inability to use differential braking, which increases the radius of turns. 

The rotor blades demand special consideration during ground handling, as turning rotor blades can be a haz- ard to those nearby. Many gyroplanes have a rotor 

brake that may be used to slow the rotor after landing, or to secure the blades while parked. A parked gyro- plane should never be left with unsecured blades, because even a slight change in wind could cause the blades to turn or flap.
