In the air the propellor does not so much throw air as it screws the plane through the air. So while Himat's thoughts make sense while on the ground the elevator won't care about being in the prop wake or not once up to a reasonable speed. Only during ground handling and for the first part of the takeoff does the prop blast become a big factor. Once in the air the stabilizer won't see a prop blast other than somewhat at near the stalling point if you jam on full throttle all of a sudden.
