How Channels in OpenTX work: mapping and changing the order (Taranis, Qx7 and T16)

[@leslieshapiro2225]

Lee You helped me out when I brought a bix 3 and Installed a Eagle Tree Vector with a 3 - Pos switch ❤️ Plus’s things like throttle timers/rates/ special functions/ sounds.....etc with out YOU and your easy to follow step by step instructions helping people “new and old” to this hobby actually understand how to set up their new Model/ radio / receiver. I purchased a Taranis plus’s radio after watching your video (which I still use today) I just want to say a big THANK YOU. pS I’m sticking with Taranis 👍

[@fcass]

I didn't need this one, but I just wanted to point out that you are an excellent teacher my friend. The hobby is blessed to have you explaining these sort of things for everyone. Well done. Brilliant. Cheers. -(VRMan)Fred C.

[@ChrisBalmforth]

Well explained as usual, especially changing the channel order. When I'm setting up a new model with OpenTX I start with the Input page as you advise, then I jump to the Output page and label the channel outputs eg, AIL, ELE, THR, RUD etc. That makes it a bit easier when I then move to the Mixer page because all the channels are now labelled. A tiny thing, but it helps me!

[@Painless360]

I agree. I do think that OpenTX should copy the mixer names into the output tab. Would make it easier... happy flying!

[@eladdov8601]

Thank you for this video, I have been a lifelong JR/spektrum user and just switched to the jumper t16 after my trusty old jr9303 gave up. this video really helped me understand the input and output pages on opentx. The presentation is exceptional, short and to the point!

[@Painless360]

Glad it helped. The start of the OpenTX series works from the basics for those coming from Spektrum/Futaba or other radios and covered what you need to know in the first few videos.. Best of luck!

[@ajosepi1976]

You can also edit each channel and go into the expo screen and change it there. Make sure you are on the right channel number and in the expo screen go to source and move the stick that you want it to be on. For some this is easier because they can't keep Ele, Ail, Thr, and Rud straight in their head, but they know "I want this stick to make it go right." Great video.

[@leeseaman4193]

Many thanks Lee for yet another super post, for us newbies with Jumpers,Q's or plunging first time into Open TX there are dozens of really handy tips and processes here for sure. Having just changed to a Jumper and and added at your reccomendation the very compact Kopilot all I've to do now is decide for the three way Channel 5 whether to set it up the order on inputs or the mixer.

30 years ago the multiplex europa sprint already supported "channel mapping" the same way it does servo reverse ; you just plugged the wire from the stick pot into another port on the pcb inside (or turn it round for reverse) Still have mine in use :)

Hi everybody. I've just bought a Jumper T16 and when i've updated T16's multiprotocol module firmware, i had to choose a specific channel order for the firmware file. It's a must to use that channel order when using infernal multiprotocol module or can i change order in mixers page and keeps all working ? Thanks.

[@MCsCreations]

Awesome tips, Lee! Thanks a lot! 😊

[@HanZie82]

[@438fpv]

Perfectly explained. I've got a random question, currently building a little rover to play about with over the winter, I'm wanting the throttle to have full stick throw but only have fowerd, then flick a switch to go reverse. Also is there a way of making the sticks control 1 servo, then flick another switch to control a completely differant servo?

[@Painless360]

Yep, check out my RC car playlist:)

[@fonwoolridge]

Thanks! Demystified a little more of the Taranis for me LOL!

[@funKdatFPV]

I am not able to see the sticks move in the channel monitor on the models main page. What could be the issue?

[@Painless360]

Could be a few things. If you've not added the inputs to any of the channels in the mixer screen would be the first thing I'd check.. Use the model wizards to setup a model first time to avoid the majority of pitfalls.. best of luck!

Took a break from RC since 2021 back now and of course forget everything. I needed to map certain controls differently because I'm using a stabilizer receiver. I changed the order to match the receiver on the input page. Was I supposed to do that on the mixer page instead? It works I was able to edit each one change it.

Use the mixer to change the order. Best of luck

HI Painless360-- thank you for your videos! When using the X9d 2019 taranis, channels 1-4 work in the output channel monitor. I set up a 3 switch toggle for channel 10 for the s6r receiver, but when I flip the 3 toggle switch, it doesnt show in the output channel monitor on the taranis so i cant control the flight modes. Same thing with the gain knob on channel 9. What am I doing wrong?

[@FPV420.]

Dear Lee, Thank you for your video. After a few days of trying to solve my new delta plane setup with Arduplane (not my first delta) and FRSky R9 Mini (sbus) I really need your help. In Arduplane, radio calibration, no matter which channel I assign to THR, the slider (in mission planner) for THR will always be the roll one. If I change RCMAP mapping it still will be this channel (roll) that will control the throttle so the motor moves. I am lost. In Taranis QX7 INPUT I have TAER. In MIX I have AETR, but the issue is no matter how I rearrange the channel Arduplane will always take the roll as Throttle. This is causing issues since as soon as I start the plane the ESC will go into programming mode. Any idea how to fix this? Thank you.

[@Painless360]

I don't use the R9M here. Can you not just move the channels in the mixer on the radio?

[@FPV420.]

Im using an FR Sky Taranis X9D + and currently have the SD switch programmed to enable / disable the gimbal and I also have pitch so it is going up and down using the RS (Right Slider) on the radio but I cant figure out for the life of me how to get Roll and Pan working as well as getting the MODE working or switches to turn the camera on and off from the radio or switch between photo and video mode etc.. Would really appreciate your help if possible please. Im using the FR Sky X48 reciever. Cheers

[@rubenvaneupen7327]

I want to output the throttle of a buddy/slave radio to the channel11/aux11 on my (crossfire/ghost) receiver. This cannot be done by the easy TAER mapping method in open tx. How can I set up the input and mixer pages so that this is possible? I guess the buddy radio for example can already copy/map the throttle to his channel 11. And then I can input it just like that? Not sure if that is necessary and maybe I can directly select the throttle from the buddy radio as source for my input/mixer channel 11?

[@Painless360]

Easily. See my videos on setting up the trainer function... best of luck

[@ronchampagne8484]

It appears that channel numbers also appear on the input page . So why then do you need BOTH a input page AND a mixer page ? Other than mixing a channel from multiple inputs I don't see the reason to have both . If you have a straight forward setup with no mixing of multiple inputs for one channel could you simply leave the mixer page blank if all the channels are allocated in the input page ?

[@Painless360]

In simple models it does appear like duplication but Che k out the videos in the Opentx mix school to see how much power they add to complex setups.. Happy flying

[@gaidkey1128]

how do you reverse a channel.say pitch forward is pushing you in pitch reverse.how do you reverse that?

[@Painless360]

There are three ways in OpenTX. You can change it using the polarity of the control amount in INPUTS, MIXER or by reversing the channel in the OUTPUTS screen. Check out the OpenTX Mix School playlist for more detail.

[@justforkicks6755]

Great video, love your channel. In your opinion, if you were getting your first radio, and planned on mostly flying fixed wings, which would be the easiest to use and the most cost effective, if you were doing bind n fly, with safe, and lemon TX receivers for plug and play? I have the Jumpertx 8, and I just cant get it to work properly with gyros etc.

Thanks for this, very useful. I've been flying quads for approx 18 months and this stuff is still a little opaque. Question for you though: I only have AETR set up in inputs, but the rest of the switches straight into the mixer tab without them also being added to inputs. It works fine. Is there any downside to this approach? Or should I also set up all the other channels (buzzer for example) in the inputs page as well as the mixer?

[@Painless360]

That is fine. See my Betaflight BNF setup video. If you are doing all of the 'smart' stuff in the flight controller then you don't need the input pieces for switches..

With your videos, I have learned a lot about open tx, and how to do almost everything. But really what I am missing is to find a video that explains to me which are the most usual mixtures that are used, that is, a configuration of an airplane model such as a high wing trainer, or a low wing, or a warbird. Learn to configure a model completely, not loose parts that you do not know if it is what to apply or are just examples. Could you make a video of this style? Thanks for your dedication.

You watched my OpenTX Simpler plane setup videos? Or its companion - OpenTX Complex Plane setup? They are both on the channel...

[@ec-cts6602]

@@Painless360 Sorry. I have explained very badly. I did not want to say how to configure the servos. I was referring to the most common mixtures, for example: Correct the adverse yaw effect, rudder-elevator, etc. Many of your videos explain how to do it, but for those like me who are starting again, an explanation of which are the most normal mixtures used is missing. Your video of: OpenTX Complex 'Plane Setup Tips is a great advance and it is magnificent, in fact I have followed how to configure a model based on this video, but (in my point of view) it lacks to explain the mixes that would complete the programming . Those of us who don't really know what mixes to put on have learned how to make them, but we don't know what mixes need to be made (the most normal mixtures that should be put on any plane -on the whole-). I hope I have explained better. If in some of your videos you explain the mixes that must be made to a model, excuse me, but I have been unable to see it. Greetings and again thank you very much. You are serving as a guide, as you can not imagine.

[@Painless360]

Ah I see! Nice idea. What mixes would you like included in a video?

[@ec-cts6602]

@@Painless360 I thought like a beginner pilot. The basic mixes of an airplane to start; then some for advanced pilot; and any others you may think appropriate, for example setting up a warbird plane, or an aerobatic plane. This can really lead to several videos, because I think that in one video you could not include so much pretense together. But always thinking of a set of mixes that cover all aspects of configuring an airplane to put it in flight. For example, think that you have an airplane that has ailerons (2 servos), that has flaps (1 or 2 servos), with a normal tail, that you want to have several flight modes, a smooth one, a medium one and a nervous or aggressive one, or modes of take-off, cruise, landing. If I think about it, I think of all the basic possible mixes I would need to get this plane up in the air, with minimal guarantees. This would be a type of basic configuration, which every aircraft has to have. After this type of airplane, variations can be made, such as V-tail, retractable gear, airbrakes, etc., etc. Any other possibility Thanks again.

Just installed opentx from FrSky OS I can't even get the throttle on the correct stick. Out of the box it's setup for throttle on the right stick I want it on the left. Looks to me Opentx targets the quad racing community not so much for fixed wing flying.

[@Mike-01234]

@@Painless360 I got it all working thanks for the video really helped. openTX isn't for the type of person who doesn't like to tinker with radios, but once you get past the initial shock of trying to understand the basics really is powerful radio firmware. I had FRos for long time really hindered the controls like the POTS on the back side of the radio were setup like logical switches with openTX I can actually use those wheels on the back to steer a nose gear. If want to get into scale models this is the radio to have IMO endless configuration. Unfortuntly have to forget about how a traditional radio works start over the openTX instructions are not well written for first time users not surprising typical of engineering types who wrote it. Your video filled in the gaps I use the Companion software to program my radio much easier to do it on the screen instead of using the wheels.

One glaring unnecessary challenge in all this. Is the muddle of terms used. MANY MANY users use both Betaflight and Open TX for multi-rotors. Having to "convert" irrelevant and inapplicable "Airplane terms" like Aileron and Rudder into the relevant quadcopter (Roll, Pitch, Yaw) terms EVERY time we define or redefine something, is a waste of time and effort. It feels cluttered and inefficient. Maybe there are enough quadcopter pilots now. Where both Betaflight (et al) and Open TX could branch into "Multi-Rotor versions" of the software/firmware. Where no irrelevant terminology has to be translated nor dealt with. Could even be just one version. Except with the added option to turn off terminology that doesn't at-all, apply. Imagine being a brand-spankin'-new quad pilot: "Roll Pitch and Yaw are the copter directions/headings." "Then WTF is AETR1234?!? At least "R" means "Roll". Right?" "Actually no. "R" means Rudder. Which is really Yaw. AETR is Roll Pitch Throttle Yaw. In that order." "Why didn't they just CALL it RPTY1234 instead? Do I have to memorize that translation to configure this stuff efficiently?" "Actually yeah... Ya do... And just wait til we start on the radio."
