Why are larger servos so expensive? What can be done about it?

It's probably because the market for them is not as competitive as it is for smaller ones -- that, and the amount of additional materials required to make them, which increases.as the cube of the linear dimension change.

If you do not mind taking it slow, I have used the small Futaba servos sold by Parallax to move up to 20lbs on a level linear track. Just gear it down to a 80:1 ratio.

I use Vigor VS-11s regularly, quarter scale. Great for regular use or CR mod. Hobby King sells for under $10.
