When I cheaped out and bought Suppo ESCs, I was faced with the task of flashing them with Simonk. It turns out that the ESCs worked well with the tp_8khz.hex file. After a few hours of aggravating soldering I got four ESCs flashed. This was very helpful http://www.atmel.com/images/atmel-24…_datasheet.pdf
