Tony, get a TE probe! *Dick Johnson had an excellent article in

Or go find an old glider that isn't being flown anymore and borrow
one!

Kirk,

I had a probe on the Cherokee before I recovered it last winter. I
built the probe from the Dick Johnson article. I'm not sure that it
ever really made a difference. When recovering I decided to just go
back to static for simplicity and not having to poke a hole in my new
fabric. Plus some discussion with Dave Nadler here led me to believe
that having total energy in a glider that weighs 600 lbs and cruises
between thermals at 60-65 mph really isn't all that necessary. I can
do my best zoom climb and still not gain a whole lot of altitude. I
wasn't able to detect much of a difference in the response from my
Winter vario with or without the TE probe. So I think that with my
lightweight, low L/D, low wing loading, low speed glider I am not
placing a TE probe install very high on my to do list. Higher
priorities are rewiring with Tefzel and getting an audio vario in the
panel as I'm planning to fly the Region 10 contest this year. Plus
there are these bubbles on the leading edge which probably don't
affect the performance one bit but are annoying me.
