ok here ar the exact on-air weights (in gramms):
ninja2 with 2 standard battery packs: 514
DNC-N housing with cables to bulkhead: 963
1 SSD: 137
to be added the following:
ball screw on DNC-N: 198
housing ball srew: 42
bulkhead and internal HDMI cables (within camera housing): 100 (approximate, not measured)
total additional: 528
grand total approx. 2.2 kg
If Nauticam speaks of around 1.0 Kg then it is only the ninja housing, I guess.
To counterbalance the additional weight (and some of the negative buoyancy I had before already on my setup) i have added 2 of the new Nauticams' carbon arm floats. Each of them give me around 250 g of a lift underwater.
After this it is pretty even in buoyancy.
