Hi, RoboSerg.

A sailplane, not a hotliner, will generally use a motor with a kv from 850-1200. One wants to be able to swing a large prop to generate thrust at low speed.

A non folding prop will generate so much drag, particularly if it windmills, that soaring will be virtually impossible.

Soaring time depends on how much current one uses with the motor. A sailplane with four micro servos will be able to run the radio for well over an hour if one doesn't spend time flying under power.
