Motor specs

As a novice team, we're trying to learn about the motors used in this contest. Also, we need to run a few more calculations.

First off, could you please verify that the motor specs in the CDI App Notes are correct? What I'm hearing via the grapevine from other people WRT "which is the better motor for <this> or <that> purpose" does NOT appear to agree with the specs I see there. Also, some of the specs don't agree with the white paper's "Motorpower.PDF" file. For example, the latter says Globe motors are 50-63W (not 23W), and Keyangs are 40W (not 31W), which reverses which may be considered the stronger motor at their respective optimum power points. I'm *SO* confused!

Also, can you please simply ID the motors by original vendor part number, and point me to the three websites that contain the FULL performance curves for each of the three motors? The curves in the "FIRST Motors Etc" Power Point file are tiny and illegible, and I need to see the full curves for each motor for some calculations.

Thanks!
