The same questions get asked, the same issues pop up.
You guys can reply below with any additions/corrections/changes , then i will move it to the wiki
Step # 1 - Get the Radio Setup
Make sure your radio is ready, we dont want any mixes set up, no heli swashplate setups or the like. Just 5 channels set up for Roll(aileron), Pitch(elevator), Throttle , Yaw(Rudder), and a 5th channel for Flight mode - this 5th channel you will drive from a switch , such as "gear".
Ensure all endpoints are set to 100% and all sub mixes and trims are set to zero.
"what if i only have 4 channels ?" Well, at this stage, the work-around will be to use a Y lead, and connect your throttle channel to be used as flight mode as well.
Step # 2 - Set up the ESC's
Set up the low voltage shut off, timing, battery type, startup etc, by following this guide http://wiki.openpilo...ded ESCsettings
Then using your reciever and transmitter, set up the throttle input range on the ESC.
Consult the literature with your ESC, for most it is as follows, you will need the motor connected (prop off for safety) to hear the confirmation tones from the ESC (it uses the motor as a speaker)
-Turn on your transmitter
-Set the throttle to MAX
-Plug the ESC into the reciever and power up
-The ESC will make a quick series of beeps, swiftly move the Throttle to MIN on the transmitter, the ESC will Beep again (a few times) to confirm the throttle is set, and will inialise
-Making sure your motor is secure, use the Throttle on the transmitter to spin up the motor, make sure its smooth, the throttle range is correct, and the motor is spinning in the correct dirrection.
Step #3 Connect the CC board and select the Frame
Now - first off, i am NOT covering updating the firmware in this article, that will be done seperately
Important - make sure the GCS (Ground Control Station) Software, and the firmware in your copter control are matched.
Plug the copter control board into your PC, and run the GCS software.
The GCS Introduction page will appear

Select the "Aircraft Type" drop down box and click on "Multirotor", then in the "Frame Type" drop down box, pick the multirotor of choice (in this case a Quad X)
Next assign the 4 motors to output channels (choose from 1-6, 7 to 8 are not available via the PPM outputs) these are the channels on the CC board that you will plug your brushless ESC's into.
At this stage, grab a piece of paper, and sketch your multirotor configuration, and number the motors, channels, and direction of rotation. The direction of rotation is very important.

If you are feeling really keen, you can also modify your "Throttle Curve" to match the one in the picture below, setting the 25% throttle to about 50% output, and dropping the 100% throttle down to about 90% output.

As a quick note, 75% output power is about 50% of your total motor power.
It also give you a less "sensitive" throttle stick and allows for easier control of height and power
But , dont get to concerned, we will fine tune this later, so leave it setup as default if you like.
Now ONE LAST CHECK - WARNING - THIS IS A BUG , AND CATCHES MANY OUT ! check the "MIX LEVEL" all values should be between 50% and 100%, 50 is a good start point - if they are "0" ( and the bug causes this) - you will have NO control over your multi apart from throttle ! not a good situation !
