Fun with Fences

Talking about github.com/ArduPilot/ardupilo... which I hope gets merged soon.
The main new feature is support for minimum altitude fences on copter.
I should point out that the avoid behaviour is only in Loiter - switching to any other mode will cause normal fence behaviour to occur

The hard-deck on this hop will be 10 feet

Really looking forward to this getting merged. For the landing "problem", could you not just switch to RTL or LAND using a switch or button?

Absolutely - RTL or LAND will work fine.
