I think you could still get a Sparrowhawk made, but the price went up a lot! The situation is there was not enough demand to keep the "factory" open. It's a shame, I toured it in 2014, and was very impressed. The molds are incredible to see up close. There was even a Perlan Project fuselage off to the side.
If you own a Sparrowhawk (like me) and are looking for information or tips/tricks etc, there is a Facebook page available. If you search "Sparrowhawk Owners" while logged into Facebook it will come up. It looks like a small group that could use some new activity .
I've owned my glider for about a year and its been amazing. The Sparrowhawk flies so well! However, the instant and huge response to lift is the best thing. This is exactly what I expected from a carbon fiber airplane that weights under 200 lbs.
