Put the transmitter in bind mode first. Then power to the reciever.

Found the problem. I was using a power supply at 5.56VDC. For some reason it was fine for binding, but not for flight mode. Was thinking what was in common to this new "matched radio and receiver" and the 1-yr old Tx and Rxs. The power supply to the Rx was the only thing in common. So found an old ESC that wasn't an Opto and used it's power supply. GREEN Light!.

Taranis and Tanks?
 

Taranis veterans, I just ordered the X9D Plus Special Edition and would like to use it with a Heng Leng Abrams tank that will be running an IBU3 motherboard. That motherboard accepts PWM (pulse width modulation) inputs but not SBUS or IBUS. I purchased the FrSky X8R receiver to use with the X9D Plus because it supports PWM input (although, if another receiver is better for lowly ground vehicles, maybe someone can point out which receiver would be better). Since this is obviously not for an aircraft, can anyone walk me through the steps I need to follow to get the X8R bound to the Taranis TX and so that they both communicate with the tank. I do not think it will be that hard but this is my first RC vehicle ever

Also, I would like for the left stick to be self centering in both the X and Y axes. In order to do that, do I remove the holding screw from the metal arm inside the gimbal? (this model has the Hall Effect gimbals, so perhaps I need to do something different?)

Thanks for any help that you guys can provide!

How can I set up a QX7 I am trying to figure out.

a. both sticks self centering
b. ability to use Clark board, IBU or Tamiya tanks
d. ability to assign driving to one control stick
e. turret rotation and elevation of gun to other stick
f. This is a biggie. ability to assign a switch on radio to fire fire main gun on tank
switch to fire machine gun
switch for engine sounds
switch for headlight

Taranis QX7 Problem
 

Hello, I am new to the forum. I fly multi-rotor quadcopters and I am having problems with my radio programming. When I try to assign switches on the radio they don't automatically set and I am unable to manually find the switch. I don't know how to fix this. If anyone could help I would appreciate it. Thanks Doug

Big project for Horus X10S and therefor questions ;-) ?
 

Hello, I need a special setup for a special (airplane) project and I think the Horus X10S mixed with other technologies will the perfect match, but I have a few questions for you frSky specialists:

1- I need to program a sequence of event pretty complex,
like a door sequence, the sequence is going like this:
a. For open:
i. Open the outer door (5 doors with 9 servos, all must
be adjustable individually)
ii. Open the inner door (1 doors with 2 servos, all must ‘’ ‘’ ‘’ ‘’)
iii. Lower the wheels
iv. Close the inner door
b. For close:
i. Open the inner door
ii. Raise the wheels
iii. Close the inner door
iv. Close the outer door
2- I need 9 channels to be s-bus compatible (ideally
Futaba) to go through a Deamon Cortex Pro gyro
3- I need to be able to do 14 mixes (in addition to the
doors/wheels sequence), mainly aileron 1 to
aileron2 (with reverse and endpoint adjustment) type.
4- I need in total 27 channels, so it will be 2 receivers, one
normal (Rx8R) and a s-bus compatible (R??).

Can you tell me if it’s feasible and with which component I should go? (Receiver model ?) Please provide as much detail as possible as I came from a Futaba world and did use only this brand since always !

Thanks a lot!

I got the same problem, thanks to this thread and got my issue fixed already.

Can Horus call out the sequence of an F3A Scehdule via the press/toggle of a single switch?
Example:
First toggle/press of the switch horus says - " Double Immelman with Knife Edge flight "
Second toggle/press of the switch horus says - "Trombone with roll"
Third toggle/press of the switch horus says - "Golf Ball with ½ rolls"
Fourth toggle/press of the switch horus says - "Inverted 2 turn spin"
Fifth toggle/press of the switch horus says - "Two slow rolls opposite"
And so on for maybe 15 switch presses

How generally speaking can Horus programmatically do such a thing? Please give me a rough idea.
Thanks for any reply.

taranis 9d
 

I just bought a taranis 9d plus my computers will not see it's sd drive I have try everything any suggestion

Hi, can someone please explain to me how can I get a second throttle set on a switch (a few rpm higher for exemple, for gas planes). There are videos but it's made through the PC, I want to make it from the radio. I've managed to make flaps to elevator mix, timer on a switch, but not a second throttle set. I have the Taranis X9D Plus EU version.

Hi, how about in the mixer page, add a second mix to the throttle channel. set the weight, and set to replace then assign a switch to it.

Yes, thank you! I've managed to do just that. It works great.

Hi all-

I have searched high and low and emailed vendors all over the place to find out if:

Is there a module that can be added to a Taranis X9D Plus that supports JR XMSS technology? In other words can I get an equivalent signal from this transmitter that I get from my JR XG 11?

I've read and seen and have had recommended to me various JR modules all of which ultimatel cannot support the XG 11 equivalent.

I am coming to the conclusion that such a module does not exist.

Let me know what you think.

Dual and triple rates with two aileron channels. Open TX2.2.2
 

I have set up a program for my tug plane (ailerons and flaps - 4 servo wings), in my new Taranis X9D Plus flashed with OpenTx 2.2.2.
I have both servos operating ok.
I entered two lower rates in the aileron channel #1 in the mixer and the result is as it should be: the ailerons function accordingly. (resulting in triple rates).https://cimg1.ibsrv.net/gimg/www.rcu...9258fea653.png

However, I did not enter the same two lower rates lines into Channel #7 which is my left aileron.

The output of channel #7 (left aileron) is the same as that of channel #1 (right aileron). (Corrected below).

How does this occur when I have yet to enter the second and third lower rates lines into channel #7?
Is this an automatic function as a result of choosing it in the set up wizard?

Jim.

Edit:

What I have posted above is wrong. The two ailerons do not move the same deflection on the lower rates, as I have programmed above.
It appears that it would be best practice to put the two lower rate lines in the aileron inputs and not the mixer.
Correct?

Correct!
All things that effect the overall control authority of a stick/slider/pot/switch (like rates or expo) should be usually done on the Inputs page. Use the Mixer to link an Input item to one or more Channels (and further modify the amounts, if needed). So normally put all your rates/expos on the Inputs section for that control. This has the advantage that if you need to change the amount of a rate (or expo), you only have to do it once in one spot, rather than doing it on multiple channel lines in the Mixer. And it keeps things separated and therefore less possibility for confusion.

Note that the Inputs page is just a list - things do not have to be listed in channel order there, so your aileron stick could be #6 on the list, and as long as you link to that Ail on the mixer page for Channel 1, all will still work just fine.

On the mixing page when selecting a source, there can be two choices: "I1:Ail" (for example - which is short for "Input list item #1, named "Ail") which is the result of the Aileron stick AFTER any rates/expo/etc. have been applied from the Inputs tab. There is also a plain "Ail" selection, which is the raw 100% value coming from the Ail stick without any adjustments. It's easy to pick the wrong one, and then things don't seem to work correctly. To help keep things clear, I usually rename the Input to include the letter I. So "Ail" becomes "AI". That helps me make sure I am using the result rather than the unmodified stick amount in the mixer, unless, of course, I really want to do that.

An exception to the above is if you are only doing very simple modification to the authority for a control, then it doesn't even have to be listed on the Inputs page at all. Just use the raw value version as a source on the Mixer. This is most commonly done for switches, where all you usually want is the native +100,0,-100 values coming in to the mixer, and then modifying it there to send the actual amount of motion desired out to the servo.

There is potential for error here for the beginner! I will have to read this several time to remember it.

I am correct in translating that to mean that MAX can be used as in input to the mixer?

Thanks for the reply.

Jim.

You can - you can use MAX directly as a source in the Mixer. Or you can use it in Inputs first, where it gets modified with different rates, before being passed on to the Mixer. I do that with flaps generally - use MAX with rates controlled by a switch, rather than use the switch itself as an Input source. Less confusing to my weak mind when I try to keep track of what values are being passed along.

Thanks for that explanation Ted.
I have yet to understand how a "switch" can function as an input source.
Can you explain for me please?

Jim.

Using the elevator stick as an example, you know that it has a range of values from -100% at full up, to +100% at full down, with zero in the middle.
A switch acts in the same way. For a three position, it can send +100%, 0, or -100%. Of course, nothing in between those numbers. For a two position, it either sends +100 or -100.

So for flaps, one could setup the linkage in the plane so that with a switch up, the servo moves to full flaps up. With it in the middle, they drop halfway. And with the switch down, they drop all the way.
On the inputs page, you would just list the switch as the source, and then link it to the flap channel(s) on the mixer page.

Here's an image using SA as a source, as compared to using MAX controlled by SB. For this example, I just linked source #5 to channel number 5, and source 6 to channel 6 on the mixers. Note they both move the output from full down, to middle, to full up.

In this, using the switch seems simpler - it's only one line, instead of 3. Reality is that you would still need 3 lines for SA (to avoid building linkage on the flaps that matches perfectly), each with its own weight and center. So SA would be both the source AND the switch used to select whichever input line should be active. Which is shown in the second clip.

I still stumble over the weights - SAdwn means send all of the switch authority (which is -100% in that position) to the mixer.
SBdwn, because what is shown as the weight is also what goes to the mixer, seems more explicit to me.

This is the advantage and disadvantage of the OpenTX system. There are always multiple ways to arrive at the same destination!

So far, I understand.

Still with you here.............but..........

All the remainder of your post, has me totally puzzled, especially the screenshots.
I am assuming you have two flap servos. Right flap is designated "flap", while the left is designated "flap2". Correct?
And it looks to me like two switches have to be operated simultaneously in order to deploy both flaps together.
In the first example in the first screenshot, it appears as though only the left flap would deploy upon operation of switch SB.

But this must be wrong! My interpretation, I mean must be wrong.........surely?

Sorry to have to ask again, but I need more assistance with this............otherwise, I will remain more confused than ever.

Thanks,

Jim.

Sorry - I was just focusing on two different ways to define an input to drive a single servo. Combining the two different ways to show on one screen could be confusing.

If you wanted to use a switch directly as a source, use the line shown in the first shot for I5. Do not enter the lines for I6 that use MAX. Over on the mixers, link it to the servo channel(s) - channel 5 if you have just one flap servo, channels 5 and 6 if you are driving two servos. One input, driving one or two servo channels.
The second shot, for I5, shows using the same method, but allows you to play with weight and offset to fine tune where the servo arm is for each of the three positions. (there is another way, that is arguably much better, but that leads us down another path that I will avoid for now....)

To try out the second version, start over, but instead use the lines I put on I6, and skip the lines for I5. Link I6 to either ch 5 for one servo, or ch 5 & 6 for two servos.

They both end up doing the same thing, except that I5 moves flaps by using switch SA, while I6 moves flaps using switch SB.

"Could be confusing"?
If I have read the title of forum, it is a beginners support forum.
This is a common problem I encounter on other, less beginner friendly threads. The experts offering advice know what they mean! (which is a good start). But communicating that to the beginner is not a common skill.
At least you have responded with an explanation, thanks for that.
I will now go back over your posts and try to understand with the above "code breaker" in mind.
Thanks again,
Jim.

Edit: Can you tell me the correct way to post my set up in Companion as you have done in examples above?
Other than taking a screenshot I mean.

Jim - I didn't take you for a raw beginner, given your shown ability to use Companion, and the level of what you have already done. Hence "compressing" the explanation on my part. I also incorrectly assumed that you might experiment by duplicating the examples given in Companion (and that you were advanced enough to not need shots of the mixing tab to get it all to work), and seeing how each variation works in the simulator.
My post above were also just screenshots of one part of a setup to illustrate what was applicable to the question about inputs. In my case, I used the "Windows Snipping Tool" to make the screen shot. But however you did it is just fine, also.
You can also save the model file from Companion, and then attach it to a post. That will allow others to download and look at in Companion. The downside is that others may not bother to do so, and then would skip over offering help. And there can sometimes be mismatches depending on which version of OpenTX you have, and what they have.

Note that this forum does not like some file types, so I had to rename the attached file to end in ".txt". After you download it, change the name to "example.otx" so that Companion can read it.

Attached is a simple example. Model 1 uses switch SA directly as an input source, to control two channels (servos) for flaps in the mixer. Model 2 uses MAX, (and switch SA to change the MAX values), to control the two servos.
I'm running version 2.2.3. It will be an interesting test to see if your version will read it. Just save the attachment to your computer, rename, then use "File", "Open" in Companion to see it (if it works).

If this works, save your file, rename it, and attach it in a response. I'd be glad to edit it, and then discuss what changes I made, and why.

Ok, my screenshots were done with the Linux Mint screenshot tool.

Ok. I have done that. Thanks. Lets see if my post with the attached file works.

Jim.
