Sorry about that, reading back
So the main wing zero lift line and the fuselage datum line is parallel is a good starting point for a tractor.
my language/grammar is lousy I meant to say for my proposed canard. I know it would be different for another plane.
I was thinking about a pusher but reading your and others posts I thought a tractor would be more efficient and because it would have no undercarriage it would have to be a long nose and a folding prop.
I suppose the brief is:
More agile (from my last canard which was a 5 AR)
Cruise about 40 mph
Belly landing and 3 channel (I can't use the rudder any more)
