Make sure radio is calibrated, and try the motor test in MP to make sure the correct motors are spinning up

  At last got it right! it's flying! But not yet very precisely..
  
  So first of all: Mossbackfarm, Cala and anyone else who replied - Thanks a lot!
  
  Now for the fine tuning issues: Need it to take off as symmetrically as possible and to hover over a position, as stable as possible - any advice?
  
  Need a 1-1.5 kg payload power and no need for speed or acceleration at all - Only stability at a 5 meter hovering height is what's important here.
  
  Any specific type of frame, motors or props to recommend in relation to such a mission ?
  
  Thanks!

    Good!!! now, if flies reasonable set mid throttle http://ardupilot.org/copter/docs/ac_throttlemid.html
    
    Read here: http://ardupilot.org/copter/docs/basic-tuning.html
    
    And try autotune: http://ardupilot.org/copter/docs/autotune.html#autotune
    
    to be more precise flying.

      Thanks Cala.
      
      Not very simple, are these fine tuning methods,,

        Roi, autotune is really easy, only go to an open area on a calm day, as more you go learning as better your copter going to fly but, at the begining, only you can fly is a big thing, It's happen to me.

        Yes, i'll probably try it in an open area..

        Hello people,
        i'v changed the frame, props and motors - but kept the entire setup exactly as it was with previous components - but yet, the new drone won't get off the ground.
        
        Attached below are pictures of the new drone props setup.
        
        Here is the motors model:
        https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct...
        
        Here is the props model:
        https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct...
        
        Here is the frame model:
        http://www.hobbyking.com/hobbyking/...otal_width_EU_warehouse_.html...
        
        1. The front right prop is a CCW type, the motor attached to it is spinning CCW and it is connected to the black,red.white wires - which is channel number 1 and the only channel that has 3 wires and not just the data. Of course data + and - are connected right.
        2. The rear left prop is a CCW type, the motor attached to it is spinning CCW and it is connected to the blue wire of channel number 2.
        3. The front left prop is a CW type, the motor attached to it is spinning CW and it is connected to the yellow wire of channel number 3.
        4. The read right prop is a CW type, the motor attache to it is spinning CW and it is connected to the green wire of channel number 4.
        
        p.s.
        i'm using a PixFalcon FC:
        http://www.hobbyking.com/hobbyking/..._Micro_PX4_Autopilot.html?str...
        
        What could be the problem?
        
        Thanks a lot.

        If the front right prop (ie top right in your first picture) is spinning CCW then you have the wrong prop on the motor.
        
        For the props that you have mounted on your motors then top right/bottom left should be spinning CW and top left/bottom right CCW.
        
        I am not sure what rotation you are wanting but that is what you have got.
        
        Peter

        Thanks Peter,
        
        Finally got it right, it's flying nice now..

Here is the FC i have:
PixFalcon Micro PX4 Autopilot

I don't seem to find decent documentation.

When i connect the 4 motors to channels 1234, where channels 1 is a Futaba with black, red, white wires and channel 4 is blue wire Futaba with only data and channel 5 is yellow wire with only data and channel 6 is green wire with only data - i get 3 motors turning CW and only 1 turning CCW.
