BINDING DIFFERENT RECEIVERS TUTORIAL | EDGETX | MT12 [EN]

[@bugman72]

One thing to note on the MT12...for surface vehicles you need to go into the Radio Setup page and change the default channels from "TS" to "ST". If you don't, every new model you create will have steering on Channel 2 and throttle on Channel 1. After doing this, any new model you create will have proper channel assignment for a surface vehicle ("1 to turn, 2 to burn"). I hope that more surface protocols get added to the MPM soon. Will be very nice to have one radio for all of my vehicles. Unfortunately, one protocol will not be available with the internal module. Flysky's ANT protocol is not compatible with the RF chip that is in the MPM. Most of the new smaller scale RTRs (Axial SCX24 V2, Furitek, Hobby Plus, FMS).

[@arminrc]

Thanks for the great comment! You are right, the ANT protocol is really missing (and so are the Sanwa protocols). May be the come later. Lets hope for the best.

Nice video showing different receivers which other people doing reviews didn't get

[@arminrc]

Thanks for watching! For me it is important to show different setups in order for the viewers/users to make a decission if the MT12 is right for them.

[@hectorperriere5504]

Well, thanks for providing a new tip regarding my problem, even more so since you no longer use the FS brand, and especially because you are not on my payroll, (the payroll thing is a joke), finally your videos are very good, I have seen them all and I have learned a lot, thanks for taking the time to educate ignorant people like me, greetings

Hi Armin, a nice RadioMaster system. Great explanation. Hope you and the family have a happy New Year 🎉🍾🎉

[@arminrc]

Thank you so much! The MT12 is a very versatile radio and gives you a lot of options when it comes to receivers, programming, etc. All the best to you and a happy new year to you and your beloved!

[@bugman72]

It's also a bit disappointing that the Radiomaster receivers have the issue with cutting out when the Tx and Rx are too close. Was planning to use the included Radiomaster Rx in my SCX24 comp rig, but had issues when testing on our indoor course. On an indoor, elevated course I found myself being too close to the vehicle when trying to navigate an obstacle. Signal would cut out until I backed up. Ended up taking that Rx out and throwing in an old Axial AX-3 Flysky-compatible Rx due to its relatively small size.

[@arminrc]

That's indeed a shame! In the good old days it was a problem if you where too far from the car and nowadays it is a problem if you are too close. Strange new world!🤨

[@ronmartin7253]

I just found this out on race day. Returning to amain as defective and going to a real radio brand. thanks radiomaster for a wasting my a time

[@DaejiGalbi]

Hi, I've watched your other videos and they are really helpful! thank you! For this one, I am struggling to find any information on my receiver to use it to bind to the MT12. So I have some complete sets with receivers and they are aparently from Carson, which includes following names: Carson Reflex Wheel Start, Carson Reflex Wheel X Do you happen to know how I can bind those? The included RC85C works fine when I follow the video. Thank you!

[@arminrc]

Sorry, but this is the problem with this radio systems. No info about the used protocol. You could test the FlySky AFHDS2A protocol. Maybe it works. Sometime the receivers are just re-branded versions of the same receiver from another brand. Maybe you are lucky and find such a "duplicate" with more infos about the used protocol. I know that is little consolation, but I have kicked out all the "cheap" radio systems and replaced them with the MT12 and the right receiver for the right car (usually I use Rx from Radiolink, Spektrum and FrSky). Rx from Radiolink are quite cheap and perform really well (but they are a bit on the larger side).

Bonjour et futaba enR2106GF je voudrais savoir le programme merci encore

Désolé, mais je n'ai pas de récepteur Futaba disponible.

[@hectorperriere5504]

Anyway, I turned my brain on and it is still impossible for the FS-BS6 receiver to work correctly with the Radio Master MT12, I can't find a way, even if I change the steering servo channel to channel 6, the car when turning the left and right wheels, generates an intermittent drive, I hope you find the solution for this problem, thanks

[@arminrc]

Well, first of all, I am not here to find solutions for your problems. As far as I know I am not on your payroll. I am not using FlySky products anymore and that includes the FS-BS6. So I do not have the means to test it out anymore. But, with all that said, the FS-BS6 can control two channels: the first channel (steering) to correct in order to keep the car on a straight line and the second channel (throttle) to reduce throttle when cornering. So, if you use channel 3 for steering and channel 4 for throttle and move the corresponding mixes in the MT12 accordingly, then you should have a working Rx.

[@coyoty41]

Thank you bud

You are welcome!

Just got finished struggling with binding my Spektrum DX5 Pro transmitter to a Spektrum receiver. I noticed you talked about being to close during binding. I had 3 cars act the same weird way when I bound them too close to the radio. The car would work just fine, until you started driving it. It would turn to the right when I started going. Re bound them and this time, went to the next room, and with each car, that method worked. Even had a similar problem with my NX-8 transmitter in my helis! They flew all weird when I bound them too close. I'm wondering if the telemetry would properly display on this radio from the Spektrum receiver?

[@arminrc]

Thanks for the comment! I am glad the video was of some help to you. It is indeed weird that there is a problem if RX and TX are to close together while binding. I have never had this issues with my Spektrum stuff, though.

[@jesseharless24]

How do you use radiolink telemetry on mt12.

[@arminrc]

Not all Radiolink Rx have telemetry. The R7FG for example has a dedicated voltage sensor port and can transmit the voltage back to the Tx. On EdgeTX / the MT12 you can see all the sensors in the telemetry page. Maybe you must do a search for new sensors to the the data.

[@jesseharless24]

@@arminrc tried that I get nothing from radiolink with the telemetry adapter plugged in when I hit find new

[@hagenthehorse7422]

Can i use traxxas recivers with the 4in1 radio?

[@arminrc]

Please check out the supported protocols on multi-module.org. There you will find every information what Rx/protocols are supported. Currently the Rx with the number 6519 is supported.

[@DanPRC]

Hi. I’m the one who asked you about the 10ch Dumbo rx. So it seems that the 4in1 can’t control channels 9 and 10 on the 10ch Dumbo rx. I believe you said that you was going to order this receiver to see things for yourself. I hope you can find a way around this.

[@arminrc]

Right, the Rx is on its way. If I found something I'll let you know.

[@DargoDog]

VERY GOOD VIDEO!!!! I just ordered my MT12 (ELRS with a 4N1 module), and looking forward to what can be done with it. I think I am going to set up a tester board like you did for testing different configurations. One of the key things I want to do with this radio is to set up skid steer, do you have any tips for this?

[@arminrc]

Thanks so much for watching and taking the time to write a comment! Regarding your question about skid steer: would it be ok for you if I anser this in a video? I am about to make one and it should be available within the next days.

[@DargoDog]

@@arminrcA video would be awesome!!!

[@CheapTricks]

Will this transmitter support afhds3?

[@arminrc]

No, it wont! AFHDS and AFHDS2A only!

[@rulyiman7597]

can u bind the elrs version to another receiver?

[@arminrc]

The ELRS version can bind to ELRS receivers. You can add an external 4-in-1 modul to the MT12. Then you have both.

[@rulyiman7597]

@@arminrc ahhhhh got it, thx

[@michaelrajca6043]

great video and great explanation. my question is ,i saw you bind to different brands and i am wondering just how to set the correct protocol and subprotocol for each brand rx. is it listed on the rx? i have a few traxxas and a few spektrum rxs which i would like to bind to 1 radio. setting protocol and subprotocols is my only problem before i purchase this radio.the navigation is pretty straighforward

[@arminrc]

Thanks for watching! In the video I show for every one of the receivers what protocol and sub-protocol are used and how you do this. For your Spektrum Rx it depends on the protocol they use (DSMX, DSM2, DSMR). The Multi-Protocol-Module supports DSM2 (DSMR) and DSMX! For your Traxxas Rx there is the Traxxas protocol. Please check out the list of supported protocols on multi-module.org.

[@michaelrajca6043]

[@arminrc]

@@michaelrajca6043Correction regarding the supported spectrum protocols: DSMR is supported (use protocol DSM)

[@jesseharless24]

Anyone know if the 4 in 1 will bind to a wpl stock electronics crawler?

[@arminrc]

What protocol do they use?

[@jesseharless24]

@arminrc I'm not sure

[@arminrc]

Then it is hard to say if the 4-in-1 module will work with the WPL cars. Check out www.multi-module.org/basics/supported-protocols maybe you find something there but if the manufacturer of such RTR cars does not disclose the used protocol it becomes difficult to decide if the MT12 will work.

[@TJ-rc]

I have a radio link r6f receiver it binds instantly like yours in the video but then nothing works am I missing a something?

[@arminrc]

Well, that is hard to say without further infos. I used at least four different Radiolink Rx with the MT12 without any problems so far.

[@arminrc]

Please double check the connection of the ESC to the Rx. If the polarity is reversed then binding seams to work fine and you even get a signal strength indication on the MT12. But nothing works.

[@TJ-rc]

@@arminrc the polarity turned out to be the issue thanks for following up on that!!

[@yiarkungfu]

I've had this radio since its launch and it's a fail. I love OpenTX but this radio's 4 in 1 protocol wont pair with any of my receivers. I also have the issue where the radio can be too close to the Radiomaster receiver and breaks the connection because of signal overload.

[@arminrc]

Sorry to hear that. But obviously the radio is binding to a lot of Rx, at least my version of the MT12 (and I've heard from others too that they are happy with their MT12's). The close proximity problem of the MT12 is a shame, though, but there are a large number of alternate Rx out there.

[@heady2008]

Which version of the 4 in 1 did you buy? If it's the LBT version then you will have a reduced number of RX protocols that it will bind to.

[@arminrc]

@@heady2008 Thanks for the info. I already did a video about "Missing protocols" but it is in German. Maybe I should do this in English, too!? What do you think? Are more people affected by this "problem"?

[@heady2008]

@@arminrc Maybe a short video explaining the differences between LBT and FCC versions and how to change from LBT to FCC?

[@ronmartin7253]

can someone decipher just binding this to a er3ci or er5ci radiomaster receiver? i just bought this and it does nothing - and, reading that it doesnt bind well if its "too close" makes me realize this might just be a poorly finished product at this early stage.

[@arminrc]

Yes, it is a shame that there is a problem with the Rx and Tx being to close together. Hope Radiomaster can fix this.

[@dhstube]

Works with Spektrum SR receivers?

[@arminrc]

It works with Spektrum DSMX and DSMR receivers.

[@coyoty41]

I see you bind the FlySky FS-BS6 Receiver but you can't turn off the gyro on it the svc do you know how to turn off the gyro.

[@arminrc]

I think this is - currently - not possible. It seems that "configuring" the gyro is some kind of forward programming.

[@shaynejenkins446]

no and it sucks

[@coyoty41]

you are so righ

[@ladrao777]

Can the gyro at least be controlled? Can the gains be set up/down for channels 1 and 2? Can priority be adjusted?

[@arminrc]

Well, it seems that this is currently not possible. The problem is, that every manufacturer can use whatever commands they see fit to control the gyro. For the Radiolink Rx (R6FG for example) you can use channel 8 to "deactivate" it. But for the FlySky Rx there is currently no way to do it. In order to have control over the gyro you would need to know all the commands a FlySky Tx is sending to the gyro. This you can only retrieve with "reverse engineering" and this is a very time consuming process (given that you already have all the needed equipment for this). The best way of using the MT12 is to make sure, that the used receivers do not have a gyro installed (yes, I know this doesn't help if you already have a lot of such Rx).

[@coyoty41]

no it can not be controlled you have no controlle over the gyro

[@arminrc]

You are right. The gyro in the FlySky FS-BS6 cannot be controlled by the MT12. The gyros in the Radiolink Rx (e.g. in the R6FG) can at least be controlled somehow with the P1 pot.
