Review: RC4WD Earth Digger 4200XL - RC Driver
Nov 03, 2014 · A 125 amp ESC drives a high-torque 350Kv brushless motor, which in turn runs the all steel hydraulic pump at just under 300 PSI. $9.99. It's hard to tell when the battery is dumping, so it would be wise to add an alarm to help prevent the battery voltage from getting dangerously low. • Brushless Track Upgrade Kit – VVV-S0040, $349.99
