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
weight is 210 pounds (no chute, no batteries). The empty weight is 626
pounds which seems quite high. The glider POH states that the empty
weight is 560 pounds. Could this be the shipped weight from the
factory minus instruments, radio etc?

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

Thanks

Mike
