That's why POTW has a guy named Bait.
You can fly jabo low between those trees following the roads and the tanks can't see you until you turn the corner. I stalked a wirbel like that once in an IL2 in the TT object. As soon as he open fire I dropped down between the trees, followed the road around he was sitting on. Then surprised him by making a left turn off a side road behind him at grass level and smoked him point blank. He had no clue until my rounds hit where I was.
