never mind i figured it out. you have to use the configurator.

There are other issues with the configurator, so please use a web flasher if possible.

Please refer to the following when using the configurator.

Hello guys, I just got this radio. Multi version LBT.

I am a bit lost so if someone can help me out I'd be much obliged.

I am aware the radio has a learning curve, however, even after watching many Youtube videos, I've found something different in mine.

In my internal RF options, after picking "multi" I don't have nearly as many protocols as I see people having. I have about 8.

I thought that could be related with the LBT version but I've seen people with the LBT version still having more protocols than mine. I want to try some out of the box bindings like WL-toys, Mini-Z, but I don't see the protocols for those.

1-does anyone have any clue why is that?
2-can I reflash my radio so it is FCC instead of LBT? And does that mine flashing the multimodule or EdgeTX firmware, or both?
3-EdgeTX buddy doesn't show MT12, what radio should I pick from the dropdown menu?

Thank you.

1-I don't understand what's going on.

2-Multi-module flash and EdgeTX flash are completely different things. What you need this time is a multi-module flash.
The original SD card contains some multi-module firmware from the beginning. SYS>SD CARD>FIRMWARE>Press and hold the desired firmware.bin>Flash Int. Multi. You can easily flash it with this, so you may want to try various things.

3-MT12 is supported from EdgeTX2.10. In other words, it is currently not officially supported, so it does not appear in the EdgeTX Buddy list. The latest version can be downloaded from here. Although it is not a stable version, many fixes have already been made, so please update at your own risk.

Thank you.

After updating EdgeTX, and then flashing the multi-module with the latest firmware file that does not say LBT, all the protocols popped up now. Works beautifully.

Cheers!

Anyone know how to adjust the servo frequency (if you can) on the MT12? I couldn't find it in the menu.

First impressions of the radio are that it has linear controls out of the box, very smooth physical movements with the hall sensors. I did not seem as "connected" or in tune with the car as my Sanwa MT-44, but that may be due to some radio configuration issues. I'm running ELRS.

Receiver is actually slightly too small, not enough space between the plugs IMO, like needs another 0.1mm between them.

Servo frequency is set on the RX. (It might be available through the ELRS LUA. This is the method I know)

With the TX off, power on RX
Wait 60 seconds for it to go into wifi mode. (led changes to fast blink)
connect to ExpressLRS Wifi wireless network from computer/phone. password is expresslrs
go to http://10.0.0.1/

Servo outputs are under options.

full instructions are here: https://www.expresslrs.org/quick-start/webui/

sorry didnt see you already posted a reply how to.

This is terrific feedback thanks for sharing. Please report back if you’re able to make changes that result in a more “connected” feel, whether from servo frequency or other programming changes to the channel functions.

change the packet rate to f1000k on the tx.

When this problem occurs, receiver will hold the last state for 10 seconds.
In my case, I lost control on the straight at maximum speed and crashed into a fence at full throttle.
I can't say for sure, but in my testing, the problem does not occur with 3.3.0. I recommend using 3.3.0 until the cause is determined and the bug is fixed.

flashed to 3.3.0 and that fixed the problem. no more lost connection.

I reported it to an issue on Github, but it seems that the developer has not responded to it yet.
I think the developer will take action if many users report the problem, so please feel free to post your trouble experiences to #2548.
I think this thread is also a good place to post.

I thought the packet rate from TX to RX was different to the PWM from RX to servo.

it is. but that could also effect that "connected feel".
