Hi all

I am now the owner of a lovely 1973 Grob built Standard Cirrus - a thing of beauty.

What intrigues me is that the the glider has no water ballast in the wings and looks as if it came straight from the factory like this. No connector in the wing root and nothing in the cockpit to indicate there was ever water ballast functionality.

I always assumed that a run of manufactured gliders such as Std Cirrus would have water ballast in the wings across the whole range, but obviously not.

Has anyone else come across this?

Very curious.

Thanks for any info.

All the best
Ian
