Marko: "The remaiden of my FMS Corsair - now equipped with your sound system. On the ground I noticed a little lack of bass-frequency, but once in the air it was - WOW! Very low flown high speed-passes are amazing and giving full throttle after a long steeply dive is turning heads ;-) I love it and can't wait for tomorrow to fly that thing again!"
