Hi All,
My name is Ken Lyons and I bought a CH701 kit in early 1999. About that time
my son joined Boy Scouts and I became involved, with the result that I have
been unable to make progress on the kit. For most of this time I have
followed the list, but have had no questions, and have had little to
contribute.
Now, I am now out of that activity and am starting up on the kit. I have
just completed the rudder skeleton and am starting on the skins. I was
pretty dismayed when I unwrapped the trailing skin and found two wrinkles,
one with a crack, which I am pretty sure happened when I was transporting
the skin from my place in the Spokane area to where I am working in Santa
Rosa, CA.
After looking at the next steps I figured out that one of the wrinkles was
about midway between ribs 3 and 4, and would be at a good place to install
the tail light. The other wrinkle, the one with the crack is in a less
convenient location. It is about 7mm up from where the trailing edge lower
corner should be, or 112 mm up from the untrimmed corner of the skin as
supplied in the kit. (Small Photo attached)
I can think of several options and would like to here what all the voices of
experience out there have to say. Then I will contact the folks at Zenith to
see about getting whatever is decided approved. Here is what I can think of:
1. Order a new skin. I expect this will cost the most and slow me down
the most. I really have no ides what to expect the cost to be but can
inquire easily enough. Shipping might cost a bit to prevent a repeat of what
I already did.
2. Some sort of patch. I still have the aileron from a Piper Cherokee
that I had to replace because it had a patch and the plane would not pass
the annual with the patch, so I suppose this idea has little merit. If this
option turned out to be OK, I would need some help designing a patch.
3. Round the corner of the skin enough to eliminate the damaged part. I'm
not sure how to deal with the folded trailing edge if I select this option.
4. Trim the skin 112 mm (maybe a little more to eliminate the damages
part) instead of the standard 105 mm from its untrimmed corner and make the
rudder slightly smaller.
5. A little bit of option 3 plus a little bit of option 4.
6. Something that I have not yet thought of that someone smarter than me
suggests.
I look forward to hearing from other listers. Thanks!
Ken

Hello, Ken
I suggest you consider buying a piece of 6061-T6 and make a new part
yourself.
This is the first, but you can bet it's not the last part you will have to
scrap - and learning how to make your own parts is a valuable skill.
Good luck
Carlos
CH601-HD, plans
