I enjoy slow dramatic launches of fat rockets. Apogee Components lists E-16W as an option for the 3" Der Red Big Max with an apogee of 787 ft. However, I see different apogees depending on where I look. Thrustcurve lists an apogee of 159 meters (521 feet) for the same E-16W motor.
I plan to build light (12 ounces). The other motors that I would like to try include Estes E12-4 (cheap black powder) and Aerotech's F12-3J Reload Kit 24/40. However, the different velocities off the rod and max altitude from these sources have me confused. (Apogee Components list the model weight at 9.7 ounces- Estes at 14 ounces, and Thurst Curve at 12 ounces). This Estes E-16 flight was 250 feet.
How can I do a better job of planning this slow launch/ cheap motor selection? Note: the launch rail is 8 ft.
