    Subject: Wing covering...scallop or no scallop?
    From: Lynn Matteson <lynnmatt@jps.net>
    --> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net> I'm in the process of covering a wing, and have some concerns about whether to follow the Poly-fiber manual and video, or the Skystar manual (old and newer version). (I have covered the vertical fin and rudder so far with no problems, and have done 8 foot models with Poly-fiber, so I'm up to speed with the process) I'm pondering the SS suggestion of scalloping the lower fabric/leading edge attachment point of the Poly-fiber material. The newer manual (SS) tells you to follow the Poly-fiber manual, but SS "suggests" that you scallop the leading edge material so that it can be wrapped around the upper part of the front spar. I cannot figure why this would be necessary. It makes for a lot more work, and the advantages are questionable, to me anyway. If the lines are snapped and fabric is cut per Poly-fiber, and there is a 2" fabric-to-fabric overlap, and the seam is covered with, in my case, a 6" finishing tape, where is the need for this scalloping? Also, they (SS) show and tell you to Poly-tak each rib capstrip during the covering process, and this is not done in either the P-F manual or the P-F video. The concave-bottom wing instructions warn against Poly-takking the top surface of the capstrips, and a phone call to P-F maintained this procedure...that is, Poly-tak on the lower capstrips only (for initial bonding prior to rib lacing), and letting the upper surface fabric "float". No techies were available at SS yesterday to answer these questions. Any input would be appreciated...in the meantime, I'll search the archives...thanks. Lynn

    Subject: Wing covering...scallop or no scallop?
    --> Kitfox-List message posted by: "Flier" <flier@sbcglobal.net> Lynn, I think you're talking about wrapping the lower fabric all the way around the front spar to gain the 3/4 attachment. To do this you would have to cut the material to lay in between the top ribs and false ribs. If I recall I did this. The thing it will do for you is you won't leave a line down the length of the leading edge that shows through to the top fabric. Anytime you overlap the fabric there will be a line left showing. Scalloping like that leaves only trim lines across the ribs visible once the top fabric overlaps. Looks nicer. On a large area like that the 3/4 or better wrap is not as much of a safety issue but clearly anytime you have more contact area it's a better thing. On the top ribs, coat them with polytak and let it dry. Apply the top fabric and shrink, then come back across the capstrips with heavily thinned polytak or just MEK to activate the polytak underneath the fabric and secure it to the capstrip. On the bottom fabric, make sure you get really good adhesion when you first apply the fabric else it can pull away from the camber.

    --> Kitfox-List message posted by: "Flier" <flier@sbcglobal.net> You're right Howard. Good point. I left that out in my other post. Glueing the scallops allows you to pass the iron over the leading edge and the fabric pulls up tight. That's a tough place to get all the bubbles out anyway if you glue on the leading edge...

    --> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net> Ok, I see what the reasoning is now for the scalloping...not so much for a strength issue, but for appearances. Now on the polytak on the top ribs issue, PF clearly states "if you plan to rib lace....DO NOT cement the fabric to the top surface ribs"...this is on page 97 of the PF manual, Revision 20, in the appendix on concave-bottom wings. In my phone conversation with PF yesterday, the tech also reiterated this point. They want the fabric to float during the rib lacing process. Ted, did you rib lace? I can see the polytak being applied to the top of the ribs if rib lacing is not done, but following PF's advice to NOT polytak the upper-rib capstrips seems right, as they are the people who should know. I'm not doubting your advice, just trying to clarify.

    Subject: Wing covering...scallop or no scallop?
    --> Kitfox-List message posted by: "Randy Daughenbaugh" <rjdaugh@rapidnet.com> As Ted said, I am a real advocate of putting two coats of polytak on the top of the ribs and then let it dry. After gluing the clothe to the end ribs and leading and trailing edge, do a preliminary heat shrink, then just brush some MEK on the top of the ribs and the polytak will soak right up into the clothe and it is all very quickly glued in the right spot. Then finish shrinking. This works on the concave areas too if the preliminary heat shrink is not too tight. Just lay a small open end wrench between the ribs to pull the fabric down to the rib surface and then hit it with the MEK.

    Subject: Weight and balance - Jabiru/KF3
    --> Kitfox-List message posted by: Michel Verheughe <michel@online.no> Hello guys, Today, I did the W&B with the new Jabiru 2200 on my Kitfox 3. The new cowling was in place, although it is not painted yet. Oil was in the engine but no fuel. The good news is that the plane (previously with a Rotax 582) weight only two kilos more than before. The bad news is that the weight is now more forward. My tail used to be 20 Kg, it is now 13 kg. That brings the CoG 26 cm from the leading edge, where it should be rather 36 cm. That brings me forward of the allowed limit. :-( To change that, I'll need, at least, 4 kg in the tail. Man, I'd hate to fly with a lead weight in the tail! What went wrong? Well, nothing, but the Jab is more forward than the 582. About 6 cm. Any idea how I can get my CoG in the right place without moving the battery which is now on the cockpit side of the firewall? Cheers, Michel

    --> Kitfox-List message posted by: "Don Pearsall" <donpearsall@comcast.net> Michel, Swinging the wings forward will give you more aft weight. I realize that that is not practical since the spars are already drilled, though. Also moving your seat back will do it. How about putting the ELT way in back? A heavier tail wheel? But most people end up putting ballast in back (dead weight) or the battery (live weight).

    Subject: Re: Florida Flying
    --> Kitfox-List message posted by: Mdkitfox@aol.com Kurt, I looked at about a half a dozen places in Florida. I've had of the snow, cold, and ice. Since I fly for Delta Connection Carrier, ASA, (I will have to retire in about 18 months.) I needed a place near the same airports. Looked all over and came to the conclusion that Spruce Creek was about as good as it gets. Centrally located and affordable, but no float plane capability. Looked at Love's landing, Leeward and a few others. They all offered a runway, but not much else, and they were in the same price range as Spruce Creek. I ended up buying a new home at Spruce Creek. It's not a taxiway home, but it is on the golf course with a garage big enough for a folded wing Fox, and just 4 homes from a taxiway. It's currently being rented out until I can move down there. Be glad to talk to you if you want 301-502-8029 (cell) 301-805-9584 (home) By the way, after I move down there, the party's at my place, all Foxes invited!

    --> Kitfox-List message posted by: "Steve Cooper" <spdrflyr@earthlink.net> Michel...I moved the battery behind the seat and used #4 welding cable to hook it up. The weight of the battery and the cables should get you close to where you want to be...the middle of the CG range I would think...although I'm slightly forward of middle CG.

    Subject: Wing covering...scallop or no scallop?
    --> Kitfox-List message posted by: "Flier" <flier@sbcglobal.net> I did lace. You don't polytak the fabric to the top ribs before shrinking. If you've applied a coat of polytak to the top capstrip and let it DRY, then installed and shrunk the fabric (it's loose over all the ribs), when you apply the brushcoat of polybrush, the fabric is going to stick to the ribs anyway as the wet polybrush will cause the underlying polytak to grab. You don't apply wet polytak when applying the fabric to the top though (which is what you havta do for the bottom due to the camber). The capstrips on the Kitfox are wide and sufficient to hold the fabric with adhesive only. I just like the looks of ribstitching and it does offer greater insurance. Once the fabric is shrunk and the Polybrush applied, the fabric is basically adhered to the capstrips anyway even without polytak being brushed and dried first. Actually, I adjusted my the lay of my false ribs through the fabric after it was shrunk then the polybrush holds'em nice and tight...

    --> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net> AHA! Now it get it...duh. In re-reading the concave-bottom wing section of the PF manual, where it says "brush the lower capstrips ONLY..." and later "...DO NOT cement the fabric to the top surface ribs", they could have been a little more clear in their explanation by adding something like: "these top surface ribs will become cemented down by the later application of polybrush." I need these little assurances along the way...thanks, Ted, for the explanation. I kept reading these "do not's" and "only's" and so on, and was getting pretty paranoid about the whole thing.

    Subject: Weight and Balance
    --> Kitfox-List message posted by: Jim Gilliatt <jim.gilliatt@att.net> Michel, I have a friend with a Kitfox III and a Jabiru 2200. He hasn't flown it yet, but his weight and balance came out with figures showing a CG at 11.5 inches from the leading edge. It was done by putting a 26 pound batter behind the seat. If you want to talk to him for more details, he is at foxtrat3859@aol.com. Jim Gilliatt

    From: Lynn Matteson <lynnmatt@jps.net>
    --> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net> One more thing, Ted...the Poly-fiber rep in my area told me that when rib lacing the Kitfox, I only needed to lace from the trailing edge forward to where the false ribs end, Further forward than that, the surfaces of the top and bottom of the wing are under pressure, and lacing there is not required, and in fact, undesirable because the slope of the surfaces would cause the lacing to want to "slide the fabric down the curve of the rib." This sounds like it makes sense...more for the pressure theory than the sliding fabric theory...to me. Thoughts?

    Subject: Wing covering...scallop or no scallop?
    --> Kitfox-List message posted by: "Flier" <flier@sbcglobal.net> Hey Lynn, if the Polyfiber guy said so then I sure ain't in a position to argue! : ) I evenly spaced mine all the way if I remember from about 3 or 4 inches aft of the front spar. Has worked fine for me. I used regular round lacing but ended up using the flat on the Nieuport and I think I'd have used it on the Kitfox if I'd had it. I thought it might be a pain to work with but it's not at all. Enjoy. Fabric is when the thing really starts looking like a plane!

If it is, a pilot in the seat will move the CG back a little. Try to think of moving some existing weight...preferably from forward of the CG limits...back a little before adding weight to the tail. Add weight in the tail as a last resort only! Tom Jones
