I have not received my soaring magazine yet this month but I hear there
is an article dealing with fin mounted vs fuselage mounted TE probes.

Anyone have thoughts on this issue?

I read Dick's article with interest. He did his usual incredibly through
experimental work to support the probe design.

I see several advantages to the Johnson probe.

1. It's likely to be less sensitive to yaw with its single hole aft.
2. Shorter tubing runs that can be easily inspected and replaced if needed.
3. It eliminates the danger of breaking the fin mounted probe while
installing/removing the tail dolly.
4. Possibly faster and more accurate vario response since acceleration and
line capacity errors are reduced.
5, One less part to install (or forget)
