The T canalizer does work, and very well, by reducing the P Factor the air gets to the vertical stab and rudder on both sides with better laminar flow, so the rudder is more effective because of "cleaner" air on it; And on any pitch angle different than straight and level flight it helps on the rolls a lot, more like a biplane, I fly the Axiome and the Amethyst, and they are very similar in flight.

I flew my Osmose without the canalizer and it flew like crap! so the canalizer does a lot, I needed to increase the rudder travel to almost if not double throw without it.

Jim, I think you flew your Osmose without the canalizer if I'm not mistaken?

Best regards
