Estes Model Rocket Engines E9-6

these motors are a lot of fun. they are substantially more powerful than the D size motors. they will shoot your rocket nearly twice as high. they are much louder and produce more smoke than smaller motors.not sure what other reviews are talking about when they say it only flies as high as other E9 motors. the E9 is the impulse power and time, so all E9 motors have the same power...

I shot the Eggscaliber Rocket with a raw egg in the nose cone and the rocket took off great the egg parachute opened right on time and the rocket parachute opened on time it was a good experience.

These are real Estes engines and worked well, also got here quickly.

My model rockets have reached new heights with these engines. Never any misfires. The thrust seems to be as advertised and doesn't moderate between different units.

For the price, power and performance, I got exactly what I paid for and more. Will buy more again soon.

GREAT PRODUCT! FAST SHIPPING! JUST GETTING BACK INTO ROCKETS AND THEY HELPED A LOT! WILL BUY MORE! A.S.A.P. AND MORE STUFF AS WELL!

Work. Too expensive though.

work like a charm
