I understand what you're saying but am after a different approach.

For above, when the unicycle is moving small shifts in balance of the rider have negligible impact on the machine staying up. The rider can move around to a certain extent and stay up, without needing a rear wheel (stab). Another example is a regular bicycle. You don't need really good balance to ride a bike. Once the wheels are spinning, the forces generated are so much bigger than small shifts in body weight that the bike stays up basically on it's own; the rider just needs to keep it straight.

There are stability equations that explain all this. The small changes in the CG are basically treated as zero because the forces of lift and drag are so much greater. I've been moving my CG around for 4-5 days and have not been able to change my stab trim by a single click.

I know there are airplanes out there that require load on the tail to fly straight. However I don't intend to set my airplane up that way, and I don't believe that is an ideal way to setup an airplane. There is some talk about that in the Pilot's Encyclopedia of Aeronautics too. It explains it really nicely. If your CG is forward that it pushes the nose down and needs a downward force on the tail, it is really nose heavy. It feels stable in some aspects because now the forces on the nose and tail overcome other stuff. control surfaces feel less touchy because they have to work harder to be effective.

Anyway I think I'm on the right track and have the resources I need to get where I want to be. The links above were really helpful, so thanks
