Default RE: Dihedral question
ORIGINAL: pjwright

I'm in the planning stage for an SPA plane for next season, looking at a 1969-vintage design which (naturally) calls for a good deal of dihedral. I'd like some thoughts on the performance and handling implications of modifying the amount of dihedral, as shown in the attached diagram.
Thanks!

PJ,

See the pictures I did make a few years ago. One is photoshopped of course.
Reducing dihedral doesn't have any profit IMO only risks will be more in windy circumstances.
My planes always do have the normal dihedral.
