I have a f550 hexacopter with a naza lite gps and FS-T6 TX. I am having trouble with the gps. If I hook the U channel on the naza my motors won't run. Do you think it is because of the tx i have? A lot of forums say I can use the two way switch for gps and manual mode. I just can't seem to get it to work. I tried using channel 5 and 6 on RX for switch but 5 stops everything and six makes it go crazy ! Also All of my motors won't spin together to lift it off ground. It just flips over. I have been trying to figure it out for weeks so Any help I really appreciate.
Help I am getting so frustrated with my f550

Right, start at the start... Yes you can use a 2 way switch for the U channel, and make it give you Gps and either atti, failsafe or manual. You need to have the Naza assistant open and connected whilst you move the receiver switch. If the chanel limits are wrong it will overshot slightly and fall into the ' failsafe zone' between settings. Adjust the Channel end points to get your settings in the middle of the options you want.
Next take off your props, go into the basic settings for the type of multi rotor it is and run a motor test on each motor in turn, and check the direction of spin against the diagram. Swap any 2 ESC leads on motors that are spinning wrong.
Then make sure that your props are on correctly... Now the motors are spinning correctly, the props should spin with the leading edge at the top, if the leading edge is at the bottom it is on the wrong motor.
Finally put the quad on a flat surface, and do a basic, then advanced IMU calibration.
When you first go to try it after, plug it in whilst flat and level and leave it to get a Gps lock. Then do a compass calibration as per the DJI manual, by toggling between gps and manual on the U channel 10 times or so, then do the calibration dance...
If all is not well after that, you have a bad ESC, motor, or have the motors plugged in the wrong ports - but you will find they out in the motor test.

Thank you rotorfreak I am still learning this. I decided to get a futaba T7CHP TX and a lot of what you said helped. I unfortunately still have a problem. When I fire up motors to fly not all propellors spin. And then the hexacopter flips over[emoji51]. I can't seem to get it to get off the ground. I set up my three way switch. Did the naza dance, but still the motors don't all run at the same time! They will run if I move stick around but not all for take off? All propellors are spinning in correct directions. Help if you have any other great ideas.

I'm glad your on the right track, and I hope I can get you there!
There is a couple of things I'd check...
The motors are mounted on the correct arms, and the model type is set correctly. In the Naza assistant, go to the model type, and check it is ticked as a single rotor hex. (is set as a quad from factory). Next, check the motor direction of your motors against the diagram of a hex in the Naza assistant. It's no good the motors spinning the correct way that the arrows show, if you bolted them in the wrong place by mistake.
In the same page then do a 'motor test' where you will get a button for m1,to m6. Click each in turn, and the correct motor should turn one or two times only. Check the spin directions against the diagram and motor body.
Do all 6 work in the motor test? Do they all spin as the diagram? Did the correct motor spin (did motor 1 button spin the motor labeled m1 on the diagram)
Do all that, a IMU basic calibration, and compass calibration in an open field and try again.
Also, to lift off you should be in gps mode, not manual. Start motors then give it full throttle until you are a couple of m of the ground. It will lift itself up smoothly with full throttle.

Once again thank you again for the help. So here is what I've done. I double checked motors and propellers. They are good to go. I don't have a motor test button on the naza page, but I fired it up and checked.
I then did the naza compass calibration IMU calibration. I also calibrated the ESC throttle distance. But still it flips[emoji16] I then made sure I had it in GPS mode and gave full throttle. It flipped over again. I am so close, I'm just missing something. Do you have any more advice for me?
