How to Setup Radiomaster TX16S Radio First Time

This tutorial walks you through how to setup the Radiomaster TX16S radio. I will try to explain everything you need to know how to use the TX16S for the first time, including battery, radio settings, model setup and gimbal calibrations.

Here is my review of the Radiomaster TX16S, you can get it from https://bit.ly/34FLB2Y.

The TX16S and T16 are actually very similar, you can follow this guide to setup both radios.

Installing Battery

There are several battery options for the TX16S. The most common being two 18650 cells, and that’s what I personally use. The radio comes with a 18650 battery holder, so it’s pretty much plug and play.

18650 battery are not included so you have to get your own. I personally use Panasonic NCR18650B 3400mAh because they performed the best in my test.

There are other options thanks to TX16S’s large battery compartment:

To turn on the Radiomaster TX16S, simply hold down the power button in the center of the radio for a few seconds.

Startup Warnings and Why

Brand new radios shouldn’t give you any warning when you first turn it on, but in case you do, here’s a list of possible warnings and how to fix them.

  • Throttle Warning – your throttle stick is not at the lowest position when the radio is turned on. Simply move the throttle stick all the way down will get rid of this warning
  • Switch Warning (aka Control Warning) – some of the switches are not in their default positions. Simply put all the switches to their UP position to remove this warning
  • Failsafe Not Set – Go to “Model Setup” (press MDL button), scroll down and find “Failsafe”, set it to No Pulse
  • Alarms Warning – This warning will appear if Sound mode is set to mute
  • SD Card Warning – SD card content version does not match the firmware version. If you get this warning, follow this guide to fix it

If everything goes well, you should get to the default home page, which should look something like this.

Radio Setup

Hold down the “SYS” button (top left) for 2 seconds to access the Radio Setup Page.

The things to change right now are:

  • Date & Time
  • Battery meter range (for 18650, 6.0 – 8.4V, for 2S LiPo, set 7.0 – 8.4V)
  • Alarms
    • Battery low => for 18650, 6.6V, for 2S LiPo 7.4V
    • Inactivity => 10m (if the radio is untouched for 10 minutes, it starts beeping)
    • Sound off => Disabled
    • Check RSSI on shutdown => Enabled
  • Backlight
    • Mode => Keys (only menu buttons would activate backlight, sticks and switches won’t, this saves battery as you don’t need backlight while flying)
    • Duration => 15s (backlight stays lit for 15 seconds)
    • OFF brightness set to lowest to save battery
    • Alarm => Enabled (backlight turns on when there’s a warning on the radio)
  • Pwr Off delay – the time it takes to hold down the power button to switch off the radio, this is basically a safety feature to avoid accidentally turning the radio off. I personally set it to 1s for faster shut down, but if you want to play safe just leave it at default (2s)
  • USB mode – set it to ASK
  • (Optional) lower haptic strength and length, default was a bit too strong
  • (Optional) set Sound to “All” so you get the “beeps” when scrolling

Here’s my whole radio setup:

To exit and go back to the main screen, just press the “RTN” button.

Calibrating Gimbals and Sliders

Go to Radio Setup page again, then press “PAGE” button a few times to go to “HARDWARE” page, select “Calibration” option to calibrate the sticks and sliders. Just follow the instruction, it’s pretty straight forward.

The gimbal stick calibration interface looks like this:

Make sure you only move the sticks as shown in the following image. For best result, do not move the sticks in circle.

Calibrate Battery Voltage

To ensure accurate battery voltage reading, you should calibrate the radio’s battery voltage.

Remove the battery from the radio, and check voltage with a voltage checker, or a digital multimeter.

Put the battery back in the radio, go to the “Hardware” page (hold SYS button and press PAGE button), scroll down to Battery Calibration and verify if the readings are the same. You can adjust it with the roller wheel button.

Creating Models

Although you can transfer models between OpenTX radios, but I highly recommend creating model profiles from scratch to avoid any conflicts and incompatibility issues. Once you created one model, you can use that as a template and just duplicate it for your other models, so it’s really not that hard.

Pro Tip:

Some people prefer to create a new profile for every single drone they have. But if you have a dozen of models like I do, it becomes a lot of work, and it’s hard to manage.

So what I personally do is only create a model profile for each RF protocol, and I bind all my quads that use the same protocol to that profile. For example, I only have four profiles, and they are for Frsky D8, D16, Crossfire and FPV simulators.

The other benefit with this method is consistency, as all your quads would have exactly the same radio configurations.

To create a new model, first go to the “Models” page by holding down the roller button for 2 seconds from the home screen, then select “Model Select” option.

Here you can view all the model profiles you’ve created. You can do a number of things by holding down the roller button.

Creating Model Profile From Scratch

To create a new model profile for quadcopter, go to the “Models” page (hold down the roller button, and choose Model Select).

In Models page, hold down the roller button again and select “Create Model” option.

Here you can choose a model template based on the type of aircraft, but currently there are still no multirotor, only glider and plane available. Don’t worry, we can work around this, hopefully the missing multirotor template will be added in future OpenTX firmware update.

For now, to create a model from multirotor, just select “Plane“, and then go through the following steps (press PAGE button to move onto the next step)

  • “Does your model have a motor?” Yes
  • “What channel is it on?” CH3
  • “Number of ailerons on your model?” One, or two with Y cable
  • CH1 (A)
  • “Does your model have flaps?” No
  • “Pick the tail config of your model” One channel for Elevator and one for Rudder
  • CH2 (A), CH4 (B)

Once you have created the model, you can also use it as the template for future quadcopter models. Simply duplicate this model instead of creating a new one, but note that it will also copy all the model settings.

Creating Model for Fixed Wings

For fixed wings, the steps are exactly the same as a quadcopter model. However you do need to change the mixer settings as described here: https://oscarliang.com/taranis-mixer-for-wings/

Model Settings

After creating the profile, now is time to setup your model, such as the Model Name, RF module setting etc.

To access “Model Setup” page, press the “MDL” button from the main screen.

RF Module Setting for Frsky

  • Set External RF module to Off
  • Change Internal RF module to MULT, Change sub mode to the protocol of your choice

For example, for Frsky 2.4GHz receivers, like the R-XSR and XSR, choose Frsky and D16. Some tiny whoops might require D8.

Note: you can’t change channel range to “Ch1 to Ch8” for lower latency, the only option is “Ch1 to Ch16”. I think this might be a bug and hopefully will get fixed in the future.

Don’t forget to set Failsafe method to “No Pulse” (this is your choice, see why I choose no pulse here)

Finally, you should fine tune RF Frequency to optimize range. This is only needed when using the internal Multi-protocol module.

RF Module Settings for Crossfire

Crossfire is a popular long range radio system. Once you’ve installed the Crossfire module in the module bay of the TX16S, you can enable it by:

  • Set Internal RF module to Off
  • Change External RF Mode to CRSF

There are more settings related to Crossfire in the Crossfire Configure Tool (hold down the SYS button), including Failsafe and Frequency.

Create Switches

Switches are not setup out of the box, they can be used for arming the quadcopter, activating beeper etc.

Enter Model Setup page, then go to the Mixer page by pressing the PAGE button a number of times.

In here, create a new mix on CH5, under “Source”, select the switch you’d like to use (Pro tip: just flip the desired switch, it will automatically appear).

Repeat the same steps on the following channels (e.g. Ch6, Ch7 and Ch8) and add more switches and sliders. There are 16 channels available for SBUS (Frsky D16) and Crossfire, minus the 4 channels used for the sticks, you have a total 12 channels you can use to assign to switches, knobs and sliders.

Can’t figure it out? Here is a more detailed step by step guide.

Duplicate Model Profiles

If your models have more or less the same configurations, you can simply duplicate your the model you’ve just created.

Personally, I don’t create profiles for different models, that’s a lot of work if you have a bunch of drones. I create profiles only for different RF protocols. For example, I have one profile for Frsky D16, one for Frsky D8, and another for Crossfire. Each profile is bound to multiple models that are using that RF protocol.

It’s totally up to you how you manage your model profiles by the way, there is no wrong or right way :)

Create Model for FPV Sims

Duplicate from one of your quadcopter models, and set both internal RF and external RF to off. you don’t need to use RF module when flying FPV simulators via USB cable, this will save battery and keeps your RF module cool :)

Adjust Gimbal Tension

The TX16S offers gimbal adjustments at the back of the radio. By removing the back rubber panels, you can access the screws through the holes to change the stick spring tension.

However I personally find it difficult to do as I can barely see those screws.

So I normally just take the radio apart. You can find out how to do this in my review. And here are the screws responsible for the gimbal stick tension.

Updating Firmware

You don’t have to update firmware, unless there is a bug with your current version, or the new firmware offers a feature you really want. You can follow this guide to flash OpenTX to the TX16S and T16.

Beware that flashing new firmware might reset radio settings, and it’s best if you backup your models before doing so in case something goes wrong.

    Any idea why my crossfire module won’t come on when connected to radiomaster? Works fine with spektrum tx but nothing through the Jr bay.

      Did you enable “external RF” and set it to Crossfire in model setup page? If this is set to off Module bay will not be powered.

    I don’t know if anyone else has this issue but on my radiomaster TX16S when I set it to frsky d8 there is no fail safe option whatsoever. On d16 it’s there but I can’t seem to get it to come up on d8. Not sure if this is normal or not.

      Hold down the MDL for 2 seconds, is it not responding? Maybe the button got stuck inside. You might be able to fix it yourself but if you are not confident in doing that, contact your reseller.

    Hi Oscar thanks for all your informative advice. I have a jumper t16 pro and have downloaded free rider and fpv air2 to my pc windows 10. The simulators won’t see the jumper when it’s plugged into the pc with the supplied cable. I watched a video that said in device manager you have to change the USB device to get rid of BETTER_USB_HS but when I try to update it it won’t let me and says Windows has determined that better USB HS is the best driver for this device. When I plug the jumper in it does make a beep on the pc and shows USB icon in the jumper screen. Or is there anything on the jumper I need to set up to make it work with a simulator. Many thanks.

    My Turnigy Evolution gimbals were starting to get sloppy and I was ready to upgrade to a big-boy transmitter. The Jumper T16 Pro got great reviews and support for multiple protocols sealed the deal.

    Using the Evolution, I had TGY-i6AC (FS-i6AC) receivers in my builds. I was surprised there was very little T16/OpenTX set up information for this receiver. The standard No Pulses Failsafe did not work with the iA6C.

    Protocol: FSky 2A on the T16 model setup,
    Type: Flysky AFHDS2A, Subtype: PWM and IBUS in OpenTX Companion

    Failsafe: Custom/Set on the T16 model setup, CH3 (throttle) -100, CH5 (Failsafe) -100
    Custom/Failsafe Positions, 3 value -100, 5 value -100 in OpenTX Companion

    Getting a solid connection from transmitter to the i6AC receiver is a little wonky. I usually takes a couple of tries to get a full 5 bar connection, but once it connects with that full 5 bar connection is stays connected.

    Oscar.. Your posts have been so informative.. I was an original purchaser for the t12.. im feeling a bit left out by JUMPERTX.. am i forever stuck on JUMPERtx Fork? i see many running the new OPENTX and i cannot for the life of me get the firmware to push.. I get errors and Wrong firmware msgs.. i have the companion.. it says to upgrade yadayda i can read my radio and model profiles copy them etc.. but cannot push the new openTX to it.. :( any suggestions would be beneficial.. I have spent more time tinkering with firmwares etc then flying and it is starting to bum me out.. I have both the 4in1 and R9 mods.. kind of a pain to have to flash a FLEX firmware just to run the r9 and standard for the 4in1.. plus cant get true OPENTX this has become a logistics nightmare.. even when i get a new receiver.. i have to reflash everything.. it really is not fun I just want to program and fly..

    Hi Oscar!

    You say: “Alarms => Battery low => for 18650, 6.6V, for 2S LiPo 7.4V” . But the minimum voltage in specs for T16 pro is 7.0V. Why set battery alarm below min voltage? Or what is the min alarm voltage I can safely set? Can I go even lower than 6.6V, if my 18650 batteries allow so? Thanks!

    the T16 Pro 18650 battery holder does not accommodate protected batteries. It’s easy enough to remove the protection circuit if you bought the wrong ones (like I did).

    Hi Oscar,
    first of all, thank you very much! I learned a lot about how to fpv from you!
    Coming from heli, microquads and whoops are now my thing. To be able to
    fly almost anywhere is untoppable:) Two months ago i sold my dx8 and got
    myself a T16. I should have switched years ago as opentx is just what i ever
    wanted, and probably all i´ll ever need…Now my question: I got myself the
    orignal T16 and would like to for an internal module. I heard that this is possible
    now. Is this the same as the external jp4in1? Is there anything important to know
    switching to internal?

    Thx
    Lars

      No, it’s completely different board, but they work the same, except the internal RF module free up the external bay.
      I think it’s not necessary, unless you frequently use other external modules like the Crossfire. Otherwise if you only use the multi-protocol module, there is no point of doing it.

    I just got my T16 Pro, and followed these instructions. Things seem to work, except that I get a ‘Minimum Trim Reached’ warning whenever I move the left rear pot above mid level. It appears that the pot is working ok – the indicator for it moves properly all the way from top to bottom as I move it. But I keep getting this warning. I got the warning when I first turned on the radio, I got it as I moved the left pot during calibration, and now I get it whenever I move the left pot above mid level. Any idea why this would be? Why would the left pot be connected to a trim warning?

    1. Oscar Post author

      Check if there is a global function doing that? (long press menu, and press page until you arrive at global function)
      Also try creating a new model from scratch and see if you still get that?

        Thanks. You’re second suggestion was on the money – this does not happen with new models. It just seems to be something that someone did with the ‘Model 01’ that was initially on the transmitter. Somehow the left back pot had been assigned to trim something (I didn’t actually figure out what), and was exceeding the range of available trim. Anyway, since it was just a glitch in this (unneeded) model, it does not represent a real problem. I have a couple of models working now, and am proceeding to figure out how do more things with the T16.

    Hello. I just got a t16 pro. After trying to add a new model from open tx, when I disconnect the usb cable I get a storage warning bad radio data on the screen. The new model is not added to the radio. Any ideas?

    Reply
    1. Ken Leedham

      I think this is again the problem with transferring in a model set to use internal radio module. Apparently that results in ‘Bad Storage’ and ‘Emergency Mode’ message, and the T16 basically just stops functioning properly. Hopefully this will be (is?) fixed in later firmware. I believe the fix would be to reinitialize the T16 with default files on the SD, and then avoid transferring in any models set to use internal radio.

    Do you think it is a bad/defective switch?

    I’ve been flying with the Taranis XD9 Plus for many years and love it but this Jumper with it’s scroll wheel and splashy colorful screen really caught my eye…

    I’ve had the Jumper module for the Taranis for some time as well..

      sounds like a defective switch to me. can you confirm the switch is working? You might be able to fix it quite easily instead of asking for replacement, just check the soldering or replace the switch. They only cost a couple of dollars.
