All this off the top of my head as I sit at work waiting for a test to
finish....

I've heard the 302 will spew a raw data stream from all sensors to the
serial port after one issues a magic command. The IGC file does not
include any of this info though.

I think the SN-10 is capable of adding airspeed info to the IGC file,
but it is not IGC certified FR.

Borgelt B50 can mix airspeed info into a FR's data stream for
consumption by PDA software.

It's possible that a manufacturer might provide you with a firmware
"upgrade" that you could use for data capture for your project, then
you could reinstall the official firmware for badge flying.
