Measuring Airspeed

[green66]

Hi all,

I'm looking for an airspeed measuring device that will transmit airspeed data to a receiving unit to show current airspeed (preferred), or something that can log airspeed over time for download to a laptop after landing. A turnkey system integrating a sensor and all electronics would be nice, otherwise a kit or plans/schematics.

I'd like to put such a system into a glider, probably just temporarily, as an aid to trim for a certain flying speed (lift coefficient), or to stay above Reynolds numbers where the polars start breaking down.

Any info, links, or words of wisdom appreciated.

Here is a link to a project that does what you want: Click Me. (http://www.electronic-engineering.ch/microchip/projects/alti/alti.html)

The 10mW output will require that you have a ham license.
