Drill motor torque curve
 

Does anyone know where I can find the drill motor's torque curve? Is it in the manual or one of the updates?

it's in the manual.
 

Yup! The drill motor curce is inside the manual. It should be inside "Kit of Parts: Appendixes B-G" at the back of the manual, where they have specs for everything, after the additional hardware list.

If you go to FIRST's webpage, you can download this 25mb pdf file that will contain the exact same page. You should be able to find that @ http://www.usfirst.org/robotics/doc_updt.htm inside competition documents.
