The E-Factor CRS electric propulsion system was designed by my good friend Michael Ramel.
Michael was not only creating new aerobatic classes like „F3A-Indoor“ (today F3P), he was also a revolutionary in technical matters.
In 2006 he introduced the world’s first Contra Rotating System, the E-Factor. Years before he was the very first person to ever fly F3A with an electric power system.
In that time not many persons shaped the scene like Michael Ramel and because of his technical pioneer work he was awarded with the 
Oleg Antonov Diploma by the FAI in 2013.  ( in the beginning of the 20th century Oleg Atonov was a legendary Russian aircraft designer.)
 
I´m proud of all my achievements, which I have flown since 2011 with E-Factor CRS, the ORIGINAL of all contra systems. Furthermore I am happy to have received the exclusive distribution of this power system.
