what Kilrah said... document1.otx is the format of data stored on your PC by Companion. model.bin is the format stored on your transmitter by your transmitter. The transmitter does NOT use or understand the *.otx format. Yes you can put it on the SD , but you can store most anything you want on the ...

The receiver would operate fine on a 2s Lipo, 4, 5, 6 cell Nicad or Nimh or AA....but your servos may not operate or last long. Servos generally expect about 6v.
Yes, you can plug the battery source into any channel or the SBUS port.

Since that shows sbus input, you will have 16 channels available. How many are used by that stack depends on what firmware it runs and what options you put on your drone. As tonnie says, your question is too general to give a definitive answer. But channels available via your X9D and an SBUS capable...

If your flight controller in the drone accepts SBus, There are several small FrSky receivers that will work. RX4R, XSR, and XM+(no telemetry). If SBus is not an option RX4R, RX6R or RX8R depending on how many channels you need. If by radio, you mean the transmitter, the internal RF module can transm...

After you check the box you need to download that firmware and flash it to the transmitter.
Did you do that?

It is still there.
Look under Special Functions.
There is Background Music and Background Music Pause.

It is way down the list, so scroll down to see it.

I don't believe you can save one from within the simulator, I could be wrong. However,If you logged a flight you can load and replay it. From the LOGS, or anywhere else. Since Log files are easy to read, edit and save in OpenOffice, or Microsoft Office or similar spreadsheet programs, you could make...

Two viable candidates are
Bad calibration of throttle channel
and
Maybe you gave a throttle cut set on a new model.

The easiest way to get help is probably to post your .otx so someone can see if there is a setup error.

I did try it. There has to be a buffer or stack to queue up the sounds to be played. If you overflow it you will lose some of the queued files. But the buffer/stack will still be played for whatever is in the queue. Since it takes much longer the 30+- MILLISECONDS to play the sound file, the sounds ...

I think you are dropping in a new playFile every approximately 30 milliseconds. Much faster than the .wav can play. Change the 900 playFile to a print statement and watch the debug output in the simulator full up with printed output. I'm sure you know that the elev goes from -1024 to +1024. I would ...

In the past FrSky has taken a copy of the source for OpenTx and made a version that the OpenTx developers did not consider ready for release made some changes and shipped it with new transmitters. They did not provide any release notes or even the exact date that they took the source. This made it s...

Failure to save is not a message I've seen. Are you sure that is the exact wording? Click on the File tab then Save As in the drop down menu. then get pointed to a Folder and add a name to save it with. But doing it on the Tx makes sure you could modify it at the flying field.... most likely change ...

Thanks, Joao, I was beginning to think it was personal...wrong deodorant?

In Companion right click on the line in the Mix for Elv Just 'Add' a second Mix to the Elv Mix. AilCor is the Name (not required) Source is Ail (Ix:Ail if you are using Inputs for multiple rates) Weights 15 (adjust to your needs) The tricky one is Curve has a drop down box to select Func(tion) Inclu...

Just go to Settings then in its drop down menu there is another Settings click on that and fill in the menu. Be sure to look at all 3 tabs for something you want or don not want. then click on OK. In my case I have to close Companion and restart it to see the new profile. I'm using Companion 2.2.3 o...

(I assume by barndoor you mean flaps at essentially 90 degrees down to the wing chord.) But if you already getting 100 on your channel monitor for 'normal' down flaps, you can't get more unless change the OUTPUTS line for that mix. This may stress your servo...even to the point of stripping gears. I...

|x|is the absolute value of the source, Ail.
So basically no matter which way you move ail, you get a positive value.
It acts likes a 'curve' of 3 values, y = +100, 0, +100.

Even if you want to do all programming on your Tx, using Companion with its simulator to see if what you think needs to be done has the correct effect is easier for many. Since it only costs a little time to download and install, I suggest trying it. And what Jaao said is one way of doing it. Anothe...

The replace Mix line takes 100% of the channel that is controlled by the throttle stick at the TIME you put SWy up.
So that channel is held at the value until you put the switch down.
Then the channel will jump to where the stick is presently positioned.

In the mixer add a line after the Thr(gas) line
Chx Thr weight (+100%)
:= Chx Weight (100%) Switch Sy(up)

Note := is Replace in Companion

Use a Telemetry script. As I'm flyer, I use voice for in critical flight information so I do not have to look at the lcd. Since I don't necessarily have the telemetry screen showing, I often put critical announcements in background(), but if there is nothing you want to setup initially or run even w...

If that is the complete program, you need to put a wrapper on it. local function run() lcd.clear() lcd.drawText(1, 1,"drawText() example", 0) lcd.drawText(1, 11,"0 - default", 0) lcd.drawText(1, 21,"BLINK", BLINK) lcd.drawText(1, 31,"INVERS + BLINK", INVERS + BLINK) lcd.drawText(120, 1,"XXLSIZE", DB...

In Companion there is a tab called "File", click on it and the next to the bottom item on the list is "Synchronize SD."

OK by standalone I assume you mean on the transmitter. I do not know what FlightDeck is, have you got a link? just curious. I would start here http://open-txu.org/home/undergraduate-courses/fund-of-opentx/part-3-understanding-boot-loaders/ then go on to A brief look, I did find a tutorial for updati...

First you do not have to upgrade if both transmitters are on the same firmware. Companion for 2.1.x is available at https://www.open-tx.org/2016/09/15/opentx-2.1.9 But if one tx is old and one is new, they may not be on the same firmware. You must confirm that they are both at the same level of firm...

Oh, and of course your SD cards have to be duplicates of each other, of course. (Contents wise, not size wise.)

Good luck!

The first thing to get in your mind is that the transmitters calibration data is stored in the .otx file that contains all the models on each transmitter. So you cannot just read the models form one tx into Companion and write it out to a second transmitter and have a working second tx. I'll assume ...

1, 2, and 3 are correct, if you imagine when you connect your tx pops a menu and asks you to select Joystick or Mass Storage. I think 3 only allows you to see SD, but you can write firmware with the correct USB driver...?? I've only used it to manipulate the SD card contents 4. I also have no idea, ...

Does this clarify it?

Too late.
