Copter4.03,parameter list problem

With copter4.03,i cannot find some parameter,like:
Afs_Parameter,
Afs_Enable,
Afs_RC,enable,
Afs_RC_fail_time,

Who can save this trouble.
Thanks.

I think Advanced Failsafe is a feature of plane, not copter… But maybe someone who is sure can confirm that…

Make sure there are “Afs_parameter”,copter.

Believe me, it’s very useful.

It’s not compiled with default Arducopter. With Plane it is.
