As a genuine 3-channel model, it handles very well and can be even flown without elevator - like any typical trainer model of the 1960s. It flew well enogh with a .19 glow engine but could cope with...

:) Looking good. Guess credits are due to Abbott and Doenhoff for their book and Stefano for the software.

That's an odd request, isn't it? ;-)
Anyway, maybe they didn't find it worth it to publish the coordinates of the symmetrical airfoil twice because the basic thickness form would do.
And it's not...

Nothing wrong with bumping an 8 years old thread, just stressing my memory. Going to the hard-disk memory of my PC may help though.

Meseems you're fixated on having the C/G at 25% MAC. Actually, the location of the C/G is heavily dependent on the airplane's configuration and even the wing's airfoil.

The C/G calculators usually...

Looks wonderful! It would be a shame if it would never fly, so couldn't it be flown at the AMA field in Muncie before putting it in storage? There should be expert pilots (with insurance) who would...

I think you can't win. A gyro in damping mode makes the movements slower but still you can't see them far away. In lock mode, it's the same like a helicopter's tail gyro: there will be no yaw but you...

Wow, the whole airplane is one complex shape! Very unusual and somehow "organic". Now I see why there are skids under the stab. The open-rocker engine matches this piece of art. :-)
