[@EddieVichta]

Excelent. Thank you very much. One question... I did not find anywhere how to charge battery using usb port... I mean how many VOLTS can or should I connect to usb cable... ?? Normal usb smartphone charger or...? 5 volts...? 9 volts... ? 12 volts..?? No idea. If you can give me that basic info please..? I will appreciate it. Believe or not, I really did not find it anywhere. Even not in original manual...

Charging the MT12 is absolutely painless! Just connect the lower / rear USB-C port to a standad USB charger. You can use an USB-Port of your computer for example or a charger you use with your smartphone. It is highly likely that you already have a charger for the MT12 at your disposal. Please keep in mind, thtat the MT12 does not come with a battery (it comes with a little tray which holds some AA sized batts). I recommonend getting the 5000mAh LiIon battery from Radiomaster. It is a perfect fit to the battery compartment of the MT12. Hope this helps! Have fun with the MT12. It is an amazing radio!

@@arminrc Thank you for reply. I am still not fully sure.... Yes, I have few "standard" smartphone chargers, but... some of them are outputting 5 to 9 volts automatically depends on phone connected. My Samsung for example. For now I use strictly 5V charger only to be safe. Basic and crucial info about charging voltage is missing in the manual. I know, maybe most of people will say "standard" USB-C means 5volts, but it is NOT fully true. Another question is: Can I use my radio connected to charger ? I mean browsing menus, setting models, options etc. while charging? Or radio MUST be off when charging? For example my old HORUS X12S must be strictly OFF when charging. Thanks again for all your help!!! BIG THANK YOU for all series with MT12 radio. Greetings from Ireland !

If I were you I wouldn't worry too much about the charger. If I read the data correctly then the internal charging circuit of the TM12 is QC3.0 "ready". So I guess that every charger that is capable of delivering proper power (at least 2A) can charge the MT12. And yes, you can use the radio while it is being connected to the charger. But I have to admit that I do not really know if the radio is actually charging while you use it. I guess I have to test this when the battery is more empty. Ah, and by the way, I made a mistake in an earlier comment I made. The included battery tray does not take AA sized batts but 18650 sized ones.

Hi. I have a question. Hopefully you can help me out. Im trying to connect my headtracker to the aux/sbus port on the side. But I dont see the option for SbusTrainer in the Serial Section of the Hardware page. Do you know what I can do to get this to work? It does work through ppm/dsc port, but I want to use the aux port since the installation is much cleaner with only one plug and sbus is faster than ppm. Any help is appreciated. Thank You

Well, I guess currently you are out of luck here! It seems that the MT12 is not yet fully supported by EdgeTX. On the EdgeTX website it says: "RadioMaster MT12 (Planned 2.10 for full support)". The firmware that is available for download is the exact same as the one already installed on my MT12. So maybe the feature you are asking for is coming to the MT12 with a later firmware version.
