He patented the idea in 1903, and by 1906 was testing gyroscopically-stabilised cameras launched by stick stabilised rockets and recovered by parachute. In 1912 he demonstrated his perfected rocket to the Austria Army. The rocket had a thrust of 400 kgf and was 7.5 m long. It weighed 42 kg and reached 800 m altitude in 8 seconds. Maul also proposed a version of the rocket for sea rescue. The Army tested the rockets in the Turkish-Bulgarian War of 1912-1913, but found that aircraft were much more effective in the reconnaissance role.
