I've flown the AW 540T with a saito 100. Don't bother. It wasn't particularly precise and didn't 3-D very well.

I have the UCD 60 W/saito 100. This is an extremely versatile plane. It's just as at home doing high speed inverted passes on the deck as it is hovering or flip-flopping.
It'll even do rollers but the coupling's too much for serious precision aerobatics.

I don't have any experience with the others. Good luck with your decision.
