Hi Ray,
Just a note... To make sure the info is accurate, the thrust figures should probably be accompanied by a description of the measurement tool. ex: fish scale, force gauge, hunk of lead lifted off the ground by a cable

, etc.
I have seen and used 'accurate' scales from a local 'all in one' auto supply store that can vary by +/- 4 lb at the 30lb mark.

We use a properly calibrated force gauge when benchmarking an engine prior to shipment.
Later,
Kelly
