The company Flygebriken in Sweden decided to test 4 cylinder in their Seagull. In future they want to test the 6 cylinder for LSA. You can read more about this on their website that is available trough this link.
They were very pleased with the installed weight.
They have done the start up recently (Jan 2015). Now we must wait for flight tests and see if the much lower weight will compensate the lower power. The Seagull has standard Rotax 914.
Congratulations for this compact installation.
