Ahaacobbler, The stir stick mod came about out of annoyance, I was annoyed at a jet/mono mod that refused to fly(and still does refuse to fly) and when I picked up my regular flyer the winglets had been sliced up badly. I was tired of taping wings together.

The goal was to keep the wing from flexing so much that allows the prop to eat a hole in the lower wing. I started with 4 toothpicks but discovered a flaw with that idea rather quickly, toothpicks are sharp. The toothpicks did prove that the concept could work.

The concept is that by keeping the wing in positive contact with the fusealage(fuse) the energy of the motors is used more effeciently(sp?). When the plane has all 4 wing surfaces attached to each other force, or energy, is transmitted to the lower fuse via the lower wing. The wings also flex under load, this dissipates the energy and tears holes in the lower wing. On a new AA removing the lower wing and spars could leave you wondering whether the plane is flyable.

With the single stir stick mod, one per wing, the plane keeps an ability to have wing roll and transmit the energy to the lower fuse to help bank. With a plane in this mode you need to practice more, because you can turn hit the gas and flipback to pretty close to your original heading. I consider my personal single stir stick mod as my stunt plane. The other stir stick mod is the double stir stick mod. This is 2 stir sticks per wing meeting at a single point on the fuse. This keeps the wing from rolling as much by transferring the for both the front and rear of the wing to the fuse

These mods should not change the angles of the wings. The question of the wing coming loose from the fusealage is due to more pressure on the "glue" used to hold the wing to the fusealage. A bit of scotch tape, I recommend the purple gift tape it is stickier than the green stuff, will solve that problem. For info on lengthes et. c. check the mod page.

Sorry for being such a blowhard, did this answer your question?
