mike Verified Owner Tuesday, Sep 22 2020 (about 5 years ago) Tekin RX4 Hardbox Waterproof Sensored/Sensorless D2 Crawler ESC I bought this RX4 and connected it to a ROC412 3000KV motor and a 3S lipo battery. I also connected a hotwire 3 box to it. So far i like my mamba x better for low speed control. Using the same motor i cant get the low speed start up to be as smooth as the Mamba X. This ESC seems like it would be better for bashing than crawling. 4 customers found this review helpful. Timothy Powell Verified Owner Thursday, Dec 17 2020 (about 4 years ago) Tekin RX4 Hardbox Waterproof Sensored/Sensorless D2 Crawler ESC Finally finished a TF2 with my r 4. Worth the money and more. With the Hotwire 3.0, program if was too easy. Took it out in our first descent snow, no fender wells, the entire chassis was layered in anout 3 in his of snow by the end. Rx4 with a sensors roc 412 was just fine. Even after I let it dry over warm air and water drained all over it it was just fine. Won’t put anything else in my future off road projects. 2 customers found this review helpful. Pete DeVries Monday, Nov 12 2018 (about 6 years ago) 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… 2 customers found this review helpful.

Wayne Friend Verified Owner Thursday, Dec 9 2021 (about 3 years ago) Tekin RX4 Hardbox Waterproof Sensored/Sensorless D2 Crawler ESC I love the RX4, brilliant for low speed crawling as well as being punchy when coupled with a ROC412 Nolan Hauge Friday, Aug 23 2019 (about 6 years ago) Tekin RX4 Hardbox Waterproof Sensored/Sensorless D2 Crawler ESC Great ESC!
