[FW] Tracked 4WD Lifter: Aegis

[R9000]

Hmm. It seems everything I try needs some kind of custom solution. I'd try it, I just have no access to CNC or proper metalworking equipment to make custom gearing. How about something like this or this (both ebay links)? 500N 20mm/s seems decent, when you factor in the fact that the end of the arm will be moving faster tangentially. This, obviously, is assuming everything in the description is true. :P
