I think g 2 isn't the best sim for 3 d. I never could get it to do much. I bought aerofly pro deluxe and it is unbelievable how realistic it is for 3d. I highly recommend it.
As for a 90 size pattern ship that 3d's. Look at the 3d quest90 from ultra-rc.com. Might be a good one for ya. Are you going to fly at any pattern meets? Hope to see ya there.
