the wing will now be producing a nose-up pitching moment
Hmmm - let's see: The CG has not moved, so for this assertion to be true, the CP must have moved WAY forward.
the tailplane will probably need to provide an up-load to trim
Hmmm - for the tail to provide an up-load, when inverted, I must move the stick - AFT?
Much as I'd love to, I've not flown any of these (Jungmeister, CAP 10, or Zlin 526). So I can't answer my own question.
A canard like the Rutan LongEz is an example where the \'tailplane\' produces an upload in the 1g trim condition and the aircraft is stable.
There\'s rather different safety criteria with a canard. The one thing you do NOT want is for the mainplane to stall - that means an uncommanded PITCHUP.
So the forward stabilizer is at a higher incidence than the mainplane (i.e. decalage) to insure it stalls first.
