3 - Brief History

The ELECTRAVIA - E-PROPS company is also known for its electric motorizations systems developed for leisure aviation : engines, controllers, dedicated instruments, batteries BMS and dedicated propellers, as well as for aircraft equipped with these new successful and silent propulsion systems made between 2008 and 2014.
During 6 years, 70 aircraft with electric engines have been developed by the team, including the famous "ELECTRA" (1rst worldwide 100% electric aircraft, 1rst flight in December 2007), the CRI-CRI Cristaline (1rst worldwide electric twin-engines, world speed record for electric aircraft from 2010 to 2018), the E-FENIX (1rst worldwide electric two-seater paratrike), the E-SPIDER (1rst worldwide electric two-seater paramotor), the ELECTRO-LIGHT (electric motoglider range 1h30)...
At the same time, the E-PROPS propellers, first made of wood and then quickly made of carbon, met with increasing success.
The team is now exclusively dedicated to the design and manufacture of its E-PROPS high-tech carbon propellers.
Since 2018, E-PROPS offers 4,400 models of ultra-light propellers for paramotors and has become the world leader in this type of propeller. In 2020, a range of more than 100,000 references of hi-tech carbon propellers for Aircraft / Ultralights was released.
In 2022, E-Props has started the process with EASA, DGAC and OSAC to certify the production (Production Organisations Approval Part 21G) and some propeller models according to the EASA CS-22 standard. First propeller certified by EASA : DURANDAL-3 (March 2023).
