I like it, "A6-Limited" for the novice-beginner-Arseer-whatever-step. I did a rough calc to figure that your stunning success 1.9g A6-Limited using any covering weighing .35g/100 sq. could be built with 6.7 lb wood. I'm going to make one to see how it survives in low ceiling. Get to fly this Saturday, weather/roads permitting.
What design did you use?

Condenser paper was hard to come by and warped our structures. We stopped doing the project out of frustration. The next year I decided to heck with your rules, I'll make my own. Plastic covering was OK, 50% stab area, 1.90 gram minimum w/o rubber, the rest unchanged. It was a stunning success. My students loved it and they learn alot. The students went out and solicited pledges for time aloft and donated the money to a local aircraft museum. We tried Limited Penny planes the next year (seniors) and that proved too technical and took too much teacher involvement (Warping prop blades). You guys can discuss all you want, but we'll go back to my rules and just have our own contest. Limited A6 as a separate category may make everyone happy. It just might help some new kids enter your hobby.
