Two strokes belong on chainsaws

I worked on a UAV helicopter project some years ago. One of the big problems with 2 strokes and helicopters, if the use oil mixed in the gas, is lubrication at high rpm/low power. Since the oil is in the fuel, if you reduce the power (like in an auto or descent) you reduce the lubrication. This is a great way to seize the engine. The engines, being simple and durable, may well start back up after they have cooled down a little bit, but that will be little use to you during the event.
