was consulting the later version of the manual to see what changes have been brought about, and maybe that's getting me in trouble. My flaperon end ribs are now riveted in, as are the horns. I used no adhesive, per the original manual. I've been contemplating drilling out all 17 rivets...10 for the end ribs, and the 4 for the flap horn, and the 3 for the retainer ring....and putting it all back together using structural adhesive for the end rib/flaperon connection, but this seems like destructive work. Maybe I can just drill out the 10 rivets that hold the rib to the flap, slide some structural adhesive in the gap and close it up...yeah, that seems like a good plan.

Let me know if what type of paint you have on the airplane now. If you don't know the name of the paint or the type of paint (lacquer type or enamel type) Try a little MEK on a dark rag like a scrap of black T shirt. Wipe a little spot (not too visible) and if it softens the paint and you get white paint on the rag then it is Lacquer type. (could be Polytone) if it doesn't soften and the rag does not get white then it is enamel type. (could be Aerothane). Whether lacquer or enamel type, both will be influenced by acid rain. Especially if the pigment is not well protected with clear. If the paint system is of the enamel type you could sand it down with P600 to P800 grit wet and spray a coat and a half of enamel type clear. This will greatly protect against acid rain. I work for a paint company, Akzo Nobel. I sprayed my Classic IV with a product called Sikkens Autocryl and after wet sanding I sprayed a product named Autoclear III. Make sure you use Elast-O-Actif, this is an elastofier that does not leach out of the paint. I added 50% of the flex additive to the paint before adding hardener and reducers. If the paint that you have on the airplane is of the lacquer type (Polytone) do not spray an enamel clear coat. It will probable peel off. Note: before sanding. Wash the surface down with a grey scotch brite pad and plenty of baking soda. This will neutralize any acidity that is impregnated the surface (usually causing craters). Greetings.

In the true sense of the word "enamel".Is a coating that is chemically active during it's drying process. When dry, a true enamel will not dissolve to it's own solvent or a more aggressive solvent, it may wrinkle and disintegrate under harsh solvents (if it is of a week structure) but it will not become a liquid again. Aerothane (by Poly Fiber Corp.) Is as you say, a two component polyurethane. And must have a hardener to chemically cross link and as such is a very resilient paint film (a true enamel that will not wrinkle unless subjected to very harsh chemicals like paint stripper) On the other hand, Poly Tone is a one component (no hardener) air drying, physical drying material. No chemical reaction is taking place. Nothing wrong with this stuff, traditionalist love the sheen and finish. I saw a yellow Cub that was just sprayed (Don's Dream Machines in Griffin GA) It was a work of art, a finish that only this product can provide.. one word 'silky" Poly Tone can be "rejuvenated" and easily repaired. That is because it will soften and will become liquid again if enough solvent is introduced into the existing paint. This temporary softening is a bonus for and during the repair process. Down side to Poly Tone. Not that wet look and not as resistant to the environment as Aerothane. Polytone usually sprayed on fabric airplanes and usually kept in hangers. You have probably noticed the ones at the local airport that are left outside...shame. ________________________________ Message 20 ____________________________________ Time: 05:22:36 PM PST US From: Ceashman@aol.com Subject: Re: Kitfox-List: Paint - Need to clear coat --> Kitfox-List message posted by: Ceashman@aol.com --> Kitfox-List message posted by: jareds -->I used a poly system with polytone. -->If i read your email correctly putting clear over poly tone might flake -->but if i put a eurothane on top of what i have and then a clear would -->that work for a while? Hi Jared. I am not saying you cannot use clear polyurethane enamel over the top of Poly Tone. You can risk the clear peeling off but there are some things you can do to prevent or greatly reduce the risk. For example, I used the Poly Fiber Polybrush and Poly Spray. Both of which are air drying materials (can be dissolved with thinner). But after the silver coat, Poly Spray (that you must apply to protect from UV light, and I think to be legal) I left the silver for a good week before sanding and applying a polyurethane sealer on top. No adhesion problems. So' If what you are saying is that you must re color because of staining. I would apply one coat of color, Use Aerothane of the same white color, do not change the color you may have coverage problems. And then use a polyurethane clear coat. Because the existing finish is relatively old and the color is the same you do not risk the solvent penetrating into the existing finish. This is the main contributor to the clear coat peeling problem. Hope this helps. One other thing to consider. Why not sand your airplane and re apply Poly Tone. This is the finish you were looking for originally (it is cool!) Cheers Eric. ________________________________ Message 21 ____________________________________ Time: 06:39:12 PM PST US From: "Larry Huntley" Subject: Re: Kitfox-List: Paint - Need to clear coat --> Kitfox-List message posted by: "Larry Huntley" FWIIW, Why not just spray on a coat of same color PolyFiber Aerothane and leave it at that? That is what I did after my Polytone stained from "bugjuice". Aerothane is shiny and doesn't need clearcoat.That was a year ago and it looks like it did when I put it on.

There is a more superior method of securing the handle in place that can be easily incorporated.

I did clear coat Aerothane over my PolyTone on the fuel tanks and first rib bay, but I still get gas stains. Too soon to tell about the adheasion, but PolyFiber says they are compatable since you Aerothane over PolySpray anyway. They warn that moisture will get under the clear coat and grow fungus on the PolyTone in humid climates. When I lived in L.A., I had an entire lawn chair/table set disintegrate in a single year due to the pollution. The fabric umbrella turned brown and fell apart first. I am not sure wax would help that much more in that kind of pollution.

I also have the grove gear with 6x6 tires and the Maule TW. 6x8 tires are standing by. The early Grove gear was much taller. Melnik's plane had it at first and I think Tom Anderson's too. It probably was a better match for short fields, but you'd have to ask them. I have not gained the skill level yet to do good short field landings power off, let alone power on. I enjoy slow flight at altitude, but have not risked it yet down low. It is an old helo driver flaw of mine. Fear of fixed wings slow and low. Something I have to train myself to overcome. I do 3 point landings and note that it is often not quite stalled yet, so getting a bounce is still easy. Planting the tail sometimes works, but just a few knots faster or a bump in the grass and I'm up again. I have been cheating lately by using 1/2 flaps and dumping them on landing. More by luck than intent, I find that landing tailwheel first power off doesn't drop me on the mains that badly. Power on may be a different story. I got a lot of training to do before I get that good though. I would like to have the VG speed reduction to use, if needed, so I'll test them some more later. Kurt S.
