Sorry to hear you are injured.
The Ultra is not generally considered a 3D machine, but that makes the whole idea all the more apealing if you ask me.
I have seen some good snaps out of a 60 size Ultra, and heard of some great blenders from the 40, but never gotten good blenders on mine yet. My ballance point is just behind the spar. Been thinking about modifying the elevator/ stab to get more elevator, maybe while i am at it rework the rudder too. That might be this week's project. Should be a fun adventure.
