3040/10 on 12S is too much RPM for that sized hull. I don't have first hand experience with a hull that size, but in general, the larger they are, the lower the RPM and larger diameter props.

What would be the optimal?
35000rpm?

Again, I have no experience with a hull that big. I can tell you that 3040/10 on 12S is a hot SAW setup for a 135-150cm sized boat, which based on your original post, is not what you're after speed wise. Your motors can be wired in Star or Delta to alter kV giving you some additional flexibility in setup.

As I have seen a few another setups 3060/10 on 12s is optimal. 30000 rpm is not too high.

Sorry, I edited my reply. I incorrectly typed 3060 when I was still referring to the 3040/10 as being too hot. I agree, the 3060/10 is a much better choice.

Start to build the steering and Im a bit confused. I know this is a stupid question but what is it for the hydraulic dummie?
And how to install the wire rope?

[fweasel]

The hydraulic dummie arms are for cosmetic purposes, and is meant to mimic the hyrdraulic steering on the real race boats. There are two installation possibilities. One method, the hydraulic dummies are actually part of the steering linkage system. The steel flex cable is usually soldered or glued into a threaded fitting that attaches to some type of ball joint on the rudder attachment. the flex cable passes through the hydraulic arm, routed through a teflon or brass tube inside the hull, and then is attached to a servo arm on your steering servo.

Some builds use the dummies purely as a cosmetic ornament and route the steel flex cables straight into the hull, attaching to the steering servo arm with no curves or change in geometry. This often results in a more linear steering response and greatly reduces friction. This method is what you have pictured above.

I prefer to use the hydraulic arms as part of the linkage for scale looks. Its usually best to mount them as narrow as possible on the hull transom to maintain proper geometry between the rudder and servo horn pivot points.

Thank you fweasel.
Now its clear.

Little Sunday work. Was made a small parts for steering.
