First blush:
Engine RPM
Oil temp
Oil pressure
Stick and rudder positions*
Mixture control position
Carb temp
Throttle position
Airspeeds - IAS and ground (the latter handled by GPS)
The flight profile could be handled by GPS, I reckon.
I don't know if voice recording is really required; maybe that's because I think it would be very boring to hear me chuckling on beautiful days and growling at a less than perfect touch and go.
Another question is data polling frequency. Maybe every second to save memory space?
* This could be done pretty cheaply and with little weight. It's a three Hall Sensors, and the polling and recording software is used in every decent gaming HOTAS and rudder pedal set.
