Skystars F7 Pro4 + AM60 AM32

Skystars F7+AM60 is a powerful stack for freestyle and racing drones.The controller with modern F7 processor has 16MB of blackbox memory and 5V/3A and 10V/3A BEC. The unit also has a connector for both DJI FPV and OSD connections, so it can be conveniently used on a drone with both digital and analog video transmission. The pads for connecting the LEDs in the corners of the unit are also nice. The integrated barometer for altitude measurement also comes in handy;

The AM60 ESC uses the 32-bit AlkaMotors AM_32 firmware, which is considered by many to be the best current firmware for ESCs. The base of the ESC is a 6 layer PCB with 3oz thick copper. This allows the ESC to convert even high currents. Large 5x6mm 40V Toshiba Mosfets are used. For better cooling, the ESC is equipped with an aluminum heat sink. Also included is a capacitor that needs to be connected to the battery leads on the ESC.
