This - http://www.ebay.co.uk/itm/NEW-EMS-Linear-Servo-Conversion-Kit-S148-EMO0102-NIB-/291341853059 - might give the right travel using a standard servo, but might still be a bit sudden unless the servo was fed via something like a servo morph to slow its reaction down.  A standard servo with a servo speed modifier might well do the job.
If more torque is needed, and space available, a 2 turn winch as sold by component-shop (up to about 7" of travel on the line).
Essentially, its the same job as the flyboys use for retracting gear.
