I set my cg back on my Ultra B 1/8". I know not much. I also set my CG back 3/4" on all my small bandits.
As you have noticed BV's stuff flies a little nose heavy. Which, is how I like MY airplanes to fly, but not as much as BV usually recommends. I don't think the Ultra is as nose heavy as the small Bandits usually are.
I found that the Ultra will pitch up on Flap deployment and with crow (I use 3/8") it pitches up even more. I found that I needed to mix down elevator with both take off and landing flap settings.
The elevator has alot of authority (unlike the small Bandits which can run out of elevator if you make your final approach with the nose up) on final and the Ultra B liked to be on final with the nose up using throttle to slow the decent. I actually touched down with 1/8 throttle or so.
SSOOOO, on final the Ultra B is not like the smaller bandits (Bandit ARF, Super Balsa Bandit or Composite bandit). The ultra comes in with a touch of nose up.
I also found the Ultra was not as "quick" as bandits, probably because it's almost twice as big!
