Is this servo compatible with standard Futaba receivers?

Yes, it works with Futaba receivers that support S.Bus2. For basic use it will operate as a regular digital servo with compatible receiver channels.

How quiet is the brushless motor in practice?

Brushless motors are generally quieter and smoother than brushed motors, so you should notice less noise and cleaner motion under load.

Can I replace the wire myself if damaged?

The BLS173SVi supports a changeable lead, and a competent modeller can replace or reroute the wire to suit the airframe; follow proper soldering and insulation practices.
