Previously I had found the pre drilled aft bottom skin had the tie down hole in the wrong place.  



Today, I find the leading edge skins are not only misdrilled for the outboard nose rib but the are also 10 mm too short at the wing tip and 5mm too short on the inboard side.



Called Zenith and Caleab confirmed they have a bad batch of skins.



I picked up my kit at the May 11, 07 rudder class.



Any one else having any problems with the skins?

My wing kit shipped on 2/2/07.



Pre-drilled holes were fine on mine (at least for the right wing - will know about the left wing in a coulpe weeks...)



My skins didn't have the tie down holes drilled.  They did have all the pilot holes for the ribs drilled, as well as the access panel holes for the aileron belcrank & fuel sender areas.  They were also marked (but not cut) for where to cut the landing light (which was fine by me since I'm not going with a wing mounted landing light).



Hope this data point helps somebody.

Floyd,



I picked up my wing kit about a week before you and feel I got the same skins. I talked with Caleb last week about swapping rear ribs #9 to put the web on the side in agreement with with mis-cut tiedown slot. They were aware of the error and have since corrected .. unlucky us. I did this rib swap last weekend and have also noticed that the skins not lining up at the i/b and o/b ends like you. I mentioned this and he said the difference can be made up in trimming for the wing tips and when mounting the root to the fuselage.  I suppose when I get there seeing will be believing, but was not happy with the overall quality of these CNC cut skins. On the nose rib, I had to moved it inboard of spar L attachment and trimmed the aft edge to fit. This made the predrilled holes work, but not perfect. Did he offer to swap your bad skins for good ones?

Yes

 I to had a Late May kit and did not find out till the other day that my Bottom Fuse rear skin predrilled holes were wrong. Around the rear access door cross stringer it should have been pitch 40 but mine were all a very even pitch 28.. Yep phoned up and now I have twice as many rivests holding that section together.. 



Yep they had problems setting upo the new machine that they missed. the rest were all OK and now the people behind us are in a better off position..

I swapped the nose rib with the other wing and it lined up OK.



As the first they really knew of the problem was when I called, no they did 

not offer to send more skins.



Between my call to him and his return call, he pulled all the skins from the 

shelf so no more would be shipped.



I believe that the fiberglass wing tips do have enough flange to cover the 

problem and probably the molding will cover the root.



Hopefully I will be able to verify this latter this week.

Just a note of frustration for all you guys who are suffering from 

errors in the newly "Engineered" pre-drilled skins, etc.  This all 

makes me think that my next CH601XL will be scratch built.

When I hear complaints like these, I realize how fortunate we all are.  What I'm *not* hearing are complaints like, "massive structural failure" or "unstable in all axes".



Any aircraft design still in production is in a state of flux.  It can be the newest whiz-bang design with a single example flying or a spam can using 1940's technology.  Any design is going to evolve and usually for the better.  (My apologies to those in Kansas for using the "E" word.)

The down side of this is that sometimes T's will not be crossed and I's will not be dotted.  



That much, I can live with.  More importantly, I can fly with it as well.



Regards,

Kevin Kinney

Question for you guys with the problem skins:  Did ZAC trim the wing tips and wing root as well?

Hi Tim,



Yep, they trimmed them as part of their CNC milling process.
