RE: rudder control
The pictures show a twin. You aren't, by chance, building a twin for your first plane, are you? If so, is it electric or glow powered?
While you CAN build something like that, (and I agree with Dennis about the control linkage, btw), I think you'd be much better off building something more conventional your first time out. Twin booms are twice as many things to go wrong, and twice as hard to get everything aligned correctly.
So, I agree with Minn, I urge you to stick to something "simple" for your first try. After you get that working, and see how stuff works and doesn't work, then you can go crazy. In the long run, you'll be better off, I suspect.
