Tekin RX4 Hardbox Waterproof Sensored/Sensorless D2 Crawler ESC
I put this plus a ROC412HD 1800KV motor into my heavily modified TRX-4, and the performance is awesome. It's just like the 3 RX8 Gen 3's that I have in my Tekno rigs, only it's a sweet crawling setup...

Tekin RX4 Hardbox Waterproof Sensored/Sensorless D2 Crawler ESC
Great ESC! Previously had a castle mamba x (horrible esc) and then it burnt out at axialfest. Bought my RX4 and couldn't be happier
