Don,

I too am interested in this kit. Let me start by saying that the wing sheeting is "probably" not too thin. I don't have the kit yet, but it probably comes with 1/16" sheeting for the wings. This is the same thickness sheeting I use on my 35% IMAC planes, and there are no worries or problems.

To make the aieron wire cutouts you can use an exacto knife or a dremel tool with a router base on it. All you need to do is cut a trough out of the top of the foam, and then lay a piece of string in the trough before you sheet the wings. Use the string to pull the servo wire through the wing.

To make the servo holes...you can cut them out with an exacto knife or a soldering iron before you sheet the wing. After the wing is sheeted, then you can put the servo mounts in place. There are numerous ways to do this, but here is how I do it. I use some 3/8"x3/8" square hard wood sticks and cut them to about 3 or 4 inches long. You will need 2 per servo. Then measure the length of the servo and apply that length to your servo openings. Cut 2 troughs the length of the sicks. One at the leading edge and the other at the trailing edge of the servo opening. Glue the sticks in place with some epoxy making sure they are recessed about 1/16" below the sheeting. Now take some scrap sheeting to make some "covers" for the sticks, but don't cover the part of the stick that the servo mounts to. Glue the covers in place and sand them flush with the surface of the wing. (I hope that makes since)

To cut the aieron out simply use an exacto knife and a straight edge to cut the sheeting and the foam where the direction say to.

Hope this helps, Bryan
