I agree with captjckirk, it depends on where you're flying. Where I fly, almost anywhere you come down is in corn, or weeds, or leafy trees. In four years of flying, and many crashes, the battery only disconnected one time, and that was when the fuse broke in half right where the battery was mounted. Fortunately, the battery was bright yellow, and I found it on the ground quickly. That explained why the plane locator didn't work, but where was the plane? After an embarrassing long time, it occured to me that since batteries don't glide very far, the plane must be straight up, and there it was, 75 feet above the battery in the trees.
