Ordered 2 large drill bits one for the wiring conduit, and one for the tie down hole, Also got the Hole Saw i am going to need for the pitot tube installation, I also got a pair of calipers that we have run into the need to have for various measurements. In addition we bought a bunch of suplies to work with fiberglass and to tools to sand so we can refinish the wingtip light mounts.
