OpenTx Tutorial • How-to use Global Functions • Radiomaster TX16s • [Beginners]

This OpenTx tutorial from rcvideoreviews.com shows how to utilize the OpenTx Global Functions. First I review a handful of Global Functions I've found useful over a 5 year span using OpenTx and then I briefly cover additional options available in the software.

Great video, being new to opentx comes with with a lot to learn. A lot of this I learned already but you have just taught me something I was trying to figure out! How to not get the play track for every switch on startup. It’s people like you that make opentx fun to learn thank you.

[@RCVideoReviews]

Awesome! Always nice to know the work I put into this material helps people out. Since you left such a nice comment, I'm going to give you a pro tip that I'll cover in the next OpenTx video: Under Radio Setup (gear icon) near the very bottom of the page there's an option called "Play delay (sw. mid pos)" I have mine set to 190ms. What that does is delays playing of a track for a switch position for that period of time. Here's the idea: Say you have high, mid, low rates on SB like I do and you flip from High to Low. You don't need to hear the radio call out the mid position because you skipped over mid. By using that delay if you move the switch before the 190ms is up, the radio won't play the middle track. That's just another example of the granularity they provide on OpenTx. It's been very fun to watch this software evolve. Anyway, welcome to the channel. Make sure you sub and hit the notification bell so you know when I post other OpenTx vids. J

[@FASTFREDDIE-R.C.]

RC Video Reviews unbelievable it’s like you read my mind about what I want to change but haven’t learned yet. I’ve been looking for videos for this type of information but nobody does videos for the little things like this it’s always full on geek which doesn’t help the newbies. Thank you again!!!

Hi. I really like your video's. You explain everything in a simple way. I already fly RC planes and drive RC cars for over 50 years...But you need to go with the time right? Since I am also a sound engineer, musician as hobby and retired industrial engineer I see a lot of things in common of the settings and setup of the tx16s when I compare it with digital audio mixers or prorammable industrial sensors,encoders, frequency motor controllers, stages and bus control systems. I just bought a tx16s mark 2 max and while I am waiting for it to arrive I already want to learn everything how to set up and edit the transmitter and how to set up my planes. Your video tutorials make that a lot more easy.. Thanks and keep up the good work...And don't crash!....Hahaha. Greetings Herman from the Netherlands (near Amsterdam)

[@hermantelbo6283]

Funny..I remember I build an ugly stick just from a German magazine called FLUG about 40 years ago from balsa wood and put a os max 40 on it....Was a good plane until my 27mhz Robbe transmitter had problems...probably because of an illegal hobby Am Radio amateur what caused a lot of interference on RC model control systems those days...pff...We also needed to wait for each other if we had the same crystal so the same frequency. because we only had limited amounts of channels available. this stayed also later with the 35mhz for planes and 40mhz for cars boates and sometimes planes and helicopters. Yep a lot changed in 40 years with open tx systems...Much better..But somehow I miss the old days...But that's because in my opinion its because people changed and to many gouvernement rules now...

Good luck with your radio. When you invest the time to learn the core functionality, the rest of it becomes quite easy.

[@RCVideoReviews]

Sounds like something wrong with the location or permissions of the SOUNDS folder on your SD card. I would probably delete it and copy the SOUNDS folder from the SD Card contents.zip file back over to the SD card. If the sounds are there and permissions are correct, the radio will find them.

[@upperechelon3456]

Hi Thanks for the super videos -rally helpful. I have used global functions as described in the video to reset timer1.

I have been procrastinating on learning global functions. Thanks a bunch. I know you showed openTX . Do you have a video on EdheTX GF. My global functions are significantly different. When I choose GF1, I get drop down lists, and the function list is limited. No throcut or flaps etc.

[@RCVideoReviews]

Global functions on EdgeTX and OpenTX are pretty much the same. There may be a few new ones on EdgeTX. Special Functions and Global Functions are not identical. When there are potential negative implications of setting a feature as globally available, decisions were made to remove it. So if it's not in the GF list, you'll have to set it as a SF.

I think the LUA Script from Special Functions need to be function scripts in that folder.

I'm trying to implement some of the Global Functions that you outlined in this video, but I've run into a couple of obstacles. 1) The S1 and S2 rotating pots don't seem to show up in the list of available switches and 2) When I try to assign a switch to Play a Track, none of the .wav audio files show up under the parameters column. I just see four little dots. I checked, and those .wav files are present in the English folder of the Sounds folder. Any thoughts? Thanks for a great video series!

[@RCVideoReviews]

The pots are not available in the first column, but they are available in the 4th column. Do this on a blank GF Line: 1) SA down 2) Volume 3) Press Jog Dial and release. Cursor should blink. Spin S1 or S2. That should set S1 or S2 as the volume control for the radio. It shouldn't be "English" it should be "en". The path should be: /SOUNDS/en/ The first file in that path shoul dbe 1cell.wav if you're using Amber. If you see that in your SD browser, long press on it and the popup should offer a play option. Hit play. If that works, then you should see the wav options in your drop downs.

Hey John, I got my TX16S a couple of month ago and started by viewing your beginner videos and I feel I have come a long way in setting some advanced features in my radion thanks to you. I have one thing that you might know off and that is using Global Functions for settings used in all models in stead of Special Functions. The the Logical switches are available in Special Functions but not in the Global Functions. Is that a missing feature that is know? I found a way around by creating the new function in Special Functions and copy the new function to Global Functions. The software version on my radio is the 2.3.9. All my programming is done on the Radio. Thanks for all your effort doing great tutorials.

[@RCVideoReviews]

There are a number of Special Functions operations not available in Global Functions including things like Channel Overrides. It's been like that in OTX as long as I've been using it. I doubt it's overlooked/unknown. "I found a way around by creating the new function in Special Functions and copy the new function to Global Functions" How are you copying a Special Function to Global Functions? In any event, I'm happy to hear the videos have helped out out. Thanks for the comment.

[@tommimadsen3719]

I use the traditional method by long press a Special Function and select copy. Open the Global Functions and long press and select paste. I am sure you already know that :) I have encountered the same issue with your Throttle Override. It is not possible to copy a channel override. Thanks for your reply and I will be watching for more OTX videos.

[@RCVideoReviews]

@@tommimadsen3719 I know about copy and paste, but I've never tried to copy a function that exists in special functions to a global function where that "function" doesn't exist. I will try it to see what I learn, but that doesn't sound right to me. I'd be surprised if the radio allowed that.

[@RCVideoReviews]

That does not work on my radio. Here's the test I just ran: 1) Special Function 1 - SH down, Override Ch3 - 100 On. 2) Copy SF1 3) Exit model, press system, page to Global Functions. 4) Highlight GF5 (empty) 5) Long press jog dial, no pop-up menu. 6) Short press jog dial to edit GF5, pop-up says "Switches, Trims, Other, Invert" Selecting other populates field with "ON" I cannot copy functions from Special Functions to Global functions when the function doesn't already exist in Global Functions. Test 2: 1) Special Function 1 - SH down, SetFailsafe, On 2) Copy SF1 3) Exit model, press system, page to Global Functions. 4) Highlight GF5 (empty) 5) Long press jog dial. Menu pops up with Paste option. 6) Short press jog dial, SF1 pasted into GF5. SetFailsafe is the function in question and that function is already available in Global Functions.
