Good
This motor works great never had any problems with it. Make sure you have a strong parachute because it starts coming down pretty fast due to the long delay time. Use this motor if you have a very windy day and you want a longer delay time.
You should try this one.
I have found that this motor works absolutely awesome with my Estes Big Daddy. The sound and the launch are a crowd pleaser. I would recommend you try it with your D size rockets.
Great engine
Used it to shoot an egg over a thousand feet in the air. Very powerful. I use it to shoot my bigger rockets.
good estes motor
