Put a Evolution 1.0 in mine, got over a hundred flights on it with no problems.
what size stinger? I've got a 25cc gas on my 120 stinger, and that is certainly not overpowered, i can't imagine going with any less power. also, the 120 needs LOTS of weight up front, you will be adding lead to an already underpowered plane.
