I think you will be OK with the match, however if you have a 2:5:1 you may need to find some 3:23:1 or lower gears for a non-turbo application. I ran 3X72 warp drives on the NSI hub and 3:34:1 was just about right for the turbo. Maybe the 68s will make a big difference, not sure. Gear are tough to come by as the redrives are not being built. Check with Engerfeller and see if he got all of NSIs old stock. I have an NSI CAP hub assembly for sale should you or someone else need a replacement or spare. -----Original Message----- [mailto:owner-kitfox-list-server@matronics.com] On Behalf Of QSS Sent: Sunday, June 25, 2006 12:19 AM Hi Guy, can anyone tell me if a 68inch Warp Drive 3 blade prop will match up with an NSI gear box.

Subject: Kitfox-List: kitfox spar damage I have two damaged spars which I'm still working on removing. The previous owner started repairs and the workmanship is good, I'm just doubtful of the whole concept. The rear spar in one wing is cut and spliced just a bit before the insert stops between ribs 7 and 8. The front spars appears fine. I've attached a photo of the splice. It has a sleeve over it and I think it has an extension of the insert inside. It looks like they riveted a plate on the insert web and used part of another insert as an extension. No photos of that, it's hard enough to decide what I'm looking at down there. Does anyone think this would work? The second spar is dented at the jury strut attach point. There's a slight bend to the spar starting at this dent, I've not yet measured it, it looks like about 1/2" bow. I expect the only advice I will get is that it must be replaced, but I'll ask anyway. Pictures are attached I hope. ________________________________ Message 10 ____________________________________ Time: 08:51:25 AM PST US From: "Dave" Subject: Re: Kitfox-List: kitfox spar damage Dave G, Unreal is all I have to say. Splicing spars like that is very Mickey Mouse to say the least. If you have any dents in the spars and you say at the wing atach point the integrity and strength has been comprized. I would replace any spar tube that has damage as well as anything else that has been damaged. I cannot comprehend what one was thinking to make those repairs in the photos. I would suggest getting an expericend builder to look over your entire Kitfox. Dave ----- Original Message ----- From: Dave G.

Subject: Re: Kitfox-List: kitfox spar damage The original builder did an exceptional job, and flew the plane many hundreds of hours as far as I know. It was sold when he built another, The incident that damaged the wings occured for the third owner. I've looked over the whole aircraft and the wings appear to be the major damage. There was slight damage to the tailpost but it's been repaired well. Nothing else is dented, wrinkled, cracked or bent as far as I've been able to find. The only irritation is the aerothane paint job, it's hard to sand off for patching small spots. I'll be using polytone for the wings. ----- Original Message ----- From: Dave To: kitfox-list@matronics.com Sent: Sunday, June 25, 2006 12:49 PM Subject: Re: Kitfox-List: kitfox spar damage I would suggest getting an expericend builder to look over your entire Kitfox.

Of course Kreem is still available, I'm told it was used at least for a while by the factory. I found this product: http://www.caswellplating.com/aids/epoxygas.htm Which appears interesting.

But what I see in the photo is absolutely unacceptable in any form. There is NO way to save that spar. Sleeving with over sized or undersized tube works but a split tube scabbed over a break is not acceptable by any either the Hang gliding industry or the Aviation industry as detailed in publication 43.13-1A/2A. Any permanent bend in the spar is reason for rejection. No need to quantify it. It is evidence of failure. Jim Shumaker "Dave G." wrote: I have two damaged spars which I'm still working on removing.

The rear spar of a Kitfox carries a larger load than the front spar. Based on the photos, I don't see how the damaged rear spar in the photo could possibly carry the design loads. I don't see how a person could even guess at what load it COULD carry - or for how long. FYI - I threw away two brand new spars supplied by Skyclinker because of dents and radial scratches in the surface - also had a DC-9 mechanic (familiar with lots of aluminum) look at them before I decided. Your comments; "I'm just doubtful of the whole concept." & "...it's hard enough to decide what I'm looking at down there..." tells me you know the answer. I would suggest that you go with your better judgment - you are looking at the parts more directly than we ever can through a photo. Anytime a person is dealing with a damaged aircraft, A person will only know the entire aircraft is safe if a complete disassembly is done, every part of the aircraft is inspected, assesssed, and either A) re-used if within acceptable service limits; or B) replaced if: 1) not within acceptable service limits; or, 2) replaced if not in original condition and the service limits are unknown. There are probably three real good ways to handle this. 1) Stick with the specifications of the kit manufacture for the model you have; 2) Have a competent Airframe mechanic look it over; 3) Make sure the repair or replacement is complete and in reasonable agreement with the procedures laid out in the FAA's Advisor Circular on acceptable repairs. My comments may be a bit of overkill for some; however, there has not been a structural failure of a wing spar on a kitfox............yet..................

You say the workmanship is good but I guess you forgot to include a picture of that part because what I see in these pictures is an absolute disaster. That split tube repair wouldn't be acceptable on a farm tractor. For that doubler repair to be even remotely effective it would require many more high quality fasteners properly placed and spaced throughout the patch, not just a few pop rivets randomly placed here and there. All that is beside the point since this kind of repair has no business on a tubular wing spar. Whoever flew this airplane after that repair is extremely lucky that he has not reached a G load that would have shown him , in a very unpleasant way, what a poor repair this is.

No!!! > The second spar is dented at the jury strut attach > point. There's a slight bend to the spar.... SkyStar didnt even allow scratches on the spar, and with good reason. The spars flex like bending coat hangars. If undamaged, they will flex a long time without breaking. But if damaged, even scratched, they will fail much sooner, like a coat hangar would. If you took an empty can and stacked bricks on it, the can would hold up quite a few without crunching. But if you cut open one side, only a few bricks would flatten it. Same with that spliced spar. A very weak fix. It is doomed!

Subject: Re: Kitfox-List: kitfox spar damage I think you misunderstand, the aircraft was never flown this way. My comment that the workmanship was good on this repair reflects the fact that there are no spaces, chips or gaps. All the rivets reflect exactly the specified pattern for the original construction, and all edges are radiused and relieved. All the replaced ribs are in the correct position, vertical, and the spar is straight as a die. So the work is fine, it's the concept that's flawed. I was never in doubt that the spliced spar required replacement. I was never in a great deal of doubt about the dented one, but the damage is not severe and there is/was a shred of doubt about that one. ----- Original Message ----- From: Eric To: kitfox-list@matronics.com Sent: Sunday, June 25, 2006 3:22 PM Subject: Re: Kitfox-List: kitfox spar damage Dave, ditto to all the other comments about that spar repair.

At approx. 175# you can't match that HP/weight ratio with any other auto conversion engine. Plus there are no gear boxes to mess with and the parts and technical help is readily available. This is a very simple engine that looks to be nearly bullet proof. Sonex uses their own version of the VW in their planes and from what I hear the customers are very happy. I think it also depends on what you expect from your plane. This is just my humble opinion based on my research. Check the Great Plains website if you desire more info..

You know, tear it down is sections and basically slip them right over the new spars. drill out all the rivets match them in place to the new spars and rivet. Should be pretty easy. You will need to figure what your going to do with the center thing amagigies in the spars at mid way. You could remove the old ones and turn them around and reinstall in the new spars or just buy new ones. Other than that, the wing is pretty simple to build. Get the latest on the plans for building the wings. I would say the only things you need to buy are the spars, rivets, and maybe the inserts, and some hysol. build some saw horses for construction. -------- kitfoxmike kitfox4 1200 912ul speedster http://www.frappr.com/kitfoxmike Read this topic online here: http://forums.matronics.com/viewtopic.php?p=43015#43015 ________________________________ Message 39 ____________________________________ Time: 07:20:31 PM PST US From: "Lowell Fitt" Subject: Re: Kitfox-List: The "Claw" tie down --> Kitfox-List message posted by: "Lowell Fitt" Thanks for the post, David.

MessageGraeme: I know nothing about the model number. My plane has a 70 inch Ward Drive Prop which has been shortened about 1/2" because of a ground-strike I was careless enough to make. I would first quote Tony Bingelis, the guru who has written several books on experimental building, when he says "Use as long a prop as you can for as long as you can". Having said that, you can always put enough pirch into the prop to keep the engine from over-revving. I cannot say what effect that would have on your climb rate or your cruise speed, however. It goes without saying that anything you gain on climb, you lose on cruise, and vice-versa. I wish I could tell you more, but this is the sum total of my knowledge about props.

Hi Guy, can anyone tell me if a 68inch Warp Drive 3 blade prop will match up with an NSI gear box. Im not sure about the gear ratio of the NSI but I have been told they are 2.5 to 1 for the EA81 engine. I was going to purchase a Bolly carbon fibre prop but the Warp Drive was offered to me for half price so its a good deal if it fits OK. If someone with could tell me which way to go it would be appreciated. Thanks in advance.

As previously posted, but I attended a Rans fly-in in Utah over the weekend at a build assist center there, and I was amazed at the number of holes drilled through the spars etc. - big holes. I sure like the kitfox - avid design.

It seemed to me that heavy enough lifting could simply lift a cone of earth out. I would likd the design better if the spikes were driven outward, increasing the circumference of the spiked area.

Before you spend a small fortune and what seems like a lifetime installing an engine in a Kitfox, spend time doing some riding. You can read all you want and all these engines are the answer to your prayers. They are heavy, they claim all kinds of neat things. If you want to find out the engines that people don't like, then look in the for sale adds, they are all over the place. Not too many Rotax powered Kitfoxes and almost all of them are powered with these. My 2 cents worth. Clint 1100 hours on 912ULS and please do not make me compare my wife to my airplane, there different. Clint Ken, What size is the VW? I am installing a Great Plains 2276 with a 1:6/1 Re drive in my series 7. This engine is said to put out 100+ HP on take off and 80+ HP continuous cruise. At approx. 175# you can't match that HP/weight ratio with any other auto conversion engine. Plus there are no gear boxes to mess with and the parts and technical help is readily available. This is a very simple engine that looks to be nearly bullet proof. Sonex uses their own version of the VW in their planes and from what I hear the customers are very happy. I think it also depends on what you expect from your plane. This is just my humble opinion based on my research. Check the Great Plains website if you desire more info..

Lowell ----- Original Message ----- Sent: Friday, June 23, 2006 12:40 AM Actually that's what I do for a living....radio control... here are a few ideas. Do not use pole motor servos, use coreless, and a quality one at that. For camera panning, I would think torque is better than speed. At least 150 inch ounces. You can now get servos well over 300 inch ounces. If you choose Hitec, buy the programmer and set dead band to min. Another thing, try not get a huge amount of sweep of camera, but set max throws on servos. This is a very common mistake. Set throws to 150% each way. This alone will make a dramatic difference. Having never done it, I still think it can work. Friction is a big no no. That will make the panning sticky.....

I vote replacing the spars. While flying my Avid a model which is the predeccessor to the Kitfox, I often tell the passenger to watch the leading edge. When I pull back on the stick it bends up, and then down on the negative g. Then they understand the concept of the wing removal tool. That spar would not tolerate the way I fly, or the unexpected turbulance often encountered.

The engineer would then have to do a load analysis on that section of wing, determine what kind of repair/material is needed and then determine if the present repair is adequate.
