Scratch-Built 90mm rocket utilising Australia Post tube and a 'Crayon' nose cone. KNO3, Sorbitol and Yellow Iron Oxide - produced a longer burn motor than with RIO. Good boost, parachute tore free at apogee!
Only cracked a fin on this flight - but I suspect that the Magnetic Apogee Detector may have been damaged. The MAD armed correctly for the 2nd flight and I utilised a faster propellant (and achieved appox. twice the altitude) but the MAD failed to deploy the parachute and it came down like an Indian satellite landing on the moon!! LOL
