Man, thank you so much for UNcomplicating a procedure that I thought I’d never be able to grasp. I’ve watched at least a half dozen videos on setting up ExpressELRS and I thought well here is a purchase that I just made and it’s going to stay in the box. Then I came across your video and said to myself, wow, now this I can do, thanks so much, I really appreciate it.

[@AiOnPoint]

bro you are a legend for making this it really helped!

[@DarrenAllatt]

You are weclome!

[@AiOnPoint]

@@DarrenAllatt thanks again but i just ran into a problem when i go to the tools and try to click the elrs luscript its stuck on loading what do i do? It became really frustarating.

[@DarrenAllatt]

@@AiOnPoint ok so possible issues: - either the internal or external RF module is turned off in the model, so turn on whichever one is ELRS - firmware for the lua script and the firmware on the module are different

[@AiOnPoint]

@@DarrenAllatt yes i have a beta fpv module. So i have internal rf off and external set to crsf. And the open tx firmware is 2.3.15 and i alredy tried to delete the elrs.v3luac and elrs.v3lua file and load one from the configurator but always when i do this the elrs.v3luac file comes back. is this normal? And i dont understand what you mean with that the firmware on the module and on the lua script needs to be the same because i want to get to the lua script page to enable wifi so i can flash the firmware on-this is where i am stuck on a loading page.

[@DarrenAllatt]

What is the version of the firmware on the BetaFPV Module? Update that to v2.5.1 through the ELRS configuration

[@grahamjw75]

I want to add to the others in my appreciation for this video! I have been in this hobby for about seven years now and still cringe when I have to do anything involving the computer side of this, I had just gotten used to crossfire when ELRS came out but like others was excited about the features it offered and got a module that has been gathering dust for a few months because of my fear of comps, I made a pot of coffee and after pausing/restarting your instructional video a 100 times two hours later I am up and running, cannot believe it!! you really do have a knack for explaining things in an easy to understand way, thank you! subbed your channel

[@blackgi]

just got a bunch of ep1 & 2 to setup. this vids gonna help for yr's to come. good job.

[@jeffs3119]

Thank you! You're the only one explaining the transfer of the Lula script and SD card contents. Much appreciated and thorough. Good job of explaining. Subbed

[@MasqUp]

Best ExpressLRS video so far! (I've watched a lot of them). Awesome! Thank you for all your time and efforts in putting out this video!

[@p8jimenez]

This is the video that I was looking for long time ago, thanks !

[@DarrenAllatt]

Glad I could help!

[@firstnamemike]

The best tutorial on KZbin for this.

[@Aaron_Lasher]

Finally!!! Dude you helped me so much Thankyou

[@ChristKrew-Rev1.8]

Thank you!!!! Helped out a lot! For our new TX16s we just needed to update the radio in Companion, download lua and that was it. Worked flawlessly.... ready for winter with our new elrs mobula 6's. Our new radio's would not let us us download the sd card data due in part to not having enough space. Still new to this stuff but this was by far the easiest with both happy model products.

[@DarrenAllatt]

You may need a bigger SD card

[@ChristKrew-Rev1.8]

@@DarrenAllatt yup... just happy that we have our elrs mob6's flying. Can work on that later.

[@ClareFPV]

Great video Darren. Amazing tips.

[@RCBK58]

I really enjoyed the tutorial and was really looking for 900mhz and went to an open field to give 2.4ghz a run w/same setting as demonstrated on the radio and not sure I need 900mhz anymore. Thanks!

[@DarrenAllatt]

Glad to help. The tutorial would cover both ad you are just using a different module

[@beefybeef1326]

Really happy i found this awesome , easy to follow video. New subscriber!

[@DarrenAllatt]

Thank you 🙏

[@beefybeef1326]

@@DarrenAllatt are there any expressLRS modules that have bluetooth built in like the full size crossfire tx module? I would like bluetooth so i can connect to a tablet / phone to the module and download telemetry to see position of the craft on a map while doing long range missions.

[@DarrenAllatt]

@@beefybeef1326 yes all the ESP based TX modules have Bluetooth. Not sure if that functionality of the Bluetooth radio is a feature yet

[@beefybeef1326]

@@DarrenAllatt thanks for the information. I have seen people do it with the crossfire modules. Hopefully it can be a feature in future for the ELRS modules

[@Twinaviation1]

Hi Darren, Great video. Quick question. I do have Radio Master tx16S MKII ELRS. In your opnion what would be best ELRS receiver that will work and bind with this radio? Thanks

[@tombusby2333]

Nice clear explanation. I am having an issue where my RM TX12 wants to use channel 8 for Aux1 , or Aux4 in BF Modes page, for Arm/Disarm. What do I need to change to get my channels to act the same as all of my other drones. I am struggling to fly the drone with limited switch settings and a strange arm switch

[@DarrenAllatt]

Inputs page on your radio just needs to be your sticks, leave the switches off. Go to mixed page and make sure Ch1 to Ch4 is your sticks, then CH5 to be arming switch. Make sure channel map in Betaflight is sticks1234 Sticks can be AETR, or whatever the order is on your mixes page, mine is ATER

[@chrissorlie5291]

Duh! I got it!!! Well I am 72 years old. Still ......... ! Thanks

[@angrypepper3325]

I’m 57, great to read that you’re into fpv at your young age. SEND IT!!!

[@alematik]

Hi! How are you? Nice video!. but, what about the R9M Lite (frsky module) por the X9 Lite? What do you think? I've searched on yt but nothing abount ERLS on R9M Lite module (its an option on the configurator.. but i wanted to see what happened to others). Thanksssssssssss

[@DarrenAllatt]

Hey I don’t do 900mhz, and most people are running 2.4ghz. I’d check the ExpressLRS website for a tutorial

[@LongTail8443]

Oh my god, it wasn't easy like it looks. What I'm I doing!

[@ashfaquezskv4558]

Where did u get the sd synchronisation option?

[@DarrenAllatt]

In the configurator

[@ashfaquezskv4558]

@@DarrenAllatt got it thanks 👍

[@adrianau4246]

my ltm ratio is set at 1:128 is that okay or should i change that to 1:32

[@DarrenAllatt]

It depends on what refresh rate you are running. For 250hz go with 1:16 or 1:32

[@manski209]

Great video, easy to understand. Do you have a video on how to change to Edge TX on an frsky X9 Lite?

[@DarrenAllatt]

No I dont, but the instruction guide on the EdgeTX website is really easy to follow

[@manski209]

@@DarrenAllatt Ok, thank you.

[@parker1ray]

Daren, I have a problem with the script, the display reads loading???/? and does not change. I noticed that the happy model ES24TX lights but in red. I am not sure what is wrong. Does anyone have any ideas. I do have the internal module turned off and the external set to CRSF. I also set the BAUD rate to its lowest possible setting.

[@DarrenAllatt]

What version of ELRS are you using?

[@parker1ray]

@@DarrenAllatt 1.3.2

[@parker1ray]

I have all the latest OpenTX and the newest ELRS configurator. I think the problem is with the Happy Model TX24 module. I was thinking of purchasing another module like the BetaFPV. Are there any that are more plug and play as apposed to Happy Model? I know that Happy Model does sell some pure garbage!

[@DarrenAllatt]

@@parker1ray and which version of the ELRS LUA Script are you using? The latest V2 or the original?

[@DarrenAllatt]

@@parker1ray question. How are the jumper pins on the module? Are both they fully to the right? Example this picture - www.expresslrs.org/2.0/assets/images/Jumper-Lite.jpg If they are not fully to the right for “normal operation” it won’t work. BetaFPV have a slim module. The HappyModel one is actually very solid. I haven’t had any issues.

[@keeemdarrel]

Hi. Can I use ExpressLRS with TBS Tango 1? Thank you

[@DarrenAllatt]

Yes you should be able to because it has a JR module bay at the back.

[@keeemdarrel]

@@DarrenAllatt even though it doesn't have opentx software? I'm sorry I'm just starting with this hobby, I bought an old tango 1 to start with the sim, and I decided that I want ELRS because of the price and the options.

[@DarrenAllatt]

@@keeemdarrel I have ELRS running on a TBS Mambo. In theory it should work with the Tango 1 because the requirement is to be able to run Crossfire protocol

[@keeemdarrel]

@@DarrenAllatt Thank you so much! Cheers.

[@adrianau4246]

So since I used OpenTX 2.3.14 that means I don’t have the nightly builds on right? I have the preset one?

[@DarrenAllatt]

Correct

I have an old p.c. The .exe file won't download. Do I need a new computer?

[@DarrenAllatt]

That’s probably something more to do with your web browser rather than your computer.

@@DarrenAllatt Thanks!! Actually it was the computer operator doing something pretty stupid. Really stupid. Thank you very much for touching base.

Hopefully we can use it on the tango 2

[@DarrenAllatt]

Yes. Tango 2 and Mambo is compatible with ELRS. Different video though

[@nikotttin]

I can indeed confirm: it works very well on the tango2 😉 The setup is very much the same as on the QX7, but with a slim adapter.

[@keeemdarrel]

@@DarrenAllatt Hi Can I use it in tango 1?
