Rope tensioning/belaying/feed out.

Um, that servo - and any actually - (I'm new to them)...

It says it can do 1.5 turns.

I would be needing it to do.... well: "infinite" turns.

What is on the reel needs to be fed off and NEVER returned.

A bit of back winding may be needed now and then, but mostly feeding out "rope".
Will that work?
