This made a great conduit to run the wingtip lighting wire through. Ran a piece of this through the leading-edge tube from root to tip and secured with safety wire (no space for tubing clamps, which I would have preferred), then ran the tefzel just before installing the wing fabric. If the wire ever needs to be replaced or upgraded, the wing wont need to be disassembled, and the wire is very well protected from chafe. And as always, Aircraft Spruce East folks got my order out the door well-packaged, and quickly. It is such a pleasure to have you to lean on as this plane comes together. Thanks, ACS!

All went well. We are a large department. We have a manager in the stockroom that let us know when packages arrive for us. When the package arrived, it did not contain my name, in the address, so it sat in the stockroom until I went looking for it.

I prefer this to nylaflow tubing for pitot & static lines. Nylaflow is so rigid it is difficult to work with.
