Default Wright flyer balance??

I have a friend who recently cobbled together his very own version of the Wright Flyer... It's essentially two, stacked Sig LT-40 wings (with ailerons, naturally), as well as the dual canard in the front and the dual rudders in the rear. Powered by YS 53 mounted centrally between the two wings. Sounds, iffy, right? Indeed is was...

His first attempted flight resulted in a gentle climb (about 2-3 feet) followed by violent pitch straight up, stall, crunch.

When I talked to him about it afterwards we both agreed that either the canards had too much throw (I suspect they're pretty sensitive) and the balance was way off... He balanced his contraption on the main spar of the bottom LT-40 wing (where it should balance were it attached to an LT-40 fuselage). Since there's no tail-plane in the back of this model, I argued that the balance should be at (or even in front of) the leading edge. But, we have no plans and no reference materials... except this forum...

So, my question is... where should the Wright Flyer balance? Anyone ever sucessfully modeled an R/C version?

Thanks in advance
