For all these people that are concerned about how to get in it
   and how to park it in your garage.
   I used a pneumatic bellows actuator. If somebody
   can come up with a simpler, lighter weight, more compact
   actuator when stored please feel free to submit a sketch.

   The wires running back to the fuselage are necessary to stabilize
   the bellows. Otherwise it would buckle outward. This is a lot like
   a bicycle wheel or the London Eye. It is four inches in diameter
   with an area of 12.56 square inches. At 100 psi it will generate a force
   of 1256 pounds to lift the entire gross weight of the aircraft.
   An on board small air pump could be electric or it could be
   driven by the engine. It also provides a bit of cushion when
   landing.

   This scheme is also less drag as there is only one intersection
   for a larger top rudder.

I like the concept, Paul..

However, even though an electric actuator might itself be heavier, you
wouldn't otherwise need to carry an air pump to run it.

I would love to see an overall scale drawing using an electrical
actuator :) Space is at a premium.
