So pretty simple... I need at least 1500oz in of torque for around $100 if possible.

Thank you,

Plenty of torque to spare (~32,000 oz in.) for ~$80.

Great!!! I think i might be able to make that work. I am making a robotic arm that has to lift about a 1kg from about 20 inches away and this will definitely do the job! A few questions. Can I run this off of a 7.2v 2200mah lipo battery? I want to make the arm all self contained and those are small enough. Also is it possible to make this a "big" servo?

Thank you,
Easton

No, per the owner's manual at the same page, the minimum battery requirement is 12VDC and 12Ah

It is possible, but would require more parts and creativity.
