Column of black smoke!
By Craig M
November 24, 2016
I posted the photo of the estes ventris. This motor took the ventris to maybe 5 or 600 feet. And the rocket landed about 50 yards away. A good motor rocket combo for a small field. Tomsteve 1987 is right about the hard igniting. I burned the first igniter had to use the other igniter which left me with no igniter for the second motor. I would definitely buy extra igniters. This motor has good sound and great smoke. I will definitely buy more.
