# Do propellers at different angles work the same? And do intersecting flows of air work the same?

1. Say a propeller pushing thrust downwards generates 70 lbs of force. If you tilted the angle of the system to 45 degrees would it generate the same thrust?
2. If you had each rotor angled inwards of a system like this, assuming that the system is on the ground, would the airflow be the same or cancel each other out a bit? (the arrows is airflow direction)

Thanks
