I have just done a weight and balance on our Club's Grob Astir CS and
after computing the empty weight and C of G we find that the max pilot

pounds which seems quite high. * The glider POH states that the empty

Does anyone else fly a CS and if so what do your numbers compare at?

Thanks

That seems about right. My Speed Astir II weighs 630 lbs, but the POH
says something like 550. I think Gary Boggs has one also, you might
want to try to contact him directly, and there's also a Grob
Sailplanes Yahoo group you can join (althought there's not much action
there!)
