Launch of my Estes Ventris on a CTI Pro29 2-grain G88 Smokey Sam to 1179ft. The G88 is barely a G at only 84N total. Burn is fast and definitely smokey. Delay was drilled to 6 seconds, 7 seconds would have been ideal. Overall good flight. The 808 cam had to be mounted at a slight angle which is what imparted the spin going up.
