Schottel's fitted and secured, also made the fitment for the spur gear this is secured to the body of the Schottel with a 3mm grub screw.

Amazing build with such thoughtful engineering  :-))   I reckon you could pull a full size rowing boat around the lake with those drives!

Cheers Mark, It will be quite some time before she is ready to pull anything  :-))


I have been busy today making and fitting the servo's spur gears and I have done a test run and all is well.

Very tidy with the adapter flange bolted to the larger gear  :-)) ....[the only reliable way to secure nylon to nylon]


Not sure if I missed the text on the directional control for each of the Schottel drives as opposed to independent control for speed [RPM] for each of the propellers  


1. Will each Schottel operate in a fixed parallel angle of helm?, or will they be able to operate at different angles of helm?
2. I understand the latter as a traditional twin motors drive with a speed mixer relative to rudder command etc, however this must be a completely different  %)

Very sexy, this schottel-unit, Brian  :-)) :-)) :-))
however this must be a completely different  %)


Derek
My experience with schottels:
it is completely different. After several tests (with catastrophic results) with my floating-crane to handle the three schottels fully manual, i've bought the solution from imth. with this product
the handling is more usual for me and with the optional and remote-selectable master-slave-mode i'm able to use both ways of handling. synchron or separate.

Derek I normally have both Schottel's working together basically to make it easier to control the tug, I have operated them independently in the past but not with a lot of success.

Ralf the product from imth looks very promising probably worth looking into :-))

Hi Brian I think it's a must to have the twin Aquamaster controls it's just a shame the time and quality of those units not to be able to use them to there full capability I sill remember how to use them if you need some driving lessons (lol) keep up the good work really enjoying watching the build progress >>:-( :police:  take care and all the best Tom.

Great day today got my ESCs sorted  after following the advice from forum members, the motors are running great to be perfectly honest I was nearly about to go back to brushed motors.


Back to the Artic build, today I made the batterie box and fitted the support beams for the deck, she has quite a big superstructure so this gives me plenty of room.

Morning Brian,

May I ask how you have mounted the battery box to the bottom of the hull?

Hello ! just curious what the diameter of the Schottel's are on your boat? debating using two from Ocean works for a similar Orion Moldings build.

Hi Ant I made a wood frame to fit the contour of the hull then laminated this in place then covered with 4mm ply, then made the frame work around the edge. If you look at the photos the batterie box also supports the frame work for the deck this makes a very solid structure, I have used this idea in quite a few of the models over the years and it has not let me down.


Hope this helps
Brian

A bit more done on the deck supports today, on the aft section of the Stevns deck will be a removable hatch to allow any work needed on the drives this is the reason she is named the Stevns Arctic and not the Stevns Ocean. The Stevns Arctic and the Stevns Ocean are identical vessels apart from the stern deck, the Arctic has a large area covered with wood to protect the deck, the Ocean is all steel plate.

Thanks Brian for the info above and it's a fantastic build. I might have to do something similar to my tug. Although hull is nearly 3mm thick fiberglass it's surprisingly flexible from stem to stern.

I'm waiting for delivery of a pair of these schottles in this size. Mine is the same hull as Brian's. 
I think they must be made to order as they have been a long time coming. I know they are now about to be delivered so I'll let you know what I think of them when they arrive.

Looking forwards to pictures

The main delay was another eight days after we last spoke before they hit the courier.
 
The actual journey from HK has not been too bad. The tracking has been very informative.

Yes Brian, I realise that :embarrassed: :-))  I just meant the same size.
 
Mine is also going to be based on Stevns Battler as that has a lower superstructure than the Ocean/Artic type.  At Balne Moor tall superstructures just get blown off course too much

Yes, mine is one of Orion's but I've had it on the slip for about a year as other projects have taken too long!

Andy I think this is the type of schottle that Butts has ordered
