Hello to everybody, I have such a big problem with my quad copter because it doesn't take off at all. Even with maximum throttle, nothing,motors spinning but it won't take off.
My quad copter configurations is:
APM 1
4 x NX-4008-620kv Brushless Quadcopter Motor
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=17924
4 x ESC Turnigy 25A
Props: 9x5 gws
Battery: Zippy 3s 11,1V 4000
It is a custom frame that weights with all the electronics on it about 1.3 kg or 2.87 pounds
I want to mention that the copter is X frame orientation, all the props are blowing air downside, direction of the motors is correct, 2 pusher props and 2 puller props. Would be very grateful for any kind of information that could help me with this flying machine.
Thank you for your time

Are you sure the props aren't on upside down? They'd still be blowing air down, but it would be very inefficient. I think on GWS props the lettering is supposed to be on the top.
Those are also very small motor/props. The smallest we recommend fora standard-size frame is 850 motors on 10" props.
