The C-3 would likely hold up a 1 1/2 sized person. But may require more than 30hp rather than the 26hp to 30hp of the C-2, just saying that it wouldn't require the 36hp to 40hp if it was being flown single place by someone "big boned" but weighing less than two people.. There are some horizontal V-twins over thirty hp that weigh less than the 118lbs of the Aeronca E117 36hp to 40hp.

Welch OW-5MOW-5M is interesting.

The biggest drawback of the Luciole is its very limited payload, around 100kg pilot AND fuel. I would not have enough fuel for a single circuit. This was the deciding factor for me to go with the SD-1.

OK, lr27, I see what you mean. My thought was to use a high-cambered, high-lift airfoil like the Eppler 561 on the main wing. The E561 can reach a CL of about 1.8 at 13 degrees, so the idea would be to make sure the canard stalls out before the main wing hits 7-8 degrees, when the main wing would still be at a very respectable CL of 1.5-1.6 or so. But if the canard used the same chord and airfoil, but at 50% higher wing loading, then it would stall out while the main wing is at just 1.2.

What about using a very high lift airfoil on the canard, something like the Goettingen 523, which has a maximum CL of almost 2.2? That would mean you could get the main wing up to about 1.4 before the canard stalls, and the main wing would still be a long way from its own stall AOA.

A high cambered wing on a canard airplane won't do much good unless the canard is capable of an even higher Cl.

Excuse me but doesn't the Mitchel Wing have the possibility of meeting the requirements of a 24 hp single seater.

Now that I think of it, the Catto Acro-X layout might work here with a lot more wing area and tricycle landing gear on the fuselage.
