I see a significant difference in wing and stab, the heart of any pattern model. Root to tip ratio of the Zegue looks to be around 2.5:1 vs around 2:1, which moves the AC of the wing closer to the root. Should behave better in windy conditions. Zeguw appears to have thinner sections which may mean faster flight speed and could be a bit of handful for constant speed. The shape of Zegue fuse from the side view may be slightly nicer lined but thats a minor point. The ventral subfin of the Zegue could mean better picth couple character in knife flight

Wing position relative to stab relative to thrust line appears a bit different. Hard to tell but the angle shown, the Zegue appears to have little dihedral as it should for no roll couple...the Integral seems to have very similar dihedral, but with a lower wing position, there may be some roll couple.

I would love to hear the flight report Jason. Stop answering all these emails and get to work. (LOL)
