I strapped me new keychain camera t' an Estes Antares rocket with streamer recovery powered by an old B6-4 rocket engine (manufacture date: 27th March 1977). Begad! T' second flight be an Estes Patriot rocket with parachute recovery powered by a German made MOOG*NICO B4-4 rocket engine (manufacture date: 1988). These mini cameras are great fun t' play with.
