Skystars KM55A Mini AM32

Skystars KM55A is a powerful ESC for racing and freestyle copters. The KM55A uses large 5x6mm mosfets, which make the ESC suitable even for more powerful 5" copters. The aluminum heatsink helps improve heat dissipation and protects the ESC from mechanical damage. The big advantage of the ESC is that it uses AlkaMotors AM_32 firmware, which is considered by many to be the best current firmware for ESC.
