Updated to new layout with pin harness on the heatsink side. LED is also now included like as in the F55A Pro II.

This ESC is T-Motor's 4-in-1 version of their popular F45A ESC. This 4-in-1 ESC packs 45A into an industrialized PCB layout made with premium features such as a 32bit main control chip, BLHeli_32 firmware, and 6s support. 

The F45A 4-in-1 comes with a heatsink attached to keep heat away from sensitive electronics.

Another small bonus is the 4 x motor wire PCBs that come with this ESC. These go on your quad arms and help prevent damage to your motor wires from prop strikes or other damage. A neat little touch to include them. 

Features

• 32bit Main Control Chip: Compared with traditional MCU of 8 bit, 32bit stm32f051 main control chip enjoys the advantage of fast computing speed and multiple functions.
• Fast Response Speed: Prompt and accurate response on throttle signal receiving for the euphoria from zero lag operation.
• Original BLHeli_32 Firmware: Original BLHeli_32 firmware with powerful performance and diverse functions capable of ESC parameter setting and firmware upgrading makes the ESC far more reliable and efficient.
