Hey all just wanted an opinion.  When I opened my rudder kit and checked the integrity of everything I found only one concern.  At first I dismissed it but as I sit here waiting for my new Doubler angle I have not yet become comfortable with it.  My rudder skins came kind of wrinkled at the bottom front corner and I just wanted some opinions as to whether the integrity of the part will be compromised or if its merely aesthetic.  If it is only aesthetic will the wrinkling be removed when the skin is riveted the spar pulling it taught.  If you all think that this could be a problem I will send the photos to Zenith and see if they will replace it.  Please take a look and let me know!  Thanks again to everyone!

I think it will be removed when you rivet the skin.  Mine was damaged a lot worse and it worked out.

Its hard to tell anything from the photo. But I'd say don't worry about it.  If at the end of your build, it bothers you that much you can build another.  By that time, building a rudder will seem like child's play. The point of the rudder is for you to learn. You may make a mistake or two while assembling anyway. More likely, you will not mind a little imperfection by then. Trust me, you will have a few dents here and there--in more obvious places than the bottom of your rudder. In the big picture, It won't matter much. Of course, I'm a plans builder, so I'm a little more forgiving of the guy making my parts.  



New builders, such as yourself, tend to come into this a little anxious and trepidations. Being unfamiliar with the process, we tend to be overly concerned with getting things perfect or not making mistakes. Just Relax, and work on learning. I had to scrap my entire elevator (ribs and all)--my first scratch built part. I had to remake all the ribs and re-bend that skin that I worked so had to get perfect. I learned a lot of stuff on that second one, so I'm glad it happened. Remember this: DONT LET LITTLE MATTERS STOP YOU FROM MAKING PROGRESS! 



While you are waiting on your parts, go ahead and make a set of blocks for scratch-building parts. Just get maybe a couple of 24" pieces of oak. Rip a 10 degree angle on each side. Radius an 1/8", on one edge, each block; and 1/4" on the others. Use this to remake any small parts you mis-drill or mis-cut or whatever. Or just bend some scrap around it to get the feel; relieve stress; become one with the aluminum; etc.

Does it still need to be trimmed? If so maybe that wrinkled stuff will get snipped off anyway.



Nevermind, just looked at the picture. I see it's pre-drilled too. Even so, I don't see any damage there at all. Looks fine to me. That'll sit right down when you rivet. I was expecting to see a hard bend on the edge, like practically every other sheet I get shipped to me from whoever I decided to by from that month. Even then, there's very little than can't be used unless it's something like a wing wing where the edges have to be perfect and you're using practically the entire piece in one shot.

It doesn't look like it will effect the structural integrity any, it's 

just cosmetic. Some of that may get covered up by the nose skin. If it 

bothers you, you may be able to work the wrinkles out by rubbing the 

metal with the back of a spoon. I think the procedure is described in 

the archives somewhere.

Is this the way it came out of the shipping crate?  Does the crate show signs of being damaged on that end?  If so, IMMEDIATELY take a picture of the part AND the crate!  You have a claim for the part that was damaged.  I personally would NOT put this wavy skin on my airplane and have it look like this.  If the shipping crate wasn't damaged, I would CALL Zenith immediately and let them know how you received this skin.  It should NOT have any waves whatsoever on it.  From what I can tell from the picture, it looks like the end was "jammed" by something.  As I said, take pictures and call Zenith.  They can get a replacement skin sent out to you and possibly help you file the claim from the people that delivered it to you.  You want your aircraft to not only function well, you want it to LOOK GOOD TOO, right???  I would certainly would especially when you are going to spend this much money on your airplane!

When I received my rudder kit from Zenith, the rear skin has slipped

down into the crack 

between the side and edge of the crate.  There was about 2in protruding

from the crate that had been bend over. I had to disassemble the create

to remove it.  Zenith replaced the skin, didn't even want pictures.

It doesn't look like there is any crease at all, I'd shoot them over an email let them know it MIGHT need replacement.  When you get your skeleton complete put it on there and give it a shot.  If you can see it I'm sure they'll send you another without a doubt.  The folks at Zenith are quick to send out replacement parts and are always more than reasonable.  Assuming you don't live in Alaska or HI you will usually get your parts within a week.  



Build your skeleton, enjoy, pay attention to the drawings and you'll be fine.



I find it best to save all my scrap screw ups, especially angle as it can be used in many places in the event of a mishap.  I also prefer to wait for my next screw up, so I can get multiple screw ups in one shipment.  I've actually only had to have 3 parts replaced (trim tab on elevator, don't ask... HT rear former on fuselage, don't ask...  And FFT tips... damaged in shipment).



Don't let these things hold you back.  You still have an entire airplane to build, there is always something else you can be working on.

Thanks everyone!  Man you guys are quick to help!  Everyone brings up a valid point, I think as a precaution to possibly needing a replacement down the road I will send them an email with pics just so they have it.  This way if the waves get worse when riveted or the pre drilled holes don't space out right I can contact them.  However over the course of the build I'm sure there will be plenty of structurally sound parts that get nicked up or blemished plus I'm not so sure that the waving wont come out when its riveted.  Either way this forum has been great at helping me out as a beginner and I really appreciate it!!

I had assumed that the mis-packaging of my kit resulted in the same corners being crumpled to a small amount - and my skin was 0.020" thick. I think you should call Zenith and make them aware of the issue. It appears to be a trend.



In my case the shape of the crate was a simplified trapezoid that loaded those 2 corners if the crate was banged or dropped on that end. It could just as easily been shaped to match the cut end angles of the skin then there would have been no risk at all. Maybe they will make that change.

My crate was completely undamaged except you could tell that it had been "set down hard" on that end. The problem is that the angle of the forward edges of the skin is more acute than the angle of the crate so the skins inside simply shifted and crumpled when the crate was mishandled.



That is why I thought that letting them know might get them to change the angle on the end of the crate and keep others from the same experience.
