Bought this rocket for our first flight -- pretty cool, but did not launch the rocket 900 feet. Learned each letter grade on a rocket is twice as powerful as the other (example A - 200 feet, then B - 400 feet, C - 800 feet), so make your decisions based on how high you want to fly. Make sure you read the instructions and learn what type engines fit your rocket. Size D and E may not fit a small rocket

This is the perfect mid power engine.If you fly small models it will go very high. Larger models fare well with this engine.Good altitude without risking loss for average fields.Estes engines are very reliable. When used correctly are fun. Not all packages have wadding so you should buy it separately,two variations in packaging.B engines have twice the power of A,an C have twice the power of B. I recommend if the model lists A motors can be used,be cautious,B,engines will loft it high. If it lists B as beginning range ,B-6-4 is perfect. B-4-2,B-4-4,B-6-2 are less common.

Estes is know for their great quality model rockets and model rocket engines. The B6-4 is one of the most common engines. Not all areas have hobby shops or stores that carry rocket engines so if you can't find them in stores I recommend just getting them here on Amazon. It's just easier.

Perfect size for urban lanches at parks. Shot the AMAZON high into the air, but still landed back in the park. Get extra wadding. This one will blow / burn pieces out. Great size motor!

First time flyer - long time watcher. These engines "rock" it. Followed the simple instructions with a 9 year old and he had no trouble getting airborne in a flash. Highly recommend them.
