"I loaded the 710k hex file, and it said the firmware was 252950 bytes.  It loaded successfully and appears to be working.  If anyone knows how to tell the size of the firmware based on the .hex file size, I'd still like to know.

Also, if anyone had…"

So, I've been digging into the ArduPilotMega (Beta 1.0) code to get a better understanding of how it works. I figure that it will help out in troubleshooting any problems I might have, but the real reason is that I'd like to modify the code to suit…

What is the frame rate of the ArduPilot Mega?Are there any timing diagrams that show the order and timing of the different tasks during each frame? (I.E. feedback/PWM input measurement, control law calculations, PWM output generation, etc...)Thanks.
