with the 18th scale stay away from Mamba motors IMO they suck..go with a Neu 1105/2y on 3s or a Hyperion Yc-22 long can both motors have extra torque that the Mamba dont so you can gear up for extra speed...but I really do like the ESCs especially the Micro pro
my future plan is to try the 1105/2y on 4s....I will be sure to have plenty of diffs on hand...LOL
