dihedral question

[Bob Kane]

I concur. I built and flew an Ultimate Kaos for two
years. It was built per the plans and flew great. It
will hold knife edge in either direction with no
elevator correction. I still fly the plane for fun, it
now sports a Jett .76 in the nose. Talk about vertical
!!! (Don't try this for competition. The Jett motor is
very powerful, but very loud)
