Spektrum RC Firma Crawler Sensored Brushless Smart ESC & Motor Combo (2100kv)
Fantastic Combo for Crawling. I have this setup in two of my SCX10II rigs and couldn't be happier. The low end control is perfect, you can crawl as slow as the throttle potentiometer in your TX will allow, and still retains plenty of wheel speed for ascents and mud should you need it. The ESC setting are great as well, pretty much what you would expect from a Hobbywing AXE plus Spektrums compatibility.

Spektrum RC Firma Crawler Sensored Brushless Smart ESC & Motor Combo (2100kv)
Love this system! I installed this into my Axial Ryft Crawler build and it is amazing! The throttle control is unbelievable and drag brake is flawless. My Ryft is heavy as well,all Vitavon portals with brass,Vitavon axle in the rear with 4ws and front Treal axle with all brass options so she's thick and this system don't miss a beat. I even took the fan off the Esc immediately,never ran it and it has never gotten hot. If you would like to see it in action on my Ryft check out my YouTube,Hardlines&fullsendRc
