    +1 on Richard's post.

    As a test for my home built 3DR chassis and DX6i, I hovered about 3 feet off the ground, over thick grass, and shut off the transmitter.

    Instant minimum throtte. Instant descent to the ground. That was the Spektrum Rx failsafe taking over.

    I have yet to explore the APM failsafe options and configurations. Failsafe and Simple modes are two I plan to explore next.

    21 battery cycles on my current airframe (Stabilzed mode only) indicates it is stable enough to venture into other features.

    Experiment on!

    That depends on what you have setup. The Spektrum has a built in fail safe option, which is pretty useless. It gives you a min throttle default, but in a quad copters its useless, because a min throttle your copter still crashes. The APM also has a fail safe option, which you can set to either continue auto flight or RTL. Check the wiki for the setup instructions.
