I'm willing to bet that the ventral T-canalizer makes the entire package very effective. It looks like the area of the two canalizers is equal to the one canalizer of the latest iteration of the Axiome. This airplane looks "right" the last Axiome with the tiny Saphiresqe wing and giant canalizer didn't look good on the ground or in the air. This airplane probably kicks substantial ass.

I'm interested to hear about the new YS as well.
