I was wondering how a 33% Aero-Works Ultimate would compare with a 35% Extra or Edge in terms of IMAC. I know the Ultimate is good at 3D, but I am not sure about IMAC sequences. Any help would be greatly appreciated.

Thanks,
Chris

Bipes take longer to set-up. Thrust angles are more critical. You need quite a bit of rudder to aileron and elevator mixing. It takes a while to get it right.

Once set-up properly, they are competitive with the extras in the pattern. The weakest trait is that the increased weight/drag hurts on up line snaps. You have to really manage your energy and plan ahead. The two biggest strengths of the Ultimate are the rudder authority and very axial (and fast) aileron rolls.

If you want a challenge and a crowd pleaser, go with the Ultimate. If you are very competitive, go with the extra......they are easier to set-up.

One thing for sure, properly setup, the Ultimate will match any monoplane out there. They DO take more horsepower for vertical maneuvers, especially snaps, but that additional drag and low wing loading allows you to fly slower though the sequences giving you more time to think.

Thanks for the info! I learned quite a bit.

There's a guy that flies IMAC in WA and OR with an H9 Ultimate. If you go to a few comps, you could probably talk to him. It's ridiculously slow flying, even straight down. I bet you could "dial" out the rudder nasties pretty easily and you'll have plenty of time to drink coffee or smoke in-between maneuvers.

I have a small 54" Goldberg Ultimate and would not use it for IMAC. The rudder has a strong proverse roll and positive pitch. I think the newer models have shorter cabane struts, less stagger, and less sweep. It all adds up to more honest handling (although less true to form).

I say go for it. Besides, I want to see more bipes at the IMAC events.

Yeah I have seen that person with the H9 Ultimate it seems to fly pretty well, but i am 15 and flying in Intermediate this year so I don't want to get something that might not perform as well as my Extra. So I think I will pass on it for now.
