I have hopefully done my due diligence and examined every Front and Back Image for the Atmel based ESC's that Simon's firmware currently supports. Google Spreadsheet
When I initially bought these a long time ago, they were from eBay and advertised as
35A Brushless Motor ESC Speed Controller RC Trex 450 V2
they appear different from most commonly referenced ESC's as they are 2 PCB's on top of each other. I have tried Googling the details on the Atmel MCU (ATMEGA8L -8AI 0304) but that didn't yield any further information on the Brand or further details of this ESC.
The images I have of them are as follows:
Has any kind soul seen these before and could possibly guide me to the correct firmware to apply to these ESC's?
