After serious contemplating and conversation and a ton of research I have decided to scrap the original horizontal stabilizer and elevator configuration. The elevon idea was the prefered method I had chosed years ago when developing this airframe idea. The 100% mechanical mixing was actually very easy to design but I was already experimenting with so much I felt that maybe I should just go with the original RV-3 tail design. After seriously looking into the design of the horizontal stabilizer attach point to the fuselage I became increasingly unhappy with the degree of rigidity or lack of it to be more specific. I was concearned that there would be too much flexiblity in the tail arrangement and was affraid it could induce flutter. So here we are, my original idea is born into the hurricane out of necessity for a rock solid and very rigid design. I have been using sizing formulas to get an acceptable size of each elevon based on the position relative to the wing. As it turns out there is a quite large acceptable range for elevons depending on desired amount of stability and manauverability. Basically, it will be somewhere between 38 and 44 % of wing area. These photos show the basic supporting structure. The elevon spar is built exactly like a trailer axle. Tapered roller bearings allow for smooth operation. The spar is strong enough for a 200 lb person to jump up and down on it if it wouldn't tip the airplane over.
