Not all Sod Farms are like that. The Davenport R/C club's field IS a sod farm, and they fly glow models there.
As for killing grass with exhaust, I think only in the extreme cases where the hot exhaust is directed directly into the grass for extended periods, which seldom happens with helis, since most people don't sit on the ground long with their engines above idle. Most of the brown circles I see around our fields are from planks with horizontal-mounted engines that have the exhaust deflector an inch off the ground. Everyone who has been around R/C planes for more than two seconds has seen a planker straddle the tail while he runs the plane at full throttle for a minute or two scorching the hell out of the grass under the exhaust. There are a lot of these little circles that are more than just browned, there are many that are blacken and charred down to the soil.
