MRT mPTX Pro Transponder

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 is the transponder serious RC racers reach for when consistency is non negotiable.

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.

The unit is compact and lightweight, so mounting it does not compromise your chassis balance or clearance. Setup is straightforward and it is compatible with MRT timing systems used at clubs and sanctioned events across North America.

What you get with the mPTX Pro:

Accurate lap time registration on every pass through the timing loop Compact form factor that fits cleanly in tight chassis layouts Lightweight construction with no meaningful impact on handling Broad compatibility with MRT timing infrastructure Durable build quality that holds up through crashes and repeated use

Whether you are chasing a personal best or competing at a regional event, the mPTX Pro gives you one less thing to worry about. Your laps count. Every one of them.
