Ace R/C markets the Thermic Sniffler (undoubtedly TM) which is
what you are looking for.  It is used by R/C glider pilots.
It sends out a continuous tone (I believe on 50-some MHz) which
varies in frequency according to the vertical speed.  I believe
that the cost is around $150 with receiver.  The package weighs
a couple of ounces.
