New OpenTx Radio? You Should Perform All Three of These Calibrations Radiomaster TX16s Calibrate

My 6-position switch is the same, -100 -60 -20 19 59 99. Thanks for confirming that mystery!

[@RCVideoReviews]

Weird isn't it? I never found out why that happens.

[@SBWings]

@@RCVideoReviews After experimenting with some logic switches, I've come to the conclusion that it's a hardware issue with the 6P encoding chip. In the 6th position, where variable 'a' should equal 100, I got the following results: a>99 is true; a=100 is false; a

[@WatsitTooyah]

Yes my 6 position switches are the same for radiomaster tx16s. At least its consistent. You can set functions to match with a small range so I still use ~20, ~60 and ~100 for this switch.

[@RCVideoReviews]

I just ran a little experiment and set the 6p up as an input and assigned it a channel so I could see the values in channel monitor. In channel monitor I get -100, -60, -20, 20, 60, 100 So it seems something in their calibration scale is off.

[@WatsitTooyah]

@@RCVideoReviews Oh wow. thanks for info.

[@paulbharper6612]

Yes my six position is reading just like yours and I just bought my tx16s max one month ago so a year later they are still reading the same

[@lasersbee]

1:30 ... I had measured the current draw of the TX16S and it was 250mA to 350mA depending on which protocol you choose or if the Screen is at High output or Standby. The radio only powers either the Internal or External modules at a time.

[@RCVideoReviews]

So .1c is a good estimate for discharge rate. I knew you did this kind of work and hoped you'd chime in. Thx!

[@lasersbee]

@@RCVideoReviews Yeah for a 3200mAh Battery it would be closer to the 1c curve. I use a RadioMaster 5000mAh battery. I still need to do a Discharge /Charge test to see it's actual real world capacity.

[@RCVideoReviews]

@@lasersbee Wait: 3400mah = 3.4a = 1c So .1c = .34a = 350ma right? So the .1c curve, not 1c curve. 1c would be 3.4a.

[@lasersbee]

@@RCVideoReviews Yeah you are correct 0.1C...Brain Fart...;-) At 3.2 V per cell that would be the cutoff point. The Rated Capacity of a battery in mAh would depict the run time before a charge would be needed. In your case of 3400mAh cells about 9.7 hours non stop at a constant current drain of 350mA.

[@DontEverGrowUp]

I suspect the 6-position switch is merely equally divided. -100 to -1 is 100 steps, as is 0 to 99. It's probably just due to the math OpenTX is doing. Also, somehow I missed how you get to this Analogs Test screen.

Same here, 99 and not 100 on the 6 position switch. Just live with it I think.

[@RCVideoReviews]

Yeah, I think so. As long as the switch works I don't see an issue. If this were a control surface I would have a complaint.

[@bohan9957]

I'm also getting 99 at the 6th flight mode button. If you didn't point this out I wouldn't have noticed it. It must be software related, since all these appear to be consistent at 99. One thing I still haven't figured out is if there is a way to change the clock from 24-hour based to 12-hour based with an AM/PM indication.

[@RCVideoReviews]

Doesn't look like there's an option to do that. I've never looked for one because I prefer the 24h clock. But a little googling around shows the OTX devs don't want to do it because it would require overhaul of the gui and it would break a lot of LUA scripts. Thanks for the feedback on your 6p switch.

[@kglas]

These vids on the TX16s are incredibly helpful, especially for total newbies like me. I've bought a Mode 1, but realised 2 would be better (just personal choice). There is a vid from Radiomaster on changing over the gimbals, but it shows a completely wire free back cover. For some reason I have a few wires attached to inside of mine. Any chance of putting up a video of swopping Modes over ?

The wires are probably for the back cover speaker. They added that in a mid-cycle product update. I've been thinking of doing a gimbal mode change video for a while now. Isn't the Radiomaster video on the subject helpful?

Run the calibration again. It should read 0 when you're done.

[@witneydiggersrc3251]

Brilliant video, thanks. How often would you calibrate? Why do you sometimes see flickering when, for example, the slide calibration is moved to the neutral point?

[@RCVideoReviews]

We just talked about this on discord. It never hurts to calibrate and it only takes a minute. That said, unless you physically change something about your hardware, it's not necessary after the first calibration. Don't worry to much about minor variances in potentiometers as there is a lot of math between the analog input and RF output. Watch your channel monitor outputs. If they aren't moving without input, then your model won't move without inputs either.

[@witneydiggersrc3251]

Brilliant channel. 👍

I get exactly the same numbers on mt TX16S, so I think it's Open TX firmware related.

Thanks for reporting back. On the Livestream tonight I showed how even with the 1pt offset it still outputs -100, -60, -20, 20, 60, 100. So it seems to be a calibration output bug. Doesn't seem worth worrying about.

This question came up in Discord and I asked Radiomaster. Their answer: "It means either the battery is not installed or there is a problem with the pack or its connectors OR The USB PSU is struggling." And "One other possibility: Check the cell health of the battery (check the IR). One of the cells could be lagging and the other going over so the good cell is going over 4.2 so it is stopping the charge to avoid going past 4.2v on the good cell"

John: I am a recent subscriber, as well as currently awaiting my registration email to join RCmodelreviews.com, as you've become an invaluable resource for me, being the proud new parent of a jumper t18! I chose this model in part based on the misleading description of the IPS screen having an upcoming feature of being a touch screen. I refer to this as misleading, because should this feature be supported in an update, we will need to purchase and install the digitizer ourselves, or have it installed. Had I known this at the time of purchase, I probably would have bitten bullet and purchased one of the more expensive RadioMaster models, however, I'm not finding the lack of touch as the deal breaker that I initially thought it might have been. Like many open source products, I'm overwhelmed by the potential of the device & software, and the learning curve is a painful process in my old age (46) but most definitely seems worthwhile, the cost savings alone over a Spektrum product with high channel count and half the features is staggering! I hope you'll be doing another live OpenTX class soon and I very much intend on donating via Patreon which I'll consider 'Tuition' for my education. Just waiting for my next paycheck! I did have one bad experience, scared the crap out of me, only had my tx a couple of days when I saw your video about the 3 calibrations one should do upon acquisition of a new tx, I had begun the battery calibration and when I touched the contacts from my my multimeter to the exposed battery contacts, smoke emitted from the tx & she went black! "OH SHIT!" I exclaimed as I disconnected everything, including the battery from the radio and when I plugged back in, nothing happened! I was starting to despair when I tried another battery and it worked fine, and it turned out that the battery had slid from the contact inside the battery holder. I haven't fainted this idea what caused this, though I'm certain I'd done something wrong, but, wow, I really thought I killed it! If I can figure out what stupid mistake I made to cause this I will update this message so that others can be warned and avoid my mistake.
