There is Two Series of NQD Boats..

Earlier Models got the 540 Sub Drive while the Series 2 Gets the Two Type 380's surface Drives

Some Hydro's got working rudders others didnt ...

I mean it seems like there is 2 Versions of All Boats.. You just never know which one you will get..

I mean I was bidding on a Series 1 and ended up with a series 2..
