RE: Will increasing the thickness of a biplane wing decrease the stall speed, or just add useless dr
Bipes simply can't get too light -
Mike Cross is very good at keeping things light - he also did the Great Planes 330 - a terrific design.
I first ran into him when he was flying one of my IMAC designs - the EXCESS (doubled as a 330)
In my little foamies - I strive for zero weight - -so far -no cigar - but as you guys who actually fly have found out - the planes take on a whole new character if the weight is at rockbottom
even the CG becomes very non critical (there I go again )and allow you to run the CG around as desired for 3D or best precision stuff.
