07/03/2024 MkI Viper Launch

This month marked the second launch of the MkI Viper. The liftoff mass was ~ 1.45 kg with a propellant mass of ~ 93 gm. Ignition occurred in less than 0.1 seconds and liftoff occurred in ~ 0.3 seconds. I had active control using a transmitter and receiver. The Viper flipped a few times as it cleared the rail guide. I regained control momentarily. However, burn through at the nozzle inlet caused the Viper to spin out of control and crash into the ground. It was an exciting six seconds.
