$50 K450 KNSB sugar rocket launch
$50 K450 KNSB sugar rocket launch
Jul 18, 2022 - 4-inch minimum diameter two grain K-450 KNSB sugar propellant launch.
Rocket airframe was made from a discarded 12-foot-long cardboard tube from a home improvement store, cut into 12 pieces to make the airframe, dual deployment av-bay, and fin can using Elmer's School Glue...no epoxy touched this rocket. A low cost demonstrator rocket to show high power rocketry doesn't have to be expensive, the goal was under $50 for the rocket. The entire project including the rocket, K-450 propellant reload and Eggtimer Apogee flight computer cost $24 minus the parachute and motor case. Those were also made at the cost of $8 for the parachute and $14 for the metal (both made for a previous project). The nose cone was the top of a Shasta soda bottle.

Statistically, we got a better chance of being bitten by a shark." Then I showed her the scar on my elbow from a shark attack. I said, "I got this when my plane went down off of Florida." - Dennis Regan
