EdgeTX Easy Wireless Trainer Setup for Everybody with DSM, AFHDS2, and D16 

Great help, you really give very clear instructions on how to get the most out of Radiomaster radios.

Very useful and well explained. The fact it can be done with a radio like a Spektrum is really fantastic.

I think a key difference between channel and stick is that with sticks, the student radio does not have to have model specific information as it effects the inputs on the master radio. Channel on the other hand bypasses the mixes on the master radio and the channels received are copied to the masters TX. There is a way for you to get the extra channels when using Sticks trainer mode. For both the Input and Mix screens, you can select any trainer input channel as a source for any input/mix. They are labeled "TR" followed by the channel number. So TR1 is student channel 1, TR5 is student channel 5, ... I think the TR sources always provide the student channels in case you were using that for controlling a camera pan/tilt or other such functionality so use activation switch when adding to mix/input. I prefer to use sticks so my trainer radio does not need to have model specific config.

Nice job John. Very informative snippet. Since I got into rc airplanes a few years ago, I struggled when I went with a Radiomaster 16S. You have been a great resource to learn everything I need to know about programing the radio. Keep up the good work.

This is really a great feature. I hope that it will be possible in the future to do the same thing with ELRS. Ie having a student radio with ELRS and using an ELRS external module.

Ps if you have upgraded your radio from open TX to edge TX make sure you upgrade your internal module RU-vid video Module update recommended. How to flash radio master TX 16 Multi protocol module in edge TX posted May 2, 2022 Once again you’re the man. Cannot thank you enough.

You are the man! This is awesome!

Great video! Thanks!

Very useful. Thank you.

great job, thank you

that's cool, thanks

Awesome. I was gonna work on doing this for a RC car. I've been using my TX16 to drive the car because I have ERLS on it but it's hard to control. So I've been wanting to hook up a RC car controller as a trainer and keep the express ERLS

Thank you SO much! You have just solved my only reticence with moving to the Radiomaster TX-16s: The ability to train others wirelessly with Spektrum. This is why I am happy to support you as a Patreon...you multiply my equipment investment value exponentially, as I would NEVER be able to figure this stuff out in a lifetime! I'm sure that this will not be as simple as you made it look but looking forward to the challenge. Two requests, though: 1) Can you make a Spektrum-specific quick video, since there are so many of us converts from Spektrum, and 2) Are your trainer plane STL files available somewhere? that is a VERY cool training/learning aid that you have there. Just brilliant stuff!👍👍👍👍

I have DSM in the list But I do not have DSMRX on the list?

For other folks like me who came over from spektrum, it should be noted that you can pair the tx16s to a dx8g2 without the need for a second tx module in the bay of the tx16s. The gen2 spekys contain an rx and tx that function simultaneously. However, the speky has to be the master and you will have to let the student handle your tx16s 😞

Can you show how to get more than 4 channels in Trainer mode??

Interesting that you noticed frsky trainer signal lost issues. I see that as well at the field. I have a TX16 mk1 and the trainer port is useless as well. Going to try using a student flysky tramsmitter...

Thank you for this and your older video on the same topic (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iiZehq3aS2A.html) - between the two I was able to get my TX16s working in buddy box mode with an old Spektrum (E-flite) MLP6DSM. I wanted to share a headache that had me confused for a while. In your other video, you off-handedly mentioned using the internal 4-in-1 module as the receiver, until trying that all of my binding attempts had failed using the external module as the RX. All of the documentation suggests this doesn't matter, so I think the issue has more to do with the antenna position, using the same protocol for both (DSM) and possible receiver de-sense (overloading). Keeping that in mind, low power mode also may have helped overcome this. You mentioned some issues that you thought had to do with being too close, I'm curious if spacing the radios out resolves this or if it's the proximity of the *modules* that is the issue. I'm going to try running a coax cable to get one antenna further away. The other big thing I noticed is the latency. The "Student" controller experiences notable latency in the controls that isn't there on the Master. I'm curious if this is less of an issue with something like ELRS or another protocol. I've found complaints about Spektrum Buddy Box mode having high latency even in official Spektrum controllers with cable.

Great job, John!!! Question: If I'm using two TX16S radios, do I have to have the external module?

Thanks for the great video. Is there a possibility to use the Expo settings of the Master transmitter? instead of the Student? I have connected a joystick to my transmitter as a student, but it has no Expo setting options.

thanks for video. i want to ask if i have two different radio but all edge TX, such as TX16S and pocket , can i use the trainer mode,thank you

hi all, has anyone else had issues with one module nocking out the other one. I have a tx16s 4 in1 connected as multi/trainer to a student Radiomaster pocket. I have a Elrs module in the JR bay but as soon as there are both active I loose the trainer controls. i have tried different rx protocols which has slightly differnet effects like constant trianer recovered to trainer lost. Thanks

For some reason, my signal from the trainer transmitter is super laggy and keeps on jumping around, making it unflyable. do you know how to fix this? I have a T antenna on my external multi module, and am using my internal ELRS to communicate with the model.

And it keep flashing Module update recommended?

Awesome work, here. Looks like I won't need to throw my old Spektrum DX7S out after all. I'm gonna go ahead & bench test this setup where my DX7S is the Student's Controller & the Instructor's Controller is my RadioMaster TX16S Max Edition, & see how that turns out. =^/,..,^=

👍👍👍

Hello John, Really like your trainer mode with the internal module it works perfect with the FrySky Xlite and a TS16S. But can you use it with the pan and tilt together on trainer mode so you can flight together. I use the headtracker project with the Arduino Nano 33 BLE. Can you run 2 trainers ad the same time or is there another option to use both.

FS2A_RX works terrible! Specially with my Turnigy EVO

Can you use a Spectrum transmitter as a trainer with the TX 16S as master

Hello . . .I have a question that I've been struggling with for a couple of days . . . . Can this be used to set up multiple models ?? So that a student can fly 2 or 3 different models using this method?? ie. can you have 2 or 3 models set up on the student transmitter and have them all binding to the same TX16S (that's set up in RX mode ?? ).... Thanks . .

Well, copied all this and used the external 4 in 1 module as my DSM- RX Trainer transmitter for the master. The external transmitter module will not bind the other TX16S internal 4 in 1 module on DSMX auto? Any ideas?

Work with all the tx16s? Or only mark ll?

I have a Multiprotocol module on my FrSky X-Lite Pro, which is on OpenTX 2.3.15 ,but I can't select Master/Multi in the Trainer Mode selection. Is this only available on EdgeTX?

This is awesome ! Can this be done automatically? I mean, if master centered the stick then it will use student channel, if master move the stick then student will be ignored, will be quicker in case of emergency but of course after using a switch to activate the trainer.

I don't have the Trainer Option shown in 4:20.

I can connect a second transmitter to my tx16s via DSM_RX, however I also only have dsm receiver in my model. Unfortunately, my tx16s has an internal CSRF protocol, so I cannot communicate with the model. Is there any way to receive and transmit via my multi module at the same time?

Q : is there anyway you could have the trainer having a switch to control who's flying the model ? As my friend I'm teaching likes to fly with his own transmitter and drone THANK'S ...

Does the version of edge matter ?
