I have one of these in my SCX 10 G-6. I gear mine 87-20. The ROC 412 provides smooth power delivery, for those technical challenges. The ROC also provides wheel speed to move down the trail quickly.

I was blown away by the performance of this motor! Great torque, wheel speed and buttery smooth low speed resolution. I've put about 5 hours of run time on my roc motor and it has been perfect.

Tekin ROC 412 4-Pole Sensored Brushless Rock Crawler Motor (3100kV)
Recently upgraded my Axial RR10 Bomber Kit version with this motor coupled with the RS GEN 2 ESC, more than satisfied! I'm running this system on 3-cell Lipo power with no problems. The startup and low speed operation is silky smooth just as advertised. Running in high gear (with 2 speed transmission mod.) it's every bit as fast as I'd ever want to drive this rig. This is my 4th Tekin motor system and all have been reliable for years, oldest system I've been racing in my 4x4 SCT since 2012, still runs great!
