Cees,
Even then I wondered why Ed used a semi-symmetrical airfoil for a pattern airplane when the CL folks were using a fully symmetrical airfoil. Now I realize the answer was he needed a stable flying platform - one that could fly without a lot of toggle motion on the transmitter.

Yes Ben, but not only for that but more because of the high wingloading. When it became important to fly inverted and he could't not use the taildragger Orion for that anymore also because of the frise ailerons, it was the moment to design the Oldest Taurus on Earth. Because only the Taurus uses his tailcone to generate drag and lost altitude to hit the circle and get points to win during final approach. The Orion only uses his tail to be a taildragger.
Simple is that!
