Schottel drives
Edward,the assembly as you put is in the shape of a harbour tug called, W.H.Parr, and operates in Port Nelson N.Z. I wanted to build this tug as it is named after my mothers cousin. it was built in Dunedin in the early 70s. I was able to obtain some drawings and have built it from scratch, I have had some help and guidance from club members. it got its bottom wet last Wednesday for a brief period, it sits square on the water but slightly bow down so a little bit of shuffling about with batteries might get me somewhere !! I am a bit reluctant to add weight at the moment but I built it to carry 2, 12v.7amp lead acid batteries.
It's scale is 33 to 1 which makes my model 2' long so it's a bit tight for space inside.
If you look up W.H.PARR on the internet you should see what I am building.
Steve.
