I'd be interested to know what he's charging for those if you don't mind saying. I was dead set on getting an electric Thundergull at one point, but I just never pursued it. RustyTheir Zero electric system conversion is pretty slick - I just bought one for our little plane.
I got a reply to a question last month, but I do not think they are producing many planes.A couple of questions regarding Earthstar in California. Airplane is Thunder Gull 2000:
1. Is Earthstar still a going concern? So far, no response to e-mail or phone, but my mate has only been trying for a couple of weeks. The web-site feels pretty current.
2. Peter is 1.87m and 95kg and 71. Roughly 6'2" and 200lbs. Any ideas on cockpit size, pilot weight and electric start?
3. Are the Gull 2000's only kits, or can one get a fully built one?
4. Does anyone know if there are any flying in Australia (or, at a pinch, NZ - though international flight restrictions could be a problem for a while yet).
You have it backwards. It easier to get laminar flow at lower Reynolds numbers.Clanon
What's so good about the wing - the airfoil section?
I didn't think laminar flow was achievable on ultralight wings - at 2.3M (63mph, 4.75 ft chord) I would think the Reynolds number is too low to avoid turbulent flow.
