The Ultimate can 3D, but it certainly is not designed for it, as least not easily. For roll rate, pitch rate, and yaw rate, you can check the video in rolling harrier, waterfall, torque roll and flat spin respectively. By the way, my Ultimate w/ YS 140 DZ weighs 12 lb. w/o cowl, spinner, & wheel pants. Fully equipped, it's in excess of 12.5 lb. Definitely not light enough for 64" length airframe.

If you go for the DPM Edge, and want the best power to weight ratio, get YS 160 DZ, mount servos up front. It will balance. Plane will be 13 lb. When propped correctly, the 160 DZ can pull 24 lb. My 140 DZ pulled 21 lb. swinging Bolly 19x6 @ 10200 rpm.
