MRT mPTX Pro Transponder: The RC Racing Transponder Serious Competitors Trust
If you have ever lost a race because your lap times did not register, you already know how much a reliable transponder matters. The MRT mPTX Pro Transponder is the unit serious RC racers reach for when consistency is non-negotiable.
Why the MRT mPTX Pro Stands Out
Built for 1/10 and 1/12 scale competition, the mPTX Pro delivers fast, accurate signal transmission every single lap. It reads cleanly through the timing loop whether you are running carpet or asphalt, and it does not skip a beat when the racing gets tight and cars are stacked through the infield.
That kind of dependability is what separates a podium finish from a frustrating day at the track. If you are competing at a club race or a sanctioned regional event, your transponder needs to work every time — and the mPTX Pro does exactly that.
Compact, Lightweight, and Easy to Mount
The mPTX Pro is engineered with a compact form factor that fits cleanly into tight chassis layouts without compromising balance or ground clearance. At just 30 grams, it adds virtually no meaningful weight to your build. Setup is straightforward, and it is fully compatible with MRT timing systems used at clubs and sanctioned events across North America.

Who Is the mPTX Pro For?

Whether you are chasing a personal best at your local club or running at a regional championship, this transponder gives you one less thing to worry about. Your laps count — every one of them.
