Skystars AM60 is a powerful ESC for powerful 5-7" copters. Thanks to the thick layer of copper, gold plating and six-layer PCB, the ESC can carry high currents. The ESC has an aluminum heatsink, which helps to dissipate heat and at the same time contributes to the mechanical resistance of the ESC. The great advantage of the ESC is that it uses the AlkaMotors AM_32 firmware, which is considered by many to be the best ESC firmware.
