That sounds like good news indeed, for the UK flying community at least. Still, excuse me for having some reserve: the Skyranger is not manufactured by Flylight, they are merely the importers. So says en.wikipedia.org, at least:

Still, if Messrs. Flylight will go to the cost and trouble of re-certifying the craft for 600 kg (or a bit less, perhaps) it will make an excellent offer. I have one of these for a hangar neighbour, and see it as generally solid and reliable; the pilot-owner has only good things to report about it.
