Hi Guys - The quality of the TE probe you need is related to
the square of your speeds of interest. A floater and/or low
L/D glider is going to be fine with a low-performance
probe. The '26 driver that's bothered by the airvent effect
should simply remove the canopy and all will be well...

Speed and drag, it would seem. The need for TE is going to be driven by
how long your stick thermals last, which will be made longer by higher
speeds and less drag.

The vent doesn't bother me exactly, it's just an interesting effect I
thought about. As far as the sport canopy goes, the last time I flew I
almost froze to death right in the air, so I'm going to have to pass on
that idea at least until the weather turns warm again.
