Yes, it can be achieve both mechanical and electronic.

Some of the more expensive Transmitters have a feature called EPA (end point Adjustment.

Or you can buy the excellent ACTion - P96 SERVOMORPH  - http://www.action-electronics.co.uk/mixers.php

You can also extend the range (at the cost of fidelity and power) by using longer servo arms:

I have done it using gears to make a cheap purpose built "sail winch".

But I wouldn't recommend it - very fiddly!

It's easy enough to make a longer arm. I made one out of aluminium and screwed it to the original.

I looked for one to buy (like the one in the video) but couldn't find one long enough for my purpose.

Or as Martin says, you can use Dave Milbourn's P96 unit, which works.
