Have you checked the voltage with another tester, like a digital volt meter, etc.?  A battery checker is ok, but most are cheaply made and to have a .1 volt variance at 16 volts is likely.     And frankly if you are at 16.7 vs 16.8, it's not a big deal if you are flying freestyle....if you're racing or flying long range, then every fraction of a volt might be important.  But really in the end .1 volt is not a big deal.  

And like Snow mentions, make sure you are balance charging.

If you have a calibrate DMM to check against, it will let you know if your charger is correct or not.

Yes, I'm balance charging. I'm using my digital volt meter for testing from work so I know it works. If you guys say 16.7 is a good full/resting charge then that's good enough for me.

Okay, I want to hook up to BetaFlight tomorrow, but I do not have a smoke stopper yet. I've checked all my solder connections for continuity/crosses and everything checks out. Is there something else I need to check before firing it up, or should I just wait? If I wait I guess I can test the discharge/storage setting on my charger.

You should be able to connect to Betaflight just using the USB cable. It will provide enough juice for the FC to power up and allow you to access the Betaflight. Of course you can't set up everything as I guess your VTX and RX won't be powered (some FCs do pass the 5V from the USB to the 5V pads - like some cheap Omnibus clone from Banggood I have, so if you power your VTX and RX from 5V pads on the board, it might work). But to check that you can connect to BF, the gyro is working, orientation is correct etc., USB connection only should be fine.

You probably know this already, but if you're going to hook up a battery make sure your video antenna is on or you can burn out your VTX!

Next questions:

Is the R-XSR compatible with the FrSky R9M? I guessing no, but I have no idea. The building of the quad is easy once you know where everything goes as I'm a hands on type of guy. This matching/mating/flashing/compatible parts thing is killing me. Not a tech guy.

Does the R9M need an external battery? I'd like to use the module since it came with the radio. But I have the R-XSR and I can't find anything that answers my question. I figure the pros here can.

I'm so close, but all the technical stuff is starting to wear on me....

Deal

p.s. I don't even know where to begin. BetaFlight and setup the quad, pairing of the radio to the receiver, pairing the goggles to the quad.... The list seems to go on and on. Hopefully it gets easier after the first time....

The short answer is no.

R-XSR runs on 2.4 ghz. 2.4ghz is the built-in radio module for your Frsky radio. If you want to use the R9M module, you will need a R9M compatible receiver like the R9MM receiver. R9M runs over 900mhz frequency. Gives you long range control. Similar to Crossfire system from TBS.

No external battery for R9M.

Watch Joshua Bardwell series for beginners. It will answer a lot of questions. Come back when you get stuck.

Thank you sir. That's what I thought. Parts for the future. I'll ditch the R9M for now.

Deal

900mhz has been around. People are just getting into it now. Kind of like 2.4ghz VTX. As more people go to 900mhz, you will probably see more of them going to 2.4ghz video.

Okay. I've watched countless videos and now I turn to you guys.

I'm not getting any stick movements on Betaflight. According to the LED's on the receiver it is bound to my radio. Betaflight does see the quad though because it moves when you move it.

Every time I save and reboot it erases my uart and my receiver selection under configuration. Am I not picking the right uart? If so, how do I find out? Did I miss something on my Taranis setup?

I have so many questions....

That happened to me some time ago, and it was that I was using the chrome app of the betaflight configurator instead of downloading the last version of the betaflight configurator from here
https://github.com/betaflight/betaflight...tag/10.4.0

I'm using the latest.

Deal

The only time I experience things resetting in BetaFlight is when I gets things mixed up on the PORTS page.

So working in just the PORTS tab, if the port is set to SerialRX with the correct UART assigned (leaving the CONFIG tab alone for the moment) and you reboot your FC through BF, it reverts the port assignment back to vanilla?

I had to leave the house. I've done it so many times so many ways I can't remember. I'll redo that when I get back.

Can you please run the "dump" and also the "diff all" commands in the CLI and post the results back here just in case there is something obvious that stands out in your configuration that might be causing this.
