The Radiomaster MT12 is a brand new type of radio the runs opensoure EDGE TX operating system. It is also the first surface radio to utilise a multiprotocol module meaning it should control ANY receiver you have, regardless of brand, hobby grade or toy
This article will be a little different from others I've written - I wanted to share some of the key details of the new MT12 transmitter from Radiomaster before I complete a comprehensive review where I delve into the complex EDGE TX operating system and detailing all of the recievers it can control. The focus here will be to give you an overview because this is quite a step change in what we have seen from remotes previously
As I've mentioned, Radiomaster as a manufacturer are relatively unknown at any level in the RC car world. By contrast they largely own the competitive drone and fixed wing market where a strong mix of quality and value have made them a leader with regular innovative radio releases. I'm excited to see them in the RC car space for the quality/value they bring but it's the technology that I'm most excited about here, namely the EdgeTX operating system and more importantly it's ability to run a multiprotocol module.
What is EdgeTX?
EdgeTX is an open source operating system that itself has evolved from OPENTX. These operating systems were dominant across multiple manufacturers for stick radios as used for quads, helis and planes due to the immense amount of adjustments that can be made. With this much power comes a lot of menus and complex navigation and this can be daunting for a new user but it worth it. I'll detail more when I come to the full review and will work through different model setups. With EdgeTX comes the ability to run multiprotocol and other modules as well...
What is a Multiprotocol module?
A radio protocol is the specific electronic "language" used when transmitter talks to a receiver (and back again in the case of telemmetry). For example, DumboRC, WLToys, HBX, MJX, Futaba, Sanwa, Flysky all have unique protocols and cannot be inter-paired. A multiprotocol transmitter module does pretty much what you were hoping - it can control all of these different receivers from one remote. Basically you set up a model entry on the MT12 for each car and during the transmitter setup for each choose the protocol in the menu that aligns with the car you want to control. From my experience with drones you can even use it to control toys. I have been waiting years to see this in a surface transmitter! 4in1 multiprotocol is an opensource project that is regularly updated with new protocols as the become available, the github page is here: https://github.com/pascallanger/DIY-Multiprotocol-TX-Module
What is the actual transmitter like?
Check out the pics below. It looks plasticky.... because it's made of plastic. In hand though it's well made and sturdy though as surprisingly heavy. Buttons, switches and POTs all have a good feel and this is consistent with the stick radios they make. Wheel and triggers use hall effect sensors. I won't go into detail here but they make for smoother action with no electrical wear parts like potentiometers. Feature set is very strong too but check out the photos for more...
The controller has several addressable RGB LEDS built in too if you think all that black plastic is a bit boring
Thanks for checking out my preview on the RadioMaster MT12 surface radio. I'll place a link below when my main review is finished but this is definitely shaping up to be a gamechanger of a radio. For now, check out my facebook group for more detail or the product page below
