I had "lots" of experience with my MA1 before I got my MA2. I crashed the MA2 because I have a backyard like yours (trees, water, etc) and I did not study the MA2 manual beyond the basics. So my advice is to study the MA2 crash reports (including mine) on this forum, and train yourself to avoid all of their various errors. The low battery RTH snuck up on me, and did not handle trees well. Now I know how to watch the screen for the right data, to avoid surprises, and to take back manual control if circumstances allow. The hay field sounds perfect!
