RUT/ST - Total Energy Probe - Fuselage - for ST1 mounting adapters
This total energy probe is designed to be mounted vertically on the sailplane fuselage. It is my understanding that fuselage mounted TE probes are not nearly as accurate as TE probes that are mounted near the top of the vertical fin - pointing forward, but sometimes a tail mounted probe is not possible or practical.

Mounting Tip
esa-systems recommends mounting this type of probe with the tip pointing toward the front of the glider. In the images at right the nose of the glider would be to the left.
