I might have a winner. I don't actually have this combo yet but I am seriously considering it. Hangar 9 frenzy 100 with an os 1.60 2 stroke. Every thread has said this plane is severly tail heavy to the point of having to add like 16oz to the nose so this engine should be just the ticket. For those of you not familiar with this plane the auw is supposed to be between 6 and 9lbs with 9lbs being with an electric setup. Hangar nine calls for a 61-100 2 stroke.
