How to Setup Radiomaster TX16S Radio First Time

This tutorial walks you thru tips on how to setup the Radiomaster TX16S radio. I’ll attempt to clarify all the things it’s worthwhile to know tips on how to use the TX16S for the primary time, together with battery, radio settings, mannequin setup and gimbal calibrations.

Here is my review of the Radiomaster TX16S, you will get it from

The TX16S and T16 are literally very related, you’ll be able to observe this information to setup each radios.

There are a number of battery choices for the TX16S. The most typical being two 18650 cells, and that’s what I personally use. The radio comes with a 18650 battery holder, so it’s just about plug and play.

18650 battery aren’t included so you must get your personal. I personally use Panasonic NCR18650B 3400mAh as a result of they performed the best in my test.

There are different choices due to TX16S’s giant battery compartment:

To activate the Radiomaster TX16S, merely maintain down the facility button within the middle of the radio for a number of seconds.

Brand new radios shouldn’t offer you any warning while you first flip it on, however in case you do, right here’s a listing of attainable warnings and tips on how to repair them.

  • Throttle Warning – your throttle stick shouldn’t be on the lowest place when the radio is turned on. Simply transfer the throttle stick all the best way down will eliminate this warning
  • Switch Warning (aka Control Warning) – a number of the switches aren’t of their default positions. Simply put all of the switches to their UP place to take away this warning
  • Failsafe Not Set – Go to “Model Setup” (press MDL button), scroll down and discover “Failsafe”, set it to No Pulse
  • Alarms Warning – This warning will seem if Sound mode is ready to mute
  • SD Card Warning – SD card content material model doesn’t match the firmware model. If you get this warning, follow this guide to fix it

If all the things goes effectively, it is best to get to the default residence web page, which ought to look one thing like this.

Hold down the “SYS” button (high left) for two seconds to entry the Radio Setup Page.

The issues to alter proper now are:

  • Date & Time
  • Battery meter vary (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 begins beeping)
    • Sound off => Disabled
    • Check RSSI on shutdown => Enabled
  • Backlight
    • Mode => Keys (solely menu buttons would activate backlight, sticks and switches received’t, this protects battery as you don’t want backlight whereas flying)
    • Duration => 15s (backlight stays lit for 15 seconds)
    • OFF brightness set to lowest to avoid wasting battery
    • Alarm => Enabled (backlight activates when there’s a warning on the radio)
  • Pwr Off delay – the time it takes to carry down the facility button to modify off the radio, that is mainly a security characteristic to keep away from by chance turning the radio off. I personally set it to 1s for sooner shut down, however if you wish to play secure simply depart it at default (2s)
  • USB mode – set it to ASK
  • (Optional) decrease haptic energy and size, default was a bit too sturdy
  • (Optional) set Sound to “All” so that you get the “beeps” when scrolling

Here’s my complete radio setup:

To exit and return to the principle display screen, simply press the “RTN” button.

Go to Radio Setup web page once more, then press “PAGE” button a number of occasions to go to “HARDWARE” web page, choose “Calibration” choice to calibrate the sticks and sliders. Just observe the instruction, it’s fairly straight ahead.

The gimbal stick calibration interface appears to be like like this:

Make certain you solely transfer the sticks as proven within the following picture. For greatest consequence, don’t transfer the sticks in circle.

To guarantee correct battery voltage studying, it is best to calibrate the radio’s battery voltage.

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

Put the battery again within the radio, go to the “Hardware” web page (maintain SYS button and press PAGE button), scroll right down to Battery Calibration and confirm if the readings are the identical. You can modify it with the curler wheel button.

Although you can transfer models between OpenTX radios, however I extremely advocate creating mannequin profiles from scratch to keep away from any conflicts and incompatibility points. Once you created one mannequin, you should utilize that as a template and simply duplicate it to your different fashions, so it’s actually not that tough.

Pro Tip:

Some folks want to create a brand new profile for each single drone they’ve. But you probably have a dozen of fashions like I do, it turns into plenty of work, and it’s arduous to handle.

So what I personally do is simply create a mannequin profile for every RF protocol, and I bind all my quads that use the identical protocol to that profile. For instance, I solely have 4 profiles, and they’re for Frsky D8, D16, Crossfire and FPV simulators.

The different profit with this methodology is consistency, as all of your quads would have precisely the identical radio configurations.

To create a brand new mannequin, first go to the “Models” web page by holding down the curler button for two seconds from the house display screen, then choose “Model Select” possibility.

Here you’ll be able to view all of the mannequin profiles you’ve created. You can do plenty of issues by holding down the curler button.

Creating Model Profile From Scratch

To create a brand new mannequin profile for quadcopter, go to the “Models” web page (maintain down the curler button, and select Model Select).

In Models web page, maintain down the curler button once more and choose “Create Model” possibility.

Here you’ll be able to select a mannequin template primarily based on the kind of plane, however presently there are nonetheless no multirotor, solely glider and aircraft out there. Don’t fear, we will work round this, hopefully the lacking multirotor template will probably be added in future OpenTX firmware replace.

For now, to create a mannequin from multirotor, simply choose “Plane“, after which undergo the next steps (press PAGE button to maneuver onto the subsequent step)

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

Once you could have created the mannequin, you can even use it because the template for future quadcopter fashions. Simply duplicate this mannequin as an alternative of making a brand new one, however observe that it’s going to additionally copy all of the mannequin settings.

Creating Model for Fixed Wings

For fastened wings, the steps are precisely the identical as a quadcopter mannequin. However you do want to alter the mixer settings as described right here:

After creating the profile, now could be time to setup your mannequin, such because the Model Name, RF module setting and so forth.

To entry “Model Setup” web page, press the “MDL” button from the principle display 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 selection

For instance, for Frsky 2.4GHz receivers, just like the R-XSR and XSR, select Frsky and D16. Some tiny whoops may require D8.

Note: you’ll be able to’t change channel vary to “Ch1 to Ch8” for lower latency, the one possibility is “Ch1 to Ch16”. I feel this is perhaps a bug and hopefully will get fastened sooner or later.

Don’t overlook to set Failsafe methodology to “No Pulse” (that is your selection, see why I choose no pulse here)

Finally, you should fine tune RF Frequency to optimize range. This is simply wanted when utilizing the interior Multi-protocol module.

RF Module Settings for Crossfire

Crossfire is a popular long range radio system. Once you’ve put in the Crossfire module within the module bay of the TX16S, you’ll be able to allow it by:

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

There are extra settings associated to Crossfire within the Crossfire Configure Tool (maintain down the SYS button), together with Failsafe and Frequency.

Create Switches

Switches aren’t setup out of the field, they can be utilized for arming the quadcopter, activating beeper and so forth.

Enter Model Setup web page, then go to the Mixer web page by urgent the PAGE button plenty of occasions.

In right here, create a brand new combine on CH5, beneath “Source”, choose the change you’d like to make use of (Pro tip: simply flip the specified change, it should mechanically seem).

Repeat the identical steps on the next channels (e.g. Ch6, Ch7 and Ch8) and add extra switches and sliders. There are 16 channels out there for SBUS (Frsky D16) and Crossfire, minus the 4 channels used for the sticks, you could have a complete 12 channels you should utilize to assign to switches, knobs and sliders.

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

If your fashions have roughly the identical configurations, you’ll be able to merely duplicate your the mannequin you’ve simply created.

Personally, I don’t create profiles for various fashions, that’s plenty of work you probably have a bunch of drones. I create profiles just for completely different RF protocols. For instance, I’ve one profile for Frsky D16, one for Frsky D8, and one other for Crossfire. Each profile is sure to a number of fashions which are utilizing that RF protocol.

It’s completely as much as you the way you handle your mannequin profiles by the best way, there isn’t a fallacious or proper manner 🙂

Duplicate from one in every of your quadcopter fashions, and set each inside RF and exterior RF to off. you don’t want to make use of RF module when flying FPV simulators by way of USB cable, this may save battery and retains your RF module cool 🙂

The TX16S gives gimbal changes in the back of the radio. By eradicating the again rubber panels, you’ll be able to entry the screws by the holes to alter the stick spring rigidity.

However I personally discover it troublesome to do as I can barely see these screws.

So I usually simply take the radio aside. You can find out how to do this in my review. And listed here are the screws accountable for the gimbal stick rigidity.

You don’t must replace firmware, until there’s a bug together with your present model, or the brand new firmware gives a characteristic you really need. You can observe this information to flash OpenTX to the TX16S and T16.

Beware that flashing new firmware may reset radio settings, and it’s greatest should you backup your models earlier than doing so in case one thing goes fallacious.

Custom Sound Pack

You can obtain customized sound pack and substitute the unique one. My favorite is Amber sound pack, the sound high quality is healthier than the unique.

Download right here:

Unzip and substitute the information within the SOUND/en folder on the SD card.

Playing Custom Sounds

You can play customized sound information in your TX16S. I’ve a tutorial on how to create custom sound file for OpenTX radios.  You may even play your favorite songs.

Make certain the filename doesn’t exceed 6 characters, and the file extension doesn’t exceed 3 characters, or the file received’t present. And it doesn’t like symbols within the filename both.

File format: 32000khz Mono Wav

Custom Interface Color and Layout

See my tutorial.

Model photos should be PNG file, filename 6 character max in a single phrase no area, no symbols. Put them within the picture folder within the SD card.

Splash display screen (startup display screen): 480×272 pixel, title it splash.png and place it within the picture folder within the SD card.

Assign Volume Control to Knob

I discovered it actually handy to have the ability to modify radio sound quantity utilizing one of many potentiometers (S1 or S2).

Go to Radio Setup Page once more, then press “PAGE” button a number of occasions to go to “Global perform” web page, and assign quantity management to a knob. You can even do it beneath mannequin setup, particular perform, however I want doing this in Global perform so it takes impact on all fashions.

Replacing Internal Button Cell Battery

If your radio stops saving settings equivalent to date and time, you in all probability want to exchange the button cell battery contained in the radio (or it’s lacking). You can purchase this fairly cheaply on-line.
