.....are you talking about the robart drill guide "jig"?

Nice simple jig. I had got mine at MH.

Hi Steve,

Yes, that jig would help to center the hinge holes, when doing a normal hinge. For the flaps. I needed to place the hinges off center, near the bottom of the flap and the wing T/E, so the problem was to transfer the flap hinge hole onto the wing and have correct alignment.

There is another device that inserts into the flap hinge hole, and when placed up against the T/E of the wing,
transfers the center of the flap hinge hole onto the wing. You buy a half dozen of these pointed rigs so you have enough to transfer all the hinge points at the same time.

What I did on my second flap, was to pilot drill the three hinge holes in the flap, then insert a 1/16th drill bit into each hole and gently push the flap into place against the T/E. It transferred the location of the three holes to the wing with proper alignment.

Here is a picture.

I have 2 different sizes of CF rod sharpened down to a point to transfer the marks. Ive painted them flourescent orange and the other flourescent green. I hoping it stops me from accidentally throwing them out. Its worked for many years now:)

I really like robarts. Took me a few tries to not use "too" much glue.

Here is a link I came across relating to Robart Hinge Points http://www.rcgroups.com/forums/showthre ... lap+hinges

It shows the "Blind Hole Transfer Punch " buttons that would be useful when hinging flaps. They insert into the flap holes and transfer it to the wing. A set of six is $7.50 US, then the shipping is $20, and then the exchange is 40%...well, you know the rest..!

I picked up a set of LED lights for the Cub, and completed the installation over the past week or so. Quite a bit of engineering involved. Things like where to place the little black controller which allows eight different lighting modes; how to install the wing tip lights to give proper lighting but also be protected somewhat. There are eight different lights, however I substituted the two landing lights with a total of 10 leds which I got from buying two small flashlights that each had five leds in them.
Each LED lead had to be lengthened so there were a number of solder joints to be made.

Here are some pictures, along with a small video.

I like the video! The landing lights in particular look quite bright!
