Strange debate...
Why is it only perttime who have hit the nail so far?
For small 3D foamies the main factor is weight, or lack of weight! For the size I would say 180 gram AUW is a bit heavy. 400 gram is... well, it is not a good 3D-plane any more!
My choices for planes this size: AXI 2204/54 and 2S or 3S 450mAh LiPoes. Motor, ESC and battery weight appr 80 gram total on 3S. (Less than 3oz I think) Performance is less if you put in 15gram servoes instead of 6 gram servoes
