A: The MT12 is powered by EdgeTX, an open-source operating system. Please enjoy the unprecedented level of customization, mixing, and flight-controller-grade logic now available for cars and boats.

Q: Should I choose the ExpressLRS (ELRS) or the 4-in-1 version?

A: Please choose ELRS for ultra-low latency and extreme long-range performance. Choose the 4-in-1 version if you need to bind to existing receivers from brands like Futaba, Spektrum, or FrSky.

A: As standard, it supports 16 channels. Please note that the 4-in-1 version can be expanded up to 32 channels with an additional external module for heavy equipment or complex scale builds.

Q: How do I power the MT12, and are batteries included?

A: Batteries are not included. Please use either 2x 18650 Li-ion cells or a 2S 7.4V 5000mAh LiPo pack. The oversized battery compartment provides plenty of room for long sessions.

Q: Does the MT12 support fast charging for quick pit stops?

A: Yes, it supports QC3.0 fast charging via the USB-C port. Please find that it can pull up to 2.0A, allowing you to refill your power quickly between races.

Q: Is there an external module bay for different RF systems?

A: Yes, it features a Nano-size module bay. Please feel free to install a TBS Crossfire Nano or a RadioMaster Ranger Nano if you wish to expand your connectivity options.

Q: Can I customize the physical switches and joysticks?

A: Yes! The MT12 features customizable base switches and a 4-way joystick. Please tailor the ergonomics to suit your specific driving style or model requirements.

Q: What receiver is included with the ExpressLRS version?

A: It typically comes with the ER3C-i PWM receiver. Please note this receiver features a built-in ceramic antenna for a compact, clean installation in your vehicle.

Q: How do I update the firmware on the MT12?

A: You can update easily via the USB-C port or by using the SD card. Please keep your EdgeTX and RF firmware updated to access the latest features and model protocols.

Q: Does the MT12 provide telemetry data like battery voltage?

A: Yes, it does. Please enjoy real-time telemetry updates. For example, the included ER3C-i receiver can detect battery voltage ranging from 4.0V to 35V.
