05-29-2025 MkI Viper Launch

Flight operations continue with the Viper hybrid rocket glider. For this launch, I used 50 ml of unstabilized HTP at ~ 87% concentration and 2 ml of denatured ethanol for the oxidizer. The fuel was PLA infused with KMnO4. I pressurized the propellant to ~ 140 psig. The MkI Viper cleared the rail guide and reached an altitude of ~ 30 feet while yawing to port.
