Ardu-copter flipping sideways instead of taking off

roineust thought this was worth mentioning said

i have built an Ardu-quad-copter around the HobbyKing PixFalcon flight controller.
i'v made a serious effort to try to learn how to calibrate the drone using Mission Planner and tried all possible CW and CCW combinations - Yet the quad-copter just stays in place or flips on its side - instead of taking off symmetrically.

Can anyone please help me solve this problem?
