Aligned forward and aft horizontal stabilizers, clamped and drilled for bolts. The laser level has the ability to project a vertical and horizontal beam at the same time and is fully adjustable up and down on the mount and is self leveling. Prices have come down for this laser levels over the past years and you can find other brands out there that will do the same thing. Just make sure it can project the vertical and horizontal beam at the same time and is self leveling. Bolts for the horizontal stabilizers included in the kit for the aft stabilizer lacked enough washers to be able to adjust the bolt to only having one to three threads showing out the nut. I purchased more AN4 hardware to cover this.
