First off i really cant say much about the CG kit but i can Praise the GP kit.... i loved building it and it contained great quality wood and acces. The only downer was on my first flight the Ca hinges that came with it failed, so i turned to Nylon pinned hinges and have loved that plane. I modified the tail surfaces to be slightly larger and i installed a Hight torque servo(100 oz) and a pull pull Hd system and dual elevator servos..... ITs a dream to fly.... I havent tried 3d but i dought it would......Get a diff. kit if you want it... I'm pretty sure the CG kit isnt 3d either but i could be wrong... Also witha YS 1.10 Fz in the front it can haul ***** and pull out of a hover pretty quik!! I give that kit a A+++++(i would give it another + but the hinges that were with it were crappy[:@]) OTHER wise I highly recommend the Gp Extra 60 size
