Initial GPS lock error

Hi all,

I thought a CH7 "reset home" switch may work here, but I'm having a hard time finding the parameter / place to set that up in Mission Planner.  Is that still available?

I know you can do it with wireless radio via MP, but I don't have wireless

As I look through events.pde, it looks like i

My born-again maiden

Nice work on the code guys.
