Bill describes how he does this using Companion.

How to move models over from different OpenTX transmitters to the T16.

Bill describes how to use OpenTX Companion to set up Expo.

Bill demonstrates how to add some widgets to the main screen using the Tele button. He notes that you can put in the rudder value, but that can be changed to anything with a value by scrolling. He only covers a few of the possible options. He does not cover the four top widgets or even how to get to them.

There is no voice description, but words on the screen during the video. The information goes by quickly in real time, but can paused at any time. The background music is totally irritating.

He uses the create model wizard to set up a plane, but does not show the other options for each selection. He also goes through each screen to get all of the data entered for the model that he's creating. As with all things OpenTX, this is only one way of doing the programming that he's showing. There are other ways to do it, and some may be simpler than this method.

This method might help when using ESCs that will arm when the throttle is advanced. Most of today's ESCs won't arm until the throttle is in its lowest position, but some still do.

He shows how he creates a file to say "Flip Mode Off". He's not sure how many characters the final wave file for the T16 can be. I checked and found eight characters to be the maximum for the file name. I also observed no uppercase letters in the file names, but digits seem to be okay.

Liftoff: FPV Drone Racing Simulator is from a company called Steam and costs $19.99. Bill demonstrates how he set up the JumperT16 to use this simulator.
He used the Setup Wizard and I noticed that his icon for Plane is on the left, like mine, yet all of the other Setup Wizards that I've seen online display Plane on the right.
Near the beginning of the video below this one, the Glider icon can be seen on the left and Plane icon on the right. That appears to be the most common way, and the fact that OpenTX appears to randomly place the icons bothers me.

Appears to be in Korean and not translated, but the sound can be turned off and simply watching should show how to set up a Helicopter. Includes: Create Model, Model Name Setup, Timer Setup, Flight Mode Setup, Create Pitch Channel, Throttle Hold Setup, Make Curves, Attach Curves, Gyro Setup, Channel Reverse and Channel Monitor.

Bill demonstrates how to set up a XYMA X5C-1 quad.

He uses OpenTX Companion and a FrSky Tranis X-Lite to demonstrate the process, which he says would be the same with the Jumper T16. He says that all the binding would be lost using this process. He did a poor job of copying and pasting. Looks like he'd not practiced it.

A short video on preparing model images for use on the Jumper T16. His sizing recommendation, 155 x 100 pixels, is very different from TMac FPV's recommendation in the chart below. I have been using TMac's sizing of 192 pixels x 114 pixels. (I confirmed that size, 192 x 114 this morning. KM)

Shows how to set up flaperons in this poorly produced and thought out video, but he finally does it.

Demonstrates how to put the files and folders on the SD card and add the Amber sound pack.

Very short video demonstrates how to display the transmitter's battery in a top widget.

This is part 2 of his helicopter set up. Part 1 is Here

Video, with no sound, showing how to set up Elevons.

He demonstrates how to add a transmitter battery voltage and transmitter voltage gauge to the top widget bar. He also notes how to set the voltage range for the transmitter battery and how to calibrate the actual battery voltage.

Unfortunately, he does not use a good method to determine the actual voltage after the charge. All batteries will be at a higher voltage after a charge. The batteries should be allowed to set a few hours before measuring with a voltage meter.

He shows how to do it and uses his momentary switch at the top right of the transmitter, but it could be any switch.
I'm not sure why he put it on a switch. Holding down the Enter key brings up a menu with Reset in it for all of the timers, but that is how he chose to do it.
The timer also resets when the transmitter is turned off.

There is no sound, but the technique is clear.

This is about how to set up a model using OpenTX Companion. He notes that he's now using OpenTX 2.3.4.

Shows how to totally dim the backlight "almost" off. Similar to above.

How to set the various types of failsafe and when to use them. This is NOT Jumper T16 specific. I disagree with him about the receiver option. I think it should be used.

They started with setting up a model and did not show the stick calibration and other Tx setup. The transmitter needs to be set up first!
First they set up a model in the Tx. Bind to receiver. They cover how to do triple rates on ailerons. They set the failsafe selection to receiver. They show how to get rid of the failsafe not set warning when turn on the Tx. Show 5th channel for retracts and then how to discover sensors. They show how to get Tx to "announce" RSSI when switch is moved.
When setting up the failsafe they note putting that the throttle cut should be off, but they never set up the throttle cut.

Some key concepts are discussed and described here. Some of the information only applies to multi-rotors. It is a good video to get an overall understanding, in some ways.

From the video it looks like I can put the throttle cutoff on one of the 6 position switch buttons, which might be handy, which I actually did. I think he goes about this in a very roundabout way.

A quick how-to for OpenTX to get Audible feedback on center-positions.

Not sure this is at all useful for planes, except it talks about the Jumper R1 receiver for drones.

Global variables can be used to set up a variable Expo and Dual Rates as well as the Throttle Cut I'm considering.

By using two timers you can have one as a throttle timer and one as a count down timer. That could be useful. Shows how to do it, well not really. Moves onto how to set up a three position switch to the momentary switch so the the position of the 3-position switch determines the function on the plane. Finally shows how to do the countdown timer 2. In his example both stop when the throttle is shut down. To be useful, the count-down timer should continue, or vice versa.

Shows flaperon setup on transmitter and how it works on the plane.

This video demonstrates assigning names to the inputs. He notes that the side switches are useless as can easily be moved while flying.

Logs are stored in Logs in xls type file format. Add sensors. They are actually .csv format.

This is similar to a video I've seen on this topic. Uses rotary switch instead of 3 position switch.

Uses same control knob as Josh Bardwell. He doesn't appear to be adding as a global/universal value, which I think it should be. He uses a special function (SF) using the SF screen. It appears to be global without using the global setup. Somewhat confusing.

This method might be handy for controlling the volume, not what he's doing.

How to do it without buzzers, etc. using just the light on the receiver.

How to do this for retracts and flaps.

How to do it. How to do it for planes starts at 7:23 in the video. Drag timeline to that point. This sets up the throttle cut for a specific plane. My question is can it be set up as a global function? NO, it can't.

How to do it.

Can be used to set up Widgets across the top of the screen.

More on making custom model images. Title screen is wrong. This is for Jumper T16. TMac notes the actual size which I posted above. Painless states the wrong size.

Josh's how to on a custom splash screen. He's using .png, as he should. Not one of his best videos. Link for reference only.

How to: add custom sounds. Includes adding Amber sound pack and creating custom sounds. Uses sound program Audacity.

How to set up and move through the menus. This ncludes fine tuning FrSky and Jumper receivers.

Step by step for adding images to the Jumper T16. This is a very good tutorial for customizing. He puts his SD card into SD card reader and then works on the computer. The start up splash screen and model images are found in the IMAGES folder. The THRMES folder/Default contains the background images.

He didn't explain what he did with the original splash screen. The new image was named Splash with a capital letter when he transferred it to the SD card but it is splash with no capital S after he creates it. He did rename the background image background with no capital b. He does rename the original background.png to OLD_background.png.

Shows how to change in the transmitter without using a new flash screen from the computer to SD card.
An RGB color picker with the codes is found here.

What title says.

How to turn the module to the receiver. IMPORTANT STEP!

May or may not be a good idea. Guy mumbles through it.

Josh's step by step. Comes up with the glider and plane selection that I noted before. Don't make a model for each plane, make it for each protocol you'll be using. Then you can copy and rename it for each plane if you want to (my idea, not his).

Demonstrates how to set up extended limits.

How to program the 6 buttons for flight mode, but might be useful for something else with fixed wing.

Setting up FrSky Telemetry

Demonstrates stick calibration with no audio.

I didn't find this short video helpful, but maybe it will be to some helicopter fliers. This is part 1 of 2.

How to change switch assignments easily.

This is done using an early iteration of the T16. Navigation and setup hints and tricks. Still using external module. Very complete with what the buttons do followed by examples of how to set up a plane-type; glider or Plane. Good tips. Create a basic model and then duplicate when creating a new model.

Explains how to change background screen and more, with sizes and in what folders they are located on the the SD card. Didn't mention renaming originals to keep them if a change is made. He says that they have to be a .png, but I'm thinking, since I've seen it before that a .jpg would work, or maybe even .bmp. I don't know for sure now. Background image is the same size as the splash screen, 480x272. Model images are 192x114. The splash screen is in the Images folder on the SD card ans is called splash.png. The background image is in the Themes folder. It is named background.png. Model images go in the IMAGES folder.

Follow the first about 5 minutes of this video to set up the transmitter. A better calibration video follows this video.
The date and the red T16 sticker indicate this is an early version of the T16. He sets stick lengths to his preference. Next he shows the stick calibration. He notes that there is NOT a strong detent on side sliders. He also notes that you should NOT push too hard at the edges when calibrating. Don't forget to do the top six buttons. He did not recenter the right slider before finishing the calibration.
He demonstrates how to assign volume control to a knob.
He notes that OpenTX Companion needs to be downloaded and he tells from where, but the version of OpenTX he refers to is NOT for the Jumper T16. He transfers models, but he seems very, very confused about what he's doing. Next he sets up the home screen.

He shows how to get telemetry setup for iNav, for multi-rotor, but might be useful for later telemetry info.

Describes the buttons. Shows how to calibrate sticks. He didn't move the sliders and knobs switched back to center. Shows basic model setup. Note knowledgeable about the topic at all. Link for reference only.

This applies to ANY OpenTx transmitter, although the Taranis is used for the example. Shows how to set up as a Global function to apply to all models.

Good video to start with to get thinking about model setup programming using OpenTX. Not a Jumper specific video.
