Drum roll please........ the much awaited MK IV manual.  Thanks to Nick L for sending me the manual to scan in.

Files are broken down into sections so they are not a giant down load for those that dont have high speed internet.

For the record, the build manual is for my Avid Flyer MKIV serial number 1174D, and is of about a 1994 vintage.

Does anyone have instructions for applying the fiberglass leading edge cover?  Avid Mk IV Manual only  shows aluminum which is one piece, unless I missed some revision - the fiberglass is supplied in 4 foot sections.  EDMO

Ed - perhaps you can find some help from these photos of the Kitfox 7's optional 'Laker Leading Edge'. I would also note that this install chose not to use Hysol.

Here is where it gets interesting. This is likely the first installation of a LLE using 3M's 850 adhesive instead of the usual HySol epoxy bond. This is the same product I believe that Kitfox uses on the flaperons now to bond the trailing edges with good success and is used extensively in the auto industry and hundreds of other manufacturing processes for strong secure bonds. It stays slightly flexible when cured unlike HySol but retains a very strong bond. In the first photo you see Bill showing us the proper application and locations on the wing for best strength on the first of four sections of LLE. I applied the other 3 sections duplicating what was demonstrated on the first section. It went very quickly compared to using HySol. Likely less weight also for a superior bond.

Thanks Doug,  This is very informative - didn't know they wrapped the front spar with it.  And I just bought another 2 cans of 9460!  But I still need some for the intercostels on the tail.  I may still use 9460, but will check out the other glue mentioned.  My flaps wont be bending like a 13 foot wing, since they are only 6 feet long and 15" chord. 

Scalloped edges front and rear were another surprise to me, although mine wont need that.  I was thinking about some riveting to front and trailing edge for my flaps too - guess overkill never hurts - just more time and money spent.  Of course the Kitfox FG on wings will be overlaid with fabric where mine will just be painted.   I could overlay mine with fabric if someone can give me a good reason.  ???  Good Post.   EDMO

I was going to bring my manual home today but forgot in the rush to get home and finish my hurricane prep. If you still need the avid one I'll be going out to inspect my hanger after the hurricane and will grab it then .

Thanks, but I guess I can figure out how to stick some FG to wood and metal.  Like Jim said, the MkIV HH ribs are set on one foot centers, so there should be no spicing info in the manual. 

I have been looking for the 3M 850 adhesive in Doug's post on their site and cant find it - I never could find anything on 3M site - Maybe it is me - I looked for the green and also clear glue like Stewarts and Oratex used for about a month and finally gave up - Maybe I am getting too old?   EDMO

Ed- I think the guy may be confused which 3M adhesive it was. Look up 3M 550 Fast Cure Polyurethane Adhesive Sealant
