RC boat rudder made simple a€“ learn how to figure out type, size, linkage, placement of the rudder and how to tune your radio controlled boat for best steering response. An RC boat rudder that is scaled down from the original plan of a full-size vessel will almost without exception have an impaired steering response, and never handle as well as the original vessel. This is a home made RC boat rudder for an unfinished Lindberg Trawler plastic kit to RC conversion. The reason is quite simple: The physics behind rudder size doesn't change linearly with scale. However, area is not the only property that effect steering performance and scale appearance. Suppose we have two almost identical vessels a€“ one with a single propeller and rudder, the other a dual set-up. Another thing that is often overlooked, is where ballast is placed along the length of a hull. Some builders seem to believe that by having the rudder angle increased will compensate for a small rudder area. For high performance sailing yachts and power boats, I'd recommend using ball links in all link joints.
Here the same RC boat rudder showing the how the rudder angle has been reduced by shortening the servo arm - it is now 75% of the length of the rudder arm. A minor issue with this RC boat rudder arrangement is that the stroke of the rudder no longer is perfectly centered - it's geometrically impossible.

It comes down to this: a scaled down boat, all else being equal, need a bigger rudder area than the original vessel.
Some of the other propertied include: shape, amount of balance, location, rake and shape of horizontal section. Obviously, your boat will still have issues when navigating at lower speed and when docking etc. Some ships around the turn-of-the-century actually had the propeller behind the rudder a€“ no joke. Most of us place the model in the bathtub and lay weights on or in the hull until it is trimmed to design waterline.
A balanced rudder has approximately 20% or less of its total area in front of the axis-of-rotation.
Ball links are commonly used by the RC airplane and helicopter community and also in RC car and buggy. This is the most convenient, since the arms on the rudder and servo are the same length.It is also the "correct" way to make a servo linkage as the rod will stay parallel with a common center-line through the two pivot points. However, the difference between the left and right stroke is less than one degree, so in all practical aspects it will work just fine.

Examples include warships such as destroyers, battleships, and civilian and merchant ships such as oil tankers, merchant ships, liberty ships, barges etc. Those were mostly torpedo boats some of which were in the British, French, Russian and US navies.To mimic this on a radio controlled boat is sure to disappoint in terms of performance, so avoid the vessel all together or side-step the design with a more traditional layout where the rudder is behind the propeller. However, with dual propellers there is an opportunity to implement an independent motor control scheme for the left and right hand propellers. This is all fine and good but most of us don't realize that weights placed at the extremes will give the hull a higher inertia (in the yaw axis in airplane terms) than one where the ballast is placed centrally. My vote goes to deep and narrow, here is why:Balanced or not, being narrower will place the center of pressure on the rudder closer to its axis than a wide rudder.
They are back lash free and give superior control in critical applications.For modest performing scale boats and casual RC boats in general, a bent up piece of piano wire will do the job just fine.

At the same time, since the main purpose of a radio controlled boat is not being a conversation piece for your living room, the majority of builders would rather have good performance on the water and choose #2.For the rest of this page, I'm assuming performance trumps scale appearance as it otherwise applies to static scale models.


I can't vouch for either of these "rules", but it may provide you with a place to start your own trial & error.If you have a model, whose response you're happy with, use its rudder arrangement as a guide for your new efforts. Letting it grow forward may be less obvious and look better.In the old classic "Elements of Yacht Design" by Norman L. This will take strain off your steering servo.A deeper rudder will also have the center of pressure lower down. There is little sense in reinventing the wheel.The area of your RC boat rudder may be the most important factor effecting the steering performance of your radio controlled boat, but as I've hinted to earlier, there are other factors as well. If it is sufficiently deep down (and below the a€?center of lateral resistancea€?), the effect will be a significantly reduced tendency to heel when the helm is hard over, especially on shallow and narrow hulls.A downside to a cantilevered narrow and deep rudder is more strain on the rudder stock. I use 17-4 PH stainless steel wire.Below are a couple of illustrations showing a typical RC boat rudder linkage. If not lonely because they are faster than galvanising RC boats but also because they are a good deal angstrom peachy make out louder.When iodin began researching how to smother nearby this became interested in atomic number 49 the history of my hobbies How To Build A Rc Boat-5. If over done, a vessel where the ends are too light will look out-of-scale when encountering rougher water and appear more cork-like. When sailing and the boat is heeling, it is common that the rudder needs a substantial trim to one side just to sail straight (called "weather helm"). This, in my opinion, is a minor issue and not something I've ever really considered given the vast benefits.The cross section (As cut parallel to the design water line) has varied through history.
It is best to make sure the servo arm and rudder arm are parallel at neutral position.Also note the "V" bend - its a great feature allowing you to bend the linkage outside the assembly and tweak the length by adjusting the angles of the "V" once its all mounted in the model.
His reasoning is that, having a balanced rudder means the front piece of the same is disturbing the fairing of the hull-rudder transition on the opposite side of the hull. The most advantageous shape is to make the rudder as thin as possible in general, but in particularly at the trailing edge.If the rudder is free standing (not integrated in a keel or skeg), the most efficient shape is that of an aerofoil.
If the rudder is integrated into a keel such as were the case in sailing yachts from the first half of the twentieth century, the rudder is best faired into the keel with the rudder stock being a round rod at the leading edge.Sometimes you see raking rudders on sailing yachts and some historic ships. If that is where your interest lies, there are other really good resources for information on the web.
