Stab installation

Before we start the wing and stab installation, it time to mark the installation locations. The Genesis makes it easy. There are molded in reference dots and circles for the wing and stab tube. The molded in dots gives you an incidence reference line. I use masking tape to mark up the fuselage.

Next locate the stab tube hole. After I cut the holes in both sides, I install the tube socket and start checking my alignments. I measure the stab tips relative to the centerline of the fuse to make sure it is aligned. Then I use right triangles to make sure the stab is square with the vertical fin. I cut the stab tube holes in the fuse a little bit larger. I use 1/64 plywood shims to center the stab tube socket. After is all alligned, I tack in everything with thin CA. I check one more time and then I mix up some epoxy and milled fiberglass to install the socket with the fuse hard points.

After the stab tube fillets cure, it's time to install the wing. You will notice I install the wing tube socket in the fuse with the furnished plywood rings. Remember to grind away the inner fiberglass and styrofoam layer where the ring attaches to the fuse. I install one ring on one side without the tube. Then I cut the hole on the other side. There is some trial and fit-up of the wing. After everything aligns, I install the center tube socket and other ring. Here it is critical to align the wing with the fues and the stab. I use balsa shims to make sure the wing is aligned with the fuse sides. I take a string and measure from the wing tips back to the vertical fin. If all is aligned within 1/16 inch, it is time to install the other support ring. I do sight the wing with the stab to make sure everything is parallel. I simply make a wedge to ajdust the free side. If everything is aligned, I install the other ring with 5 min epoxy. After this, I go back and mix 30 min epoxy and make a fillet to attach the tube with the ring and fill in any gap of where I removed the inner layer of styrofoam.

Take you time and do not glue in anything until every thing is aligned. Later I will set the final incidences when I install the wing adjusters and the stab locator pin. I useually wait until I have finished sanding the wing and stab before I set incidences.
