ok marc, i understand now. I still ahvent decided on what the best
route is for the data gathering. How much do the 302's typically
run? I glanced over their website and it seemed to me that the bare
logger wasnt too spendy, but then if you wanted to add on a vario
display, etc etc. it could get pretty pricey. what all would I really
need? just the bare logger?

You'll need a Cambridge 302 (not the 302A, which is a flight recorder
that doesn't measure airspeed or temperature). If you have a suitable
PDA and software, you don't need the 303. So, minimally, the new cost
is just under $2800. I've seen used ones in the $2000 range.

If you aren't so worried about the flight recorder, you might be able to
pick up a used Borgelt B50 in the $500 range. These output IAS, TAS,
vario, and outside air temperature to a PDA, plus they are really nice
varios...
