RE: Why add all the CX2 aluminum parts???
RMG your bang on with your comments. The large majority of us that have all CNC birds do one major thing to counter the weight. We all run the Xtreme 180 motors, silver brushes and all of us have higher rated lipos. I personally have been a little rough with my CX2 and with the exception of the airframe, servos and swash I have broken, bent and otherwise destroyed every part of the heli. I upgraded to all aluminum, saves a ton on plastic parts. The only real kicker with CNC rotor hubs is instead of shearing the blade pins, now it bends shafts. One huge upgrade regardless of weight is blade grips, they are a shaft saver! Since moving to the Xtreme grips I have only had to replace 1 outer and 1 inner shaft, and the reality of that is silk plants in the living room can destroy a heli quicker than flying into a brick wall.
