when it was calibrated
3，Upgrading the software（.bin）and it parameter
data（.param）
3，Upgraded the software by Walkera FlyConfig（.bin）and upgraded the
parameter data by MissionPlanner（.param）
4，Recalibrated the radio
4，Recalibrate the radio at Walkera FlyConfig，Pls. notes that each of channels of
the switch in the radio should be tested
5，The radio's setting is correct ?
5，It should be selected by Airplane when it was checked the "type Select"（It
would be a safe and best way to TRANSFER the data from a working radio ）
