This is the Mamba Monster 2 25V Electronic Speed Control from Castle Creations.
This is the Castle Creations Mamba Monster 2 1/8th Scale Brushless ESC. The Mamba Monster 2 is as mean as his 
older brother, but isn't afraid of a little water! That’s right; users can run their vehicles down a muddy road, through the 
morning dew, across some slushy snow or just about any other condition you may bash an 1/8th scale buggy or 
monster truck. Plus, the Mamba Monster 2 delivers all of this while retaining an astonishingly affordable price! This 
makes the Mamba Monster 2 the ultimate 1/8th scale ESC when you want power and 
versatility at an unbelievable price. 
Mamba Monster 2 is intended for on-road, 1/8 buggies & truggies, and monster trucks running up to 6S LiPo and
 tipping the scales at up to 15lbs. The innovative case allows for fan changes if necessary. Solder posts now permit 
users to change battery wire length and direction as needed. As always, the Mamba Monster 2 offers industry-leading 
software functions and USB programming capability via Castle Link USB adapter. Remember, the fan is not water 
proof, so users need to remove the fan before they head out into wet conditions.
