84mm
I guess they need to update the website.
I assume your nozzles are 100/90?

I take it the outer diameter is 100mm front and 90mm rear or are these dimensions slightly more than stated,
Just going by the fact your prop is 84mm and not 80mm as it mentions.
Looks to be a solid product.

How do you control a schottle / pod drive on a model? It's one thing ive always been curious about


At work when manoeuvring it's done with these leavers, - haven't seen anything like it for a RC before


Do most not use the schottle / pod in 360? these are our controls for 3 20MW pods

I am steering towards 360 (pun intended)  {-)
I want to keep it simple (without spending a mint) and control is not about speed but accuracy IMHO


I will use two rotary knobs to control and indicate the position of each kort and port starboard throttles split on left right friction sticks


Only testing in the water will determine what I might change.   AND lots of practice.


From a lot of watching it seems LESS is more, see what momentum does before over reacting.


EDIT
I guess the most important thing is the direction of the thrust, no point applying any amount in the wrong direction. {-)


I dare say in time with OPENTX I can have multiple settings and flick a switch for basic sailing controls with no tow OR simply put tank steering OFF

Thatís interesting Ray but I would say from experience that throwing a boat around sideways and spinning in open water is a far cry from the control required on a tow with obstacles everywhere
They make it look easy but Iíd like to see them apply it to more than showing off  %%

  hi andy  i know theres a lot of show boating in the video  but they do use these controls for  model towing competitions   in this photo  this is a training tug     future tug captains  train on these models as part of  there  coarse / training!  the tug is a  true scale tug  'bollard pull and  H.P'  the model is approx 6ft loa  and the ASD  units are 6inch dia  the hadsets are custom made and use the  sticks for control!   the ship model is 47ft loa  :o

After reading Andy's post about these Z-drives I decided to order a couple for my new build, the price and the quality is very good.

Im not sure Andy, but really good quality, after working out cost of materials  to make the drives it was a none starter to be honest, the ones I bought are 90mm Schottels, I was that impressed with them I placed an order for the 120mm Schottels for my new build.

Nice Iím happy for you and for Victor, they work hard at OceanWorks with continual improvements  O0 
I canít help but notice that the leading edge of the new props appear to be very sharply profiled.

I found this link to a company that makes the rotation units and boards for your radios.


IMTH Innovative Modelltechnik Hamburg - Home


These by what it looks like can give us a full 360 degree rotation.

There seems to be an obsession with 360 degrees, has any one tried using it in practice on a model? I find 180 is more than adequate and its already very easy to lose track of what is where and how much power in what direction  %%  I would suggest not to waste money on overcomplicating what works fine and just spend time using it to the point it becomes intuitive. These drives at this size are extremely powerful and I have output limited to 25% but for becoming familiar with it a lower output would be easier.


Please donít take this as directed at you Duane it is just a general observation.
Of course full size vessels have very big heads up displays of what is going on

Perhaps we are deviating from subject here, but I'm with Andy/Taranis regarding 360degr rotation or not. If you really like to replicate the real thing, then go for it, but it ain't that necessary.
I don't have a podded model, but I am captain on a 40m ASD passenger vessel, and spend my days manoeuvring to and from jettys that we go nose on to. Very much like a tugboat pushing a vessel. The only times I turn a pod inwards is when turning on the spot or when steering at slow speed and you need that extra force. All manoeuvres can be done by steering the pod 180degr outward, braking, crabbing, steering. You can get unwanted effects when turning a pod inwards and the prop wash hits the hull or fin.
If I could afford it, I'd definitely buy the German system that replicate the real thing, but you could achieve almost the same thing with a much less complicated solution. If I ever build a podded model I'll try to use my Robbe F14 with two sets of twin sticks and 180degr serves.
All the best!
