F330 Quadcopter build won't fly!

I have built an F330 quadcopter but cannot get it to fly. As soon as I use the throttle the motors just continue accelerating without any further throttle input.

Any help appreciated as I have no idea what is causing this problem. I have swapped transmitter, different speed controllers, different flight controller and the problem still persists.

My quad consists of the following:-

F330 frame
4 x Motors Emax XA2212 1400KV Brushless Motors
4 x FLYCOLOR Simonk Series 2-4S 20A UBEC 5V/0.5A Output Brushless ESC RC
4 x 8045 Propellers
1 x Battery 3S LiPo 30C - 2700mAh - 11.1Volts/30Wh
1 x CC3D Flight Controller - OpenPilot CC3D Flight Controller Staight Pin STM32 32-bit Flexiport

The weight of my quadcopter including battery & rotors is 691 grams.

I am using Libre Pilot GCS with a Spektrum DX6 controller.

Someone please help - I just want to get airborne!

My guess is that something has not been setup correctly, either your radio end points/calibration so I suggest you go through the setup wizard again.

We also have this guide that talks you through the setup process. Its for a ZMR250 quadcopter, but the principle is the same:
