3d. nice! when your building it dont over-tighten the screws. could strip the plastic. the swash plate moves down for positve pitch. loc-tite all SCREWS GOING INTO METAL especially the head area...like the spindle shaft. loc-tite the tail rotor hub and grips screws.

as for motor get something that can haul this bird. after all its not lightweight fully loaded. i run the scorpy 6 on it. very nice power. i have also run the JustGoFly 500Th brushless on it. that's nice as well. whatever you do get a motor that performs and you wont regret it. and a good motor is under 60 bucks brand new. get a decent esc to go with it. at least a 40a. 55a is ideal. i'm running the scorpion 55a esc on mine.
