Deans Marine 'Yarra' motor and rudder setup test

Testing the twin brushless setup in tugboat 'Yarra', with becker rudders.

[@raymondvollebregt-videogra212]

what size motors are those, and the KV rating. together with the prop size ?

[@websitesthatneedanem]

Nice setup!.... can you water ski behind that! ;-)

[@davegeorge7094]

don't forget to dry boat before you leave the lake. Zebra mussels etc.. big fine if u don't. Lock u up.

Hi there could you advise what all the rudder parts are and where I can also get them. I plan to make a bait boat using fleet scale 1/96 river class fibreglass hull. First boat build and I am impressed with your setup. Thanks

[@lverkuijl]

Yes I can, the rudders are made out off aftermarket universal RC boat rudders in aprox. the same saze as the Deans Marine set. They have been cut to make the flap. Hinges and controll pin are made with brass rod and tubing. You can't buy them as these are in this size as far as I know.

@@lverkuijl thank you very much. My next question is this. I have had a look at the motors you used however they are now discontinued as your build is now 7 years ago. Could you recommend motors for me that spin up like the ones you have in the video. Also the shrouds for the props would you mind letting me know what they are aswell. Thanks

@@Poonslaya Any motor 500 to 700 KV will do. The smooth running is not in the motor but in the ESC. Use car ESC's with forward-reverse, with no break function, of where you can switch to direct forward-reverse. XC-10A ESC's have proven to be good in conjuction with the programmer card. Set to direct forward-reverse, and low start power. Search AliExpress on "XC-10a".

Thank you for your input. I am only concerned about the motors not being powerful enough they need to be able to go in the sea and seal with some surf I have seen 1900kv out runners I may go for them and then do as you say regarding the esc

[@derpreue3947]

Hallo, can you advise on some specifics: motor size, KV , Prop diameter. Shaft length and sleeve diameter.Usual stuff...

[@lverkuijl]

Hi, Motors are PROPDRIVE 2830 750KV from Hobbyking, ESC are HobbyKing Brushless Car ESC 10A w/ Reverse, propellers 40mm Raboesch. Shaftlength I dont know without mesuring, but they are also Raboesch, and you can shorten them. Couplings are 4 x 4 mm double joint from Graupner.

What these metal bumps on the rudder and nozzle are for ? Thank you .

[@lverkuijl]

Those are sacrificial anodes. Well, not realy zink, but made of plastic ;-)

[@sergendel]

Lex Verkuijl Thank you) can you tell me the purpose of it? Does it help to keep the flow laminar?

[@lverkuijl]

On real boats these anodes help to reduce the corrosion of certain parts. The zink is a weaker metal then steel or aluminium. It corodes first, so the steel parts stay untouched. Hence 'sacrificial anodes', you sacrifice them to protect the hul an parts. If they are worn out you simply replace them with new ones, the are screwed on to the parts.

man , you are great ! thank you ! )
