Radiomaster
RadioMaster builds open-standard radio controllers trusted by RC pilots, drone racers, and increasingly by combat robotics builders who demand precise, reliable control in the arena. Based on EdgeTX open-source firmware and ExpressLRS RF technology, RadioMaster radios give builders full control over their setup — without locking them into a proprietary ecosystem.
For combat robotics, the RadioMaster MT12 is the standout choice. Unlike traditional stick-based transmitters, the MT12 uses a pistol-grip wheel-and-trigger layout that maps naturally to ground vehicle control — the trigger governs speed, the wheel governs direction. Experienced builders know that stick controllers can introduce unintended steering inputs when you think you're driving straight; the MT12's ergonomics eliminate that problem and keep your bot going exactly where you intend.
The MT12 also features on-device programming via EdgeTX — no laptop, no cable, no separate configuration software needed. Once you've outgrown a pre-programmed controller like the FingerTech T6, the MT12 lets you tune drive modes, set global variables, and dial in your control response directly on the radio. For builders who compete seriously, that flexibility can make a real difference in the arena.
ItGresa Robotics carries the RadioMaster MT12 ELRS because our own builders use it and trust it. If you're ready to step up your driving game, this is the radio that grows with you.
