Need help

I just finished building my 1st Quad. I think everything is working. All powers up but cant get it to work so I need some help from you experienced guys to help me find the problem. I did my best trying to find the right info to set up my transmitter. I think this might be the problem. I just cant find anyone that knows how to get me up. Once I get this all figured out I will add a GOPRO 4.. Any help would be appreciated greatly. I cant fly until I get it fixed. Here is the parts list

Hover things Flip Frame
Naza lite controller with GPS
Motors 2208-18 x4
Standard power distribution board
White/Red LED'S to indicate front of Quad at night.
Speed controllers Hobby king 20a UBEC 5V 3A NIMH LIPO 2-4S
Spectrum AR8000 RECEIVER
Spectrum DX7S Transmitter
Turnigy 2.2 LIPO battery 3S
 
If the receiver is powered, there should be at least one LED lit up on it, and that LED should indicate whether it is bound to and receiving signal from the radio. I think the Spectrum binds by putting the receiver in bind mode with a jumper wire or plug that comes with it, and holding the trainer button down on the radio when turning it on. Here's a link I found that seems to address your gear: http://www.xflysystems.com/blogs/ne...rum-dx7s-dx8-etc-ar8000-failsafe-for-dji-naza

If you believe your radio and receiver are bound, connect one ESC lead directly to the throttle channel on the receiver with the battery connected (so the ESCs are powered) and run the radio throttle up and down to see if the motor spins. Obviously it's important to NOT have a prop mounted when you do this. If the motor does spin, the problem is likely related to the flight controller.

You may also need to do an ESC calibration procedure. (something I will remind people of forever after my recent experience!) That is generally done either with or without the controller inline, by powering the radio on, turning the throttle up full and then powering the quad. The actual procedure is determined by your ESCs.

It's just a matter of breaking the problem down and isolating it.
 
When I use the Naze Software it doesn't seem to talk to the the transmitter when im doing the cal.. The build part was easy. It's the software part that's being a PITA.. The 1st link for fail safe I don't know what switch is for that on the DX7? I know I can set that just don't know how.. For the motor test I cant get the transmitter to turn on the Motors? I need some assistance setting up the DX7 for use with my Quad. I even used someones settings for a DJI F550 That did not help.

I need to get some basic functions working. The 1st is to get the DX7 set up properly and the 2nd is the transmitter talking to the Naza for TX calibration. When I bind the led is solid green that's what I want. After that I cant get anything to work?? I really appreciate any help
 
I have made some progress, I was able to get he Transmitter working and I also tested the motors. 1 was bad it would not spin like the other 3 did. I have 4 new motors on the way.
 
I got the new motor installed now all 4 motors are working for the throttle test.. I now need some help getting the DX7s set up properly. It gives CFG error anytime I turn on the transmitter. I went through the settings multiple times it still gives the same error. I don't know if I need to use a programing card on the ESC? that's next if it is needed if not the quad is done and ready to fly I just need to get the transmitter working properly with the GPS setup and also the fail safe for it to go home and land.
 
(that "bad" motor could be ok!)
Normally you need to calibrate the ESCs. (Man did I go through this one!) Probably best to look for a guide on YouTube for your setup, but generally,
you connect the ESCs directly to the receiver (not the controller).
You REMOVE THE PROPS.
Turn on your radio, run the throttle up full.
THEN power up the receiver.
The ESCs should make a noise.
Throttle down, they make another noise,
then power cycle everything and you're good.
But that is a "generic" procedure -- your equipment may vary.
If your ESCs do not have SimonK firmware, they won't throttle up and down real smoothly so don't expect it. But I had one that started right away and the others didn't start together either BEFORE the calibration.

If it turns out all your original motors were fine, it just means you have a head start on your next quad!
