It's a good low power engine for small rocket kits. I prefer using this engine for my 220 Swift and Mosquito. Anything more powerful and these rockets go out of sight and get lost. Great for small fields and less expensive than bigger engine types. This engine is 13mm in diameter and 45mm in length. The pop can in the picture is for size reference.
