I have ENGLISH CAPTIONS turned on and as it's transcribing what you say in real time, RU-vid 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.

@mikeoleksa 5 лет назад

These are really cool. I'm glad I found these "audio warning" videos early, while I'm still learning this hobby/sport.VERY USEFUL for a newb, like me.

@BoondockStryker Год назад

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!

@GenCodeFPV 6 лет назад

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.

@JoshuaBardwell 6 лет назад

+GenCode FPV that's not bad. Multiple ways to solve the problem. Ain't OpenTX grand.

@PaulHodgetts 6 лет назад

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!

@gregjohnson5194 3 года назад

Lol I just post the same post with just using the AND arm switch on same L06 line.

@PinchTune 6 лет назад

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.

@LeeLaster 4 года назад

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?

@gcdevicegc6103 Год назад

My guess is you should put read it out a big number of time like 30 and 5sec for hold the logical sw.

@blackmennewstyle 6 лет назад

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!

@M4TTFPV 6 лет назад

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

@blackmennewstyle 6 лет назад

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 :)

@rondefly 6 лет назад

Joshua, do you know if I can control a WiFi quad such a a Tracker with my Taranis plus?

@iainjack2121 3 года назад

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?

@FerralVideo 2 года назад

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.

@juliejones8785 6 лет назад

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.

@JoshuaBardwell 6 лет назад

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.

@CTPI 6 лет назад

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.

@DennisRiessbeck 6 лет назад

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?

@JoshuaBardwell 6 лет назад

+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.

@DennisRiessbeck 6 лет назад

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

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

@SAFbikes 6 лет назад

what is the bit of piano at the end???

@quadplay2591 6 лет назад

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...

@JoshuaBardwell 6 лет назад

It feels to me like 5 seconds is too long unless you set the threshold to like 15.0. But whatever works for you!

@quadplay2591 6 лет назад

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

I would also like to do some of the cool things on an evolution. Like rssi on osd.

@yonallb 6 лет назад

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.

@mistercohaagen 6 лет назад

@AndyRial 6 лет назад

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.

@JoshuaBardwell 5 лет назад

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.

@asafmagen 5 лет назад

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...

@RETROGAME-FIX 4 года назад

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...

@JoshuaBardwell 4 года назад

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
