Finally got everything on my new FPV TBS Discovery working good. First I had good GPS lock but horrible video signal. Then I got decent video but the GPS or compass wouldn't hold.
I now mounted the video TX on an arm with the antenna pointing down and the GPS puck back on the mast. It would get a good lock but the Dragon GPS took a few minutes to lock when the GPS puck was directly on the frame close to the Dragon GPS.

Now everything is working perfectly. The GPS holds about as good as it's going to get and I flew down to the end of the street and had perfect video signal and quality.

I think seadog started this spreadsheet. The only thing that is now missing is the version of the software being used.

Some problems with the Gains


Hello Everybody,

I'm having some problems with the gains since day 1, with the default settings didn't worked, and with more 3 or 4 settings from YouTube, no luck!
I must confess that I'm not very comfortable with the PID or gains... but this is the "prince".
I need to give input all the time to maintain the quad near me, normally if I leave the TX the quad goes forward and sometimes up, and this in the GPS mode.
I really would appreciate some help.
The compass calibration is made and the TX is also calibrated and using PPM.
Please check the video, some feedback is appreciated.

All the Best,

She flies!


Firstly, I want to thank everyone who has helped me. I have learned a lot and I still have a long way to go I will continue to tune my quad and eventually, get the GPS! I have FPV equipment, but I need to get more comfortable with flying.

My next step is to finish my camera mount/skids and also convert my power supply into a 12v charger for my Turnigy Accucel 6 Charger. (without it; I can't charge anything )

She Flies!!! (1 min 1 sec)


Light-weight skids to match my motor booms!
I will be attaching a GoPro between the skids.

Not sure what to use for the actual skid bars...recommendations?

Something is not right. Don't know what, your gains look fine. I made a quick clip of mine in GPS mode and it sits fairly still even in the little wind that was blowing. It was all over the place and barely flyable but I had the GPS puck close to the battery. I moved it back onto the mast and it works great now

Hey Geotete,

I'm sure we can help get this sorted out but first, we need to know something about what you know and something about your rig.

So, on the what you know part, have you read the manual, cover to cover and have you performed the setups from start to finish with complete understanding? If not, can you tell us what you may have had trouble with?

On the gear, can you post a picture or two of your Quad and tell us what is on it?
-Frame
-Motors
-Props
-ESC's
-TX/RX
-Battery
-FPV (if any)
-Telemetry (if any)

On set up there are a couple things you should know that aren't in or clear in the Manual so check the first page of this thread, TJ's Blog and read through the Naza Gouge.

Lastly, and to start, make sure your endpoints are set to at least 100% and use no trim whatsoever.

Cover to cover more than once, checked everything in the first page of this tread watched some tutorials in YouTube, and also watched Community Build Blogs, from this page, different frame but same principals.

Not 100% positive but I think I remember that the x and y placement is meant for the controller...not the gps.

I would change those settings for the controller and see what happens.. Just a thought...

And have you pointed the GPS in the right direction? The WIRE should be pointing forward and with the correct declination...or what ever it is called. Go here to find your declination: http://www.ngdc.noaa.gov/geomag-web/#declination

No the X,Y,Z coordinates are for the position of the GPS/compass unit relative to the CG.

The main unit is meant to be mounted on the CG (or as close as possible). There is no way to define an offset for that (there is with the Wookong though).

As per the manuals you are correct and that is like I did my configurations.
And the GPS is pointing to the front.
