I recommend the fuselage probe. Ten dollars worth of parts and you're
good to go.

See Nicks and Johnson for the original idea and its refinement. This
article is pretty clear about it:

Also, see Sebald for an alternative installation that combines TE
probe and radio antenna:

Thanks, Bob K.


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...
