The Hobbyking H4 Copter Multi-Rotor Quadcopter Frame 470mm is well crafted. Carbon fiber motor and body plates with aluminum arms and frame. My only gripe is the motor plates where you screw the motors on.. it would have been perfect if it can readily accommodate the Turnigy Multistar 3508-640Kv 14Pole Multi-Rotor Outrunner.

Heres the build pixs so far:

with arms:

Finally with motor and escs:
