Accelerometer Sensor ID & Gyro Sensor ID

Are the ID values for the Accelerometer Sensor and the Gyro Sensor, unique to each unit?
i.e. Is yours different than mine?
INS_ACC_ID 1245450
INS_GYR_ID 2162954

they are based on the physical hardware config

Thanks Michael . . . so, if two helicopters from same manufacturer contain identical hardware, these numbers would be the same for both?

yes, more or less…

As a side note . . . who decides which airframes are listed in Load Presaved in the drop down on the extreme right side of the Mission Planner full parameters list?
