Hello Everyone,
Everday I feel like a new light bulb is going off in my head which is great.
My New Challenge. I have my Quad ready for flight all it wants to do is flip over.
The quad seems pretty balenced and all four of the motors and ESC seem to be matched.
I have the proper blades (11" push and none push) on the right motors going CW and CCW.
One thing I have tried is to hold the quad above my head giving it enough throttle that it feels like it is trying to pull away from me and testing pitch and roll but it desn't seem to having any effect.
When I have the Quad hooked up to my mission planner and test the RC is seems to be set-up correctly.
Any Ideas?
Jason

Jason,
I've been mining your previous posts and unless it was changed, your Futaba was in ACRO (airplane) mode at one time.
Another possibility is that somehow you have an advanced airplane feature set, such as mixing elevator and ailerons. This would be bad.
At this point, go back to Mission Planner and confirm that only one stick movement moves one of the slider bars in the calibration. You sorted out the Yaw issue in THIS post previously.
As previously advised, you only need the 4 inputs to get this bird in the air. If Yaw and Throttle are sorted out, that just leaves Pitch and Roll... one of which you are having trouble with.
That Futaba transmitter is a complex radio to setup. You are building up skills that will help you on your next multicopter build. The first one is always the hardest.

The APM looks correct from a 'front-back' relationship. You are good there.
The PDB has orientation simply for motor reference connections for the ESCs. It has no sensor electronics.
This really only leaves your RC inputs and mode setup or firmware (which we seemed to have sorted out previously).
BTW, what radio system are you using? If you have a 'computer radio' that has heli or airplane modes, you should be set up in *airplane* mode.
Here is a graphic of stick control. I have used classic quadrotor phrasing and added the equivalent RC airplane phrasing that is probably on your receiver.
Your throttle input/output is obviously correct. Don't mess with it.
Confirm your other three.. it is *very* easy to install the wiring one pin off.
In fact, you could use your suspension rigging to check/confirm if Yaw is working properly. Simply throttle up some and yaw. It should start twisting the bird left/right. If not,either your receiver connections to the APM are mixed up or your radio is set up incorrectly.
Hang in there Jason, you are almost ready to start breaking props due to lack of skill! ;)

If you have the room and are not sure of the results of a hand-held test... I recommend suspending the airframe by the arms of motors 1 and 2. This will let you spin up the motors to near lift-off RPM and check your pitch for reversal.
My pitch was reversed when I tried my maiden flights. I changed it at the transmitter and have been flying since.

My hex did this when I last updated the firmware. After the update the configuration was set to "X" when it should have been "+".
While you are in the CLI, check your frame type as indicated in THIS picture.
The commands will be: 'setup', and then 'frame'.
You do NOT want the response to be like in the picture above.
The response you want is: 'Quad frame' , and then either 'X mode' or '+ mode' depending on what you selected.
This may seem trivial but a new member spent weeks and many broken props before discovering he had installed Hex firmware rather than Quad. His quad also kept flipping while trying to lift off.
CLI is a right of passage for all DIY Drone members. Advanced cultures have advanced initiation rights. Enjoy it. ;)
Good luck!

Have you run the Motors test in the CLI?
I don't know what this means: "(11" push and none push)". You should have two pushers and two pullers.
