I have ENGLISH CAPTIONS turned on and as it's transcribing what you say in real time, TH-cam think that the moments when you're not talking and just revving up the motors in the background, sounds like "applause". That's what I hear too when we're about to fly FPV. bliss.
You are the greatest. Following this video I just got my system set up with redundancy of 2 receivers and telemetry to play value and play track for low RxBt and RSSI after being overwhelmed for almost a year. It works great!!!!!!!!!!!!!!!
I have accidentally soldered off a capacitor or something off of my flight computer which for better or for worse, made it so that the OSD doesn't work anymore on my kwad. I'm so happy that I found this video.
I hate to admit how much I concentrate on JB's video. Like he is the Talmud and I am a devout. The word collapses as I focus on his tips, tricks, commentary. Thank you so very much.
I guess im asking the wrong place but does anyone know of a trick to log back into an instagram account?? I was dumb forgot my password. I appreciate any tricks you can offer me.
@Holden Wilder i really appreciate your reply. I found the site on google and I'm waiting for the hacking stuff now. Takes a while so I will get back to you later when my account password hopefully is recovered.
Boy I'm glad yer here Catching up with my new T16,,, I never cared about voltage cause I could see it in osd,, but now with dji,,, I have no battery voltage osd, unless I'm missing something, anyway now back to learning to make the radio talk
I just wanted to know how to set it up, you know copy,and paste,but every time I watch your vids I actually learn something!! Thanks Alot!!LOL! Truthfully thanks alot the Logical switch explanation pretty much simplified my thought process!!
In times of digital FPV and slowly developing OSD functionality, as is the case with SharkByte + Kiss/Fettec, this video takes on an unimagined importance if you don't want to fry your batteries. Joshua, YOU ARE MY HERO !!AGAIN!!
Hi Joshua, great video but a slight problem with seeing you Taranis screen clearly in this and previous video------ is there any way you can make it more clear----maybe slight focus or angle of your screen ,,Thanks again!
THANK YOU! I've tried setting up my telemetry/alerts, but every video I've seen they just go through the motions with zero explanation as to how they work. Knowing how they work -> being able to do more!
Hopefully this will save someone some time. JB calls it Vfas in the video I didn’t see that option. So I selected RxBt except it has a regular , + , and - . The + was the highest and the - was the lowest voltage it hit in the flight. So the regular one is the one you want. Everything else was the same, Great video JB!
I've sampled that YO! part, definitely will make it as my low battery warning :D If everyone wants to do it, you need to save the sound file as WAV with these parameters: bit depth - 16bit, sampling rate - 16khz Taranis can read this format WAV's.
Josh you did the 0 volt thing the hard way. There is no need to add L07, all you had to do was on your L06 was add your AND condition ARM SW. Then it only gives volt info when armed. Silent otherwise.
When he chained it with the logical switch tied to RSSI, I think it could be: L07 = RSSI > 0 for 5 secs AND L04 (his logical arm switch), and then L06 = VFAS < 14.0 for 0.2 sec + 10 sec repeat delay AND L07. Would that work? If so, still does it with one less logical switch. I guess if we wanted to use RSSI > 0 for something else, it might make sense to give it its own logical switch. OpenTX is very cool!
Hey Joshua, thanks for the video. I do not have VFAS or RSSI but do have RxBt and 1RSS/2RSS ... are these the same? Since I'll be flying 6S but may occasionally run 4S, I modified your logical switches to work for both, but have to reboot the Tx if I change packs since it uses highest voltage ... not sure if there's a way to get around this but FWIW here's what I did... L04 a>x RxBt+ 22.8V --- --- --- L05 a>x 1RSS 0dB L04 --- 0.2 L06 ax RxBt+ 15.2V --- --- --- L08 a>x 1RSS 0dB L07 --- 0.2 L09 a
Hi , thank you very much. But the camera angle is not correct and I can not see the transmitter screen what you are doing. Can you please kindly guide me simple step to step to set low battery warning on my FRSKY qx7. Thank you
You're quite suitable on time with this Taranis series, Josh! I am right now sitting in front of my new cl_racing f4 with the x4rsb and my Taranis and going to push the magic buttons xD
You have a great channel. I always watch your videos. Never know what I'm going to learn next. One thing i would like to learn about, and i can't seem to find much information out there about it is. Running all the motors on the quad in reverse rotation.
Link to OpenTX University: open-txu.org/ Thanks for another useful video tutorial! I've been a hardcore logical switch creator/user on my Taranis since the first week of owning mine - going on 3+ years now and I've always required telemetry on my rigs for that reason. Many of my flying buddies choose not to mess with it because they feel it's too complex to learn - but now I can source this video to such folks so they'll no longer have an excuse IMO... ;-) not that there hasn't been other videos on the subject, but this one done the JB way, makes it soooo much simpler to understand for those that easily get overwhelmed by such. Thanks again! - videos like this will be forever useful to our ever-growing community of Taranis newbs.
Thanks for this great video, I've set this up on my TX16S. Would you perhaps know how to disable the default RX battery warnings, as I now have both running?
I know this video is old, but this is solves my exact problem. I am a LOS drone pilot and I need a way to monitor 6s to 8s voltage. I just need to know what transmitter are you using with this controller?
Josh, Yet another great video from you! I just wanted to thank you for all of the great information that you share in your videos. I, for one, have found them to be extremely useful and and very appreciative for all you do!
Is it possible to check which quad i am using if i use a 4s one and a 2s one for example? So i could make different logic swithes with AND logics to check for 14v on a 4s quad and for 7v on a 2s quad.
Thanks for this Mr B, can I just punt in that in crossfire the telemetry value is called RxBt (according to Mr Liang) might save another noob a spot of head scratching.
Hey Joshua, we need a video on how to put together the little circuit to put smart audio AND audio on the same input for the Unify Pro. I know there are diagrams out there on how to do it, but at least I can't read them... Good video idea.
I just use delay set to 5s, this means it ignores punch-out voltage drops and it solves the "zero volts" condition without the need the extra RSSI and VFAS logical switches. So when the voltage goes below my threshold for more that 5 seconds then it alarms. In Special Functions I set the sound and haptic warnings to repeat every 3 seconds, so once the logical switch becomes true I get repeat warnings...
agreed, the threshold needs to be adjusted to suit the flying style and lipo capacity etc, I use 14.5v and my lipos generally land at about 15v still in the tank. Cheers, Ray
Great vid ... as ever and a question ... do you need the additional two logical switches (0V & telemetry lost) when using „delay“? ... have to check this out tomorrow
This and some of your other taranis videos got me thinking that it would be nice if there was a library of installable switches, etc. that could easily be added to our tarani. Being new to the hobby, I'm not sure if it is possible to download and install such things. Another thought, being as how I just watched your model match video, it would be nice to have telemetry be normalized to 1S regardless of what size battery being used. That way 4.2 volt is always fully charged, etc. All the alarms and such could be set based on that. Your argument for model match made a lot of sense, and if I spend a bunch of time really dialing in my model it would be nice to use it for as many quads as possible, even the 2" ones using 2S or 3S batteries.
Betaflight reports a "cell voltage" sensor which might could be used to do the 1S thing you're asking for. However it's just an average of all the cells, based on Betaflight's guess as to what voltage battery you're using.
I was trying to set up the audible alarm on my TX12 but could not find the Telemetry option? Do I have to do something to make this available on the menu or just have a better radio?
Excellent instructions I want to ask you, if I have more than a Quad added to my radio control, should I do this procedure to each one or is it a single configuration for all?
I fly VLOS pretty often, and I don't see this changing when I upgrade my quad and have a working VTx and OSD. When you're VLOS, you don't have an OSD, and when you're rippin' while VLOS you can't look down at your screen. Audible alerts are VERY useful for this use case as well! Also, thanks, now I've mapped my switches to announce flight modes. Personally, what I'd probably map is that it announces when you dip below, and if you *stay* below it'll sound a chime/siren/alarm noise for the duration that the switch is active. I haven't poked through my T16's sound library, but probably something that's not TOO obtrusive as to make me want to throw the thing, but gets my attention that something's wrong. Then reads again after, say, ten seconds.
When I started flying I used the same method to warn for high altitude as I live directly under the final of a major airport (further than 5 nautical miles)
I an older first gen Taranus. I was stupid and got a Jumper TX this summer and it has intermitten disconect issues. Anyway my Taranus does not do what yours does what version of open Tx Re you using?
Josh, wouldn't you want to do a logical switch of VFas = Xvoltage (for a duration of Xtime)? During flight vltage spikes and crap can dip the voltage below your example of 14v and read out an audible alert. During the course of a freestyle flight the alarm will be going nuts. I've done this, tried it and it does go nuts. Rotorriot did a video on Taranis setup and covered this a while back.
What I want is to have a knob on the qx7 to play music. So you have a volume control. With the 2nd knob it has a half cut so it can play 2 different songs depending on what the knob is set as
I have a question for you. What hapin when we use 20 Meter extention cable on frsky R9 module antina and antina is in air at 20 meter hight. What will hapin , is signal works better or lost? Can you make a video on this with practical thanks
Hello sir, is there a way for the taranis to read out Low throttle warning, for example when m training new flyers, and they reduce the throttle mid flight to let say 20% or 15% the radio should warn either by saying low throttle, or stall, or whatever type of warning it has... thank you for your time...
Yes definitely you can do this. The way I would suggest doing this is as follows. 1. Logical switch for if "armed" or if "throttle cut" is disabled (to prevent false warnings when on the ground). 2. Sticky logical switch that becomes true when "armed" and the 1st time throttle goes above 15%. Sticky switch trips back to false when "disarmed". 3. Logical switch that is AND of the above combined with throttle position < 20%. If you would like more specific help, please email me joshuabardwell@gmail.com
i have kingkong GT 200 and frsky r-xsr receiver . can i get telemetry with this quad? if not what other options do i have to get any alert about its time to land and avoid ruining my battery ? and thank for your videos. like how you explain things.
thanks for the quick answer, im still learning how to control it so im not using the OSD and the goggles to see my current voltage. i bought the r-xsr especially becasue it can do telemetry but i connected the receiver without the s.port becasue i didn't know if the GT 200 FC have s.port connection or something like that. am i missing something here, can i connect the osd data to the r-xsr somehow. im new to this hobby...
Joshua , can you tell pls , how to transfer LOGICAL SWITCHES from one model to another one ? ( models already created long time ago). Is there any way to create GLOBAL LOGICAL switches ? or Sync Model's Properties using TX Companion ?
Hey have you guys heard of the Taranis discharging the battery substantially while it’s turned off? I think my Taranis is discharging the battery while it is off. That explains my completely DEAD pack the other day after it was fine the morning before. I tested externally yest. and it was 4.13v a cell. This morning it’s 4.0v a cell... been off on the bench all night. Replaced the murdered NiMh with a Lipo already.
Hey Joshua, could you please make a video how to set up a taranis warning that works with the mah reading of the current sensor? It seems more complicated than voltage setup, but should be more reliable is the current sensor is set right, right?
I have tried more than once, I wouldn't ask if I did not try it. I use voltage warning since day one, I am not an opentx noob, but there is more in detail about the fuel sensor which I was not able to solve so far
Joshua Bardwell your going to learn something today. You made this simple thing very complicated with all the extra logical switches for o.o volts warning issue… just add a “AND” value to the original logical volt read out line (L06) by only checking when armed by adding the value of your arm switch as the “AND” switch ie, SA-. Boom no zero read outs unless you have your drone armed with no battery!
I love and appreciate all ur videos without ur help I wouldn’t even been able to get my first drone off the ground and many more I’ve used this method in all my tiny whoops and it worked perfectly but on my 5inch quad the value displayed and read out only says 3.5 volts for my 4s battery and in my goggles it’s over 15.3 any suggestions would he greatly appreciated
I got everything set up and double checked the wiring on my rooster, but it keeps reading 4.9v (so basically 5v) I don’t know where my receiver is getting that number from or how I can fix that. Any help would be great!
It was a little bit hard to read the screen of your radio Joshua but a very good video all along! I prefer using A4 over VFAS for voltage reference, more interesting if you fly with 2S, 3S, 4S, etc on the same build or different builds... Have a great weekend and keep on flying!
ABMNS PRODUCTION I have my brand new qx7s I am new to open TX and taranis, can I use A4 instead of vfas as I will be changing between 3s and 4s batteries
matt neale Hi Matt :) Yes you can, it gives you the average cells voltage of your LIPO which is more convinient than VFAS if you use different voltage ones (4S, 5S, etc...). Use the low voltage and critical values that you think important for you. Or simply translate the voltage use by Joshua in his video by divided the values by 4 since he is using 4S and you will have your values for A4. It will work for any kind of LIPOs since they all have same cell voltages reference :)
Hey Josh....can I ask for your recommendation on how to configure this when flying a mixture of 2s/3s on a mini quad. Got it setup perfectly for 3s but do I just duplicate the logical switches further down for a second battery type or is it better going with voltage per cell when flying different battery types?
I'd go for voltage per cell personally. It sounds simpler to me, and gives you a consistent number that you don't have to convert when flying different packs. You just know that when you hear "Three point four five volts", no matter what you're flying, you need to be on the ground.
just picked up an LR1000 diversity RX, powered it up on the bench to a brand new taranis, bound ok. "discovered" telemetry sensors and only RSSI shows up, i have the telemetry wire on uart1 tx and in configuration i have telemetry set on uart 1 (it's using uart1 for sbus in too), any ideas ?
Hey Joshua my taranis will read put the incorrect voltage sometimes like if the voltage is 15.9 volts it will say 15 volts and sometimes the voltage is off by .3-.5
+David Farris II FrSky runs opentx which can do anything. FrSky is way more cost effective once you add in the cost of receivers especially. FrSky supports advanced features like Lua scripts.
Great video Joshua ! It's working thanks to you. But just a little problem. My taranis only says 3V instead of 3.4V for example. Do you know why it's not reading the values after the dot ?
Ok it's April 2020 and I have the same problem described by geoff here in that when I "play a value" I don't get the decimal place i.e. it says 3v instead of the real value of 3.5v. Has anyone got an answer for this? I've been searching far and wide for an solution which has led me to many dead ends like this 2 year old video. With the passage of time I'm hoping that either geoff or Joshua has the solution. If you do it would be much appreciated if you could post it here. Thanks!!
+Joshua Bardwell Could you do a video on OpenTX to OpenTX trainer & slave setup in the near future please? I wanna teach my sister to fly RC soon but have no idea setting it up.
Well, damn. You're making me want a Taranis. Can you do any of these things with the Turnigy Evolution? Or do I need to wait until it gets hacked with Open TX? (I'm getting my Evo today). Thanks for the video!
The evolution is fairly straight forward compared to opentx. There are some videos out there so just browse around. It will do audible beeps for rssi and vbat, they work pretty well. It can’t interface with your fc for voltages though so no osd support.
How did you get your Taranis to show the full battery voltage on the screen? Mine just shows 4.91volts when my fatshark show a total of 15.0 volts. I have a 4s battery.
what about setting like a 3 second delay so the 0 volt thing doesn't happen or when your doing a pinch voltage sages then comes back up when you let up
Hi -I know this is an old thread but when I go into Logical switches 2nd input to choose telemetry, i have nothing after GVars, telemetry not a choice , can I get some help with this please. Mark
You have to have telemetry working, such as SmartPort for FrSky, or Crossfire, before telemetry will show up there. If you are using a receiver that does not support telemetry, that option won't appear.
Hi Josh Thanks for the quick reply. I'm running the Frsky D8R - 'll plus accst Telemetry. This is on my Align 5ooX. With Beastx When I turn the helli off Tx tells me , Telemetry lost. So must be reading something. Is it possible I've missed something in Tx setup. I'm not really using any other Telemetry features but though this would be of great value to me maintaining power. Hope you can help. Just found some of you tutorials. & subscribed.
and another question ... is there a chance to read out the average cell voltage? ... this would help when switching from 4 to 5 cell aso ... I have seen some discussions about this for cleanflight ... FLVSS ... therefore it may work in BF too
Yes, Betaflight can do this. I can't remember which sensor it is though. I think it might be A4. Check your sensors list and see which one looks like it is average cell voltage.

Yeah. Kinda frustrating you can't even see the screen.
I have the same problem with trying to squint just to see the menu on the radio..!!JB keep this in mind next time plz!
Yeah camera needs to be on a more perpendicular angle

The old vids still useful. thanks
On mine I have also set an AND switch with throttle value below 45 because I don't want battery read out during a punch out.
Throttle Punch that’s a good idea.
Was wondering how to get rid of that!

I learned something new today, so you got a thumbs up! 👍
This explains the a>x rxbt 6 but I'm still not sure, then I use a
almost 4 years later :D can't you just link the function with the ARM switch to prevent the callouts when quad is not armed? aka 0V too?
Excellent video - thank you for making it.
Blinding video very helpful. Cheers Joshua.

As usual, great video.
How would I go about having the OpenTX read out the voltage every 5-10 secs once it is beneath the assigned threshold?
My guess is you should put read it out a big number of time like 30 and 5sec for hold the logical sw.
Is it possible to check which quad i am using if i use a 4s one and a 2s one for example? So i could make different logic swithes with AND logics to check for 14v on a 4s quad and for 7v on a 2s quad.
Thanks for this Mr B, can I just punt in that in crossfire the telemetry value is called RxBt (according to Mr Liang) might save another noob a spot of head scratching.
Thanks for this. I was actually just looking for this exact tutorial, you read my mind ;o)
Love it. Now, how can I get it to tell me when the voltage is < 3.8*#cells ;-)
I am flying 3S and 4S on my Chameleon.
Same here, I just set an alarm to blink in the middle of my OSD..

Another thought, being as how I just watched your model match video, it would be nice to have telemetry be normalized to 1S regardless of what size battery being used. That way 4.2 volt is always fully charged, etc. All the alarms and such could be set based on that. Your argument for model match made a lot of sense, and if I spend a bunch of time really dialing in my model it would be nice to use it for as many quads as possible, even the 2" ones using 2S or 3S batteries.
Betaflight reports a "cell voltage" sensor which might could be used to do the 1S thing you're asking for. However it's just an average of all the cells, based on Betaflight's guess as to what voltage battery you're using.
I was trying to set up the audible alarm on my TX12 but could not find the Telemetry option? Do I have to do something to make this available on the menu or just have a better radio?
Excellent instructions
I want to ask you, if I have more than a Quad added to my radio control, should I do this procedure to each one or is it a single configuration for all?
Hello Joshua... is it possible to get low warning from the internal battery of the Taranis...
I learned somthing from this video today :D
I fly VLOS pretty often, and I don't see this changing when I upgrade my quad and have a working VTx and OSD.
When you're VLOS, you don't have an OSD, and when you're rippin' while VLOS you can't look down at your screen.
Audible alerts are VERY useful for this use case as well!
Also, thanks, now I've mapped my switches to announce flight modes.
Personally, what I'd probably map is that it announces when you dip below, and if you *stay* below it'll sound a chime/siren/alarm noise for the duration that the switch is active.
I haven't poked through my T16's sound library, but probably something that's not TOO obtrusive as to make me want to throw the thing, but gets my attention that something's wrong.
Then reads again after, say, ten seconds.
Bardwell sound pack for Patreon members!!! Make this happen! :-)
When I started flying I used the same method to warn for high altitude as I live directly under the final of a major airport (further than 5 nautical miles)
I an older first gen Taranus. I was stupid and got a Jumper TX this summer and it has intermitten disconect issues.
Anyway my Taranus does not do what yours does what version of open Tx Re you using?
Great info Josh, thanks!
Josh, wouldn't you want to do a logical switch of VFas = Xvoltage (for a duration of Xtime)? During flight vltage spikes and crap can dip the voltage below your example of 14v and read out an audible alert. During the course of a freestyle flight the alarm will be going nuts. I've done this, tried it and it does go nuts. Rotorriot did a video on Taranis setup and covered this a while back.
+Nick I have it set up that way. That's what the 0.2 second Delay is.
ahh ok cool
What I want is to have a knob on the qx7 to play music. So you have a volume control. With the 2nd knob it has a half cut so it can play 2 different songs depending on what the knob is set as
Very nicely done
I have a question for you. What hapin when we use 20 Meter extention cable on frsky R9 module antina and antina is in air at 20 meter hight. What will hapin , is signal works better or lost? Can you make a video on this with practical thanks
Hello sir, is there a way for the taranis to read out Low throttle warning, for example when m training new flyers, and they reduce the throttle mid flight to let say 20% or 15% the radio should warn either by saying low throttle, or stall, or whatever type of warning it has... thank you for your time...
Yes definitely you can do this.
The way I would suggest doing this is as follows.
1. Logical switch for if "armed" or if "throttle cut" is disabled (to prevent false warnings when on the ground).
2. Sticky logical switch that becomes true when "armed" and the 1st time throttle goes above 15%. Sticky switch trips back to false when "disarmed".
3. Logical switch that is AND of the above combined with throttle position < 20%.
If you would like more specific help, please email me joshuabardwell@gmail.com
i have kingkong GT 200 and frsky r-xsr receiver . can i get telemetry with this quad? if not what other options do i have to get any alert about its time to land and avoid ruining my battery ? and thank for your videos. like how you explain things.
You should have an osd on that quad I think, which will let you monitor voltage without using telemetry.
The RXSR can also do telemetry.
thanks for the quick answer, im still learning how to control it so im not using the OSD and the goggles to see my current voltage. i bought the r-xsr especially becasue it can do telemetry but i connected the receiver without the s.port becasue i didn't know if the GT 200 FC have s.port connection or something like that. am i missing something here, can i connect the osd data to the r-xsr somehow. im new to this hobby...
Joshua , can you tell pls , how to transfer LOGICAL SWITCHES from one model to another one ? ( models already created long time ago). Is there any way to create GLOBAL LOGICAL switches ? or Sync Model's Properties using TX Companion ?
You can copy and paste settings inside companion I think.
Will this work for frsky fixed wing receivers or do we have to have telemetry electronics
Hey have you guys heard of the Taranis discharging the battery substantially while it’s turned off? I think my Taranis is discharging the battery while it is off. That explains my completely DEAD pack the other day after it was fine the morning before. I tested externally yest. and it was 4.13v a cell. This morning it’s 4.0v a cell... been off on the bench all night. Replaced the murdered NiMh with a Lipo already.
Hey Joshua, could you please make a video how to set up a taranis warning that works with the mah reading of the current sensor? It seems more complicated than voltage setup, but should be more reliable is the current sensor is set right, right?
+Dennis Riessbeck it's the same method just use Fuel sensor. Also you don't need the delay 0.2 seconds because Fuel only goes up.
I have tried more than once, I wouldn't ask if I did not try it. I use voltage warning since day one, I am not an opentx noob, but there is more in detail about the fuel sensor which I was not able to solve so far
Joshua Bardwell your going to learn something today. You made this simple thing very complicated with all the extra logical switches for o.o volts warning issue… just add a “AND” value to the original logical volt read out line (L06) by only checking when armed by adding the value of your arm switch as the “AND” switch ie, SA-. Boom no zero read outs unless you have your drone armed with no battery!
any idea how to set voltage alarms for my fvlss sensor on the JUMPER TX16.
on my devo, i had alarm for alarm
Brilliant! Just when I need this with a lipo sensot
I love and appreciate all ur videos without ur help I wouldn’t even been able to get my first drone off the ground and many more I’ve used this method in all my tiny whoops and it worked perfectly but on my 5inch quad the value displayed and read out only says 3.5 volts for my 4s battery and in my goggles it’s over 15.3 any suggestions would he greatly appreciated
do u have to make a special Function line for each logical switch ?
I got everything set up and double checked the wiring on my rooster, but it keeps reading 4.9v (so basically 5v) I don’t know where my receiver is getting that number from or how I can fix that. Any help would be great!
You're using the wrong sensor I think. Look for a sensor like vfas that is showing battery voltage.
Very nice😁 thanks for the video😁
Thank you. Works good👍
It was a little bit hard to read the screen of your radio Joshua but a very good video all along!
I prefer using A4 over VFAS for voltage reference, more interesting if you fly with 2S, 3S, 4S, etc on the same build or different builds...
Have a great weekend and keep on flying!
ABMNS PRODUCTION I have my brand new qx7s I am new to open TX and taranis, can I use A4 instead of vfas as I will be changing between 3s and 4s batteries
matt neale Hi Matt :)
Yes you can, it gives you the average cells voltage of your LIPO which is more convinient than VFAS if you use different voltage ones (4S, 5S, etc...).
Use the low voltage and critical values that you think important for you. Or simply translate the voltage use by Joshua in his video by divided the values by 4 since he is using 4S and you will have your values for A4. It will work for any kind of LIPOs since they all have same cell voltages reference :)
Thank you!
Just out of curiosity: what does your L01 do? Could you maybe please make a video about more features of OpenTX? :)
L01-L04 are all used together for the 2 stage Arming switch. There's a video for that somewhere...
Hey Josh....can I ask for your recommendation on how to configure this when flying a mixture of 2s/3s on a mini quad. Got it setup perfectly for 3s but do I just duplicate the logical switches further down for a second battery type or is it better going with voltage per cell when flying different battery types?
I'd go for voltage per cell personally. It sounds simpler to me, and gives you a consistent number that you don't have to convert when flying different packs.
You just know that when you hear "Three point four five volts", no matter what you're flying, you need to be on the ground.
Thank you for this brother your awesome
just picked up an LR1000 diversity RX, powered it up on the bench to a brand new taranis, bound ok. "discovered" telemetry sensors and only RSSI shows up, i have the telemetry wire on uart1 tx and in configuration i have telemetry set on uart 1 (it's using uart1 for sbus in too), any ideas ?
+Daytona FPV you can't use the same UART for SBUS and telemetry.
There was zero documentation for this , that's good to know.. i'll fix that later. new to the dark side :D only got it for crossfire :D
Hey Joshua my taranis will read put the incorrect voltage sometimes like if the voltage is 15.9 volts it will say 15 volts and sometimes the voltage is off by .3-.5
Why frisky and not futaba. New to fpv. Currently running a devo8s Deviation. Any information will be appreciated.
+David Farris II FrSky runs opentx which can do anything. FrSky is way more cost effective once you add in the cost of receivers especially. FrSky supports advanced features like Lua scripts.
Great video Joshua ! It's working thanks to you. But just a little problem. My taranis only says 3V instead of 3.4V for example. Do you know why it's not reading the values after the dot ?
I'm trying to think of what that might be but nothing is coming to me. Do you see the whole decimal point in the display?
Joshua Bardwell yes I see it on the telemetry page and main screen. My taranis is in French but I installed English amber voice pack
Ok it's April 2020 and I have the same problem described by geoff here in that when I "play a value" I don't get the decimal place i.e. it says 3v instead of the real value of 3.5v. Has anyone got an answer for this? I've been searching far and wide for an solution which has led me to many dead ends like this 2 year old video. With the passage of time I'm hoping that either geoff or Joshua has the solution. If you do it would be much appreciated if you could post it here. Thanks!!
@@pbshooter100 Hi buddy. No, I was never able to figure it out. I'm still flying like this nowadays...
@@geogearbex Thanks for the quick reply, I'll keep looking for an answer I guess. If I find one I'll post it back here
+Joshua Bardwell Could you do a video on OpenTX to OpenTX trainer & slave setup in the near future please? I wanna teach my sister to fly RC soon but have no idea setting it up.
My Taraanis -Plus 2.1.6 requires me add a new sensor if I'm to use VFAS. What do I set the Type/Formula/ Cell sensor/Cell index/Logs to?
You really ought to upgrade to 2.2.1. Your firmware version 2.1.6 is pretty dated. I'm not sure how to get it working right.
Joshua, do you know if I can control a WiFi quad such a a Tracker with my Taranis plus?
Hi Joshua!!! What is the battery that you use in your taranis?
I`m downloading this :)
Well, damn. You're making me want a Taranis. Can you do any of these things with the Turnigy Evolution? Or do I need to wait until it gets hacked with Open TX? (I'm getting my Evo today). Thanks for the video!
I would also like to do some of the cool things on an evolution. Like rssi on osd.
The evolution is fairly straight forward compared to opentx. There are some videos out there so just browse around. It will do audible beeps for rssi and vbat, they work pretty well. It can’t interface with your fc for voltages though so no osd support.
How did you get your Taranis to show the full battery voltage on the screen? Mine just shows 4.91volts when my fatshark show a total of 15.0 volts. I have a 4s battery.
You might be looking at the 5V supply to the receiver/flight controller instead of the battery.
what about setting like a 3 second delay so the 0 volt thing doesn't happen or when your doing a pinch voltage sages then comes back up when you let up
Hi -I know this is an old thread but when I go into Logical switches 2nd input to choose telemetry, i have nothing after GVars, telemetry not a choice , can I get some help with this please. Mark
You have to have telemetry working, such as SmartPort for FrSky, or Crossfire, before telemetry will show up there. If you are using a receiver that does not support telemetry, that option won't appear.
Hi Josh
Thanks for the quick reply. I'm running the Frsky D8R - 'll plus accst Telemetry.
This is on my Align 5ooX. With Beastx
When I turn the helli off Tx tells me , Telemetry lost. So must be reading something. Is it possible I've missed something in Tx setup. I'm not really using any other Telemetry features but though this would be of great value to me maintaining power. Hope you can help. Just found some of you tutorials. & subscribed.
and another question ... is there a chance to read out the average cell voltage? ... this would help when switching from 4 to 5 cell aso ... I have seen some discussions about this for cleanflight ... FLVSS ... therefore it may work in BF too
Yes, Betaflight can do this. I can't remember which sensor it is though. I think it might be A4. Check your sensors list and see which one looks like it is average cell voltage.
..exactly the one I needed and working like a charm... next time I check it out by myself first .. as ever ... you are the best
