When good rockets turn bad... |

Every picture tells a story, these are no exception! 2nd scratch-built sugar rocket not as successful as first :p
Using a new KNO3 formula, the rear enclosure of the motor blew out due to over-pressurisation. Very spectacular, but ultimately didn't make for a very good flight at all. The formula was from Jimmy Yawn's fantastic site - Recrystallized Rocketry. This is the Skillet RCandy as described on Jimmy's site:
KNO3 - 64%
Sucrose - 28%
Dextrose 6%
Fructose - 2%
The formula was then catalyzed with 1.5% Red Iron Oxide.
The resulting RCandy had enough thrust to propel the 1" 1ATM sample along the ground during the burn test. Great formula, just need a better motor housing!
