Graham Herbert thinks nature may have figured out a good shape for his IOM foils already. | |

So, there are some definite starting points mentioned above. I have found that there are many roads to take and each builder has their own little twist to add. I am not sure there is a perfect solution, but half the fun is in trying to find one anyway. Someone is screaming at their screen right now. OMG how can you put forth info on designing a rudder for a boat without doing the dozen calculations required for proper this that and the other effect of blah blah blah., etc. Look man, I am not here to present a dissertation. I am here to show you how I built a pretty decent IOM rudder that is probably gonna work out fine. See the previous post for my thoughts how things are going to be OK even if you dont do the math. This is just a prototype whose sole purpose is to verify that I can make a thing that looks about like an IOM rudder to start with. Think about this thread as a vocational tech. class mixed with arts and crafts, not a science class. It is the way I know how to work. Yeah, I took Honors Physics in High School, but even in an Honors class somebody had to get the lowest grade in class and barely pass. Not ashamed to say that in 1991 that person was me! This keel fin is by Gabriel Le Duc. He is doing some nice work in Southern France and I have been following his progress on FB. | |

I just want anyone that hasn’t been there before to go check it all out. The doc you want is in “Other” and called Center of Effort Location - fin or rudder. I will also have the PDF for direct download at the bottom of this post. I won’t re-type the instructions, as they are fairly clear on the process. Here is a detail you should pay attention to. Notice the line chosen as the bottom width of the rudder is not at the bottom of the rudder. The rudder tip has a radius to it and Sailsetc. has picked a location about midway through that curve. If you also notice that if you cut the tip off that line, you could about fit that tip piece in the gap near the leading edge that line. This eye-balled line is a bit of a guess. Likewise the location of of the rudder stock axis is said to be placed “no less than 3mm ahead of the center of effort point”. OK, but is there not a “no than Xmm ahead” limit. So, I chose a spot that was 4.5mm ahead of the CE because that as also the location of the thickest point of the rudder airfoil to give maximum room for the rudder stock. When typing up this post I did not want to get complex, but wanted to do more than just throw out the term Center of Effort and devote a post to finding it with no other info at all on why it matters. Luckily, I found some info presented at at a simple level without using any math titled The Physics of Sailing. Take a look here. Mr. Pierce says that CE and CLR represent the centroid of the average forces that are contributed by the foil. So Sailsetc. has provided a way to find that by estimating the location of the centroid (Center of Effort) of the area of the rudder or fin from a 2D view. I used their instructions to find that location with my CAD software. But I also have the ability to push a button and have the software find that exact centroid point using the 3D shape and did so after doing it “manually” and compared locations. Well dangit, they aren’t in the same place. Rhino3D says the 3D volume centroid is about 10.9mm behind and 7mm above the Sailsetc. 2D area centroid position. Hmmm. I proceed to the next step in the instructions which tell you to draw a line from that point to the leading edge and bisect it. I do so and have a minor jaw drop when I see where the midpoint of this line is. If you recall the CE point calculated by the Sailsetc. 2D method places the rudder axis “no less than 3mm” forward from the CE. My computer has taken the complete 3D data of the rudder and found that axis line at this EXACT 3mm offset location. It is kinda cool that you can bypass some advanced math by essentially just saying “move this point ahead about 3mm in the 2D view to make up for the contributions of the 3D volume and you will probably be alright”. | |

Finally, a picture! Here is a mold half, fresh off the printer. | |
. | |
This looks like an unfinished sanding job, but this is the point you can stop at. | |
. | |
You can also order from Smooth-on, which is where the Amazon stuff ships from anyway, so check to see if you can save buying direct. Make sure your molds are free of any dust, grit, and crud. I mixed up a 15cc batch of epoxy for each mold and did them one at a time so I could keep the epoxy flowing and runny. I only coated the tops of the molds. No reason to do the sides and back. I used a 1/2 shop brush to apply it all over the top. It helps to focus on getting it a bit rubbed in to the plastic. The epoxy may try to pull away from the plastic in a few spots, but working it in just a bit will get it to behave. Make sure there are no puddles, thin spots, or brush hairs (or your hairs) on the surface. Then take several passes down the long axis with your brush, smoothing and evening the coat out while working in full length strokes from tip to the open end of the mold so that excess epoxy is removed as I go. What works nicely at this point is to apply some gentle hot air while holding the mold vertically. This will help surface air bubbles to expand, pop, and self level. It will decrease the viscosity and helps excess epoxy slide down and off the mold. It can also help you smooth out runs and sagging. I have a small heat gun that works great for stuff like this and is fantastic for heat shrink as well. I use it for all kinds of stuff. CAUTION: Do not overdo the heating. You can burn the epoxy or soften the mold. You can cause curing to begin immediately. You can cause tiny bubbles become huge, hardened lumps. What you can get away with will depend on your heat source. Test out your technique on a sample print before you coat the molds. I have quickly flashed a propane torch over epoxy for a second or two just to pop bubbles. I have also spent a minute of time working on flattening a run with a low temp heat/air source. Experiment until you have some experience. Now stand your mold vertically and leaned back a bit so no epoxy accumulates at the open base. It is fine for it to run off the end and drip freely. You can pop the runs off the mold base with a chisel later. Dont be too disturbed with how it looks. My pictures below will show you several mistakes, such as a trapped hair in the black mold. Also, hardened bubbles because it was hot as Hades in my shop that day and the epoxy was bit too stiff by the time I remembered I needed the hot air gun. I even had epoxy build up the open end because I forgot to tip the molds back once I had my area cleaned up for the day. The first coat of this stuff almost always looks like poo, even on my best days. It will come out fine in the end. Looks ugly? Yep. No worries. It will get taken care of. First coat is on. Not pretty, but it is even. | |

This is the black mold from the previous post after being having the first coat sanded, but before the 2nd epoxy coat. I told you it was going to come together! Donât sweat those scratches. Coat #2 will manage them. | |

Make a rc sailboat.
After two weeks at the Wooden Boat school I had finished the ruff-in of the hull, mast, electronics and sub deck ready to start the final assembly.
Here you see the 1/16 inch plywood sub-deck has been removed. I have added ribs to help support the shape of the sides.
Here you see, that all the ribs are in place, I have added epoxy to unify and strengthen the hull.
Fair the hull but don't spend a lot of time on it right now.
Establish the center lines this is when I shape the keel and ballast.
Take pictures and use the black & white mode to help see any fluctuations in the keel.
Try different exposures
A PVC pipe building support makes a big difference for accurate work. It's important to have complete & easy access to the hull at this point.
I use epoxy to seal the underside of the deck, two coats, while it's tacky I apply thickened epoxy to the deck beams and sheer.
Lay the decking from the outside toward the king plank.
To get a deck to look right do not only look at where the points meet but also the trailing edge of the plank. You may need to trim each side of a deck plank to keep both sides of the deck even.
Don't rush!
The design of the deck is completely up to you;-)

Return to RC Sailboats
RC Sailboat Controls are rather different then your typical Radio Control.
We will first look at what channels on the radio control transmitter, control which part of the RC Sailboat and then we will look at the specific setup concerning the radio gear on an RC Sailboat.
The most common type of transmitter for RC Sailboats are the stick type transmitters . The stick type transmitter allows the ease of use over the sail control. On a stick type transmitter referring to the image below, the left
RC Sailboat Controls
side channel, typically throttle on an airplane controls the Sails. Moving the left side stick up or down would draw the sail in or let the sail out. Motion on the stick is vertically.
The stick on the right hand side controls the rudder on the RC Sailboat. The rudder channel operates as like any other rudder channel. Motion on the stick is horizontally.
These two channels are the required minimum for RC Sailboat Controls. You can see all the extra switches and controls on the radio to the right. These may be used for controlling those fancy features on your RC Sailboat. In some cases these extra features include alternate lighting, winches, or anything else to make the sailboat appear and operate more scale like.
RC Radio Receiver
Now that we have talked about the transmitter we will look at the rest of the components that are required in order to run an RC Sailboat. The component that is responsible for talking to the transmitter is the receiver. The receiver is what talks to the transmitter and then converts the radio signal to an electrical signal that can be used to control the rudder and sails of a sailboat. The reciver can be purchased with the transmitter if you choose to take that route. Purchasing a transmitter/receiver combination is more common when building your own boats.
To power the radio equipment a standard receiver battery is required. This is a battery that operates on 4.8-6.0v. Although a 4 cell disposable AA case can be used, it is highly recommended for an RC sailboat to use a rechargeable battery . The main reason is to ensure the battery pack can supply a sufficient amount of current to the servos. For larger RC sailboats a rechargeable battery is a requirement. The average user would use a 4.8-6.0v NiMh pack however LiFE, Li-ion, LiPo packs are available but be certain to include a Voltage Regulator in your system to limit the voltage.
The most important servo for an RC Sailboat is of course the Sail Servo. The sail servo comes in two different styles that are most common. Each style has its own specific set of advantages and disadvantages. The first style of sail servo that we will talk about is the sail winch servo.
The sail winch servo as pictured on the right hand side uses a drum like wheel to house the sail line. When the drum rotates the line is either let out or brought in. The Sail winch servo typically allows for 3 rotations of the drum with
Sail Servo Winch – Sail Servo – RC Sailboat Controls
torque specs around the 150 oz-in / 11 kg-cm. The biggest difference is that these torque specs are at a relatively short distance from the center point of the drum. This small distance increases the amount of torque relative to the next sail servo type that we will be looking at.
Sail Arm Servo – RC Sailboat Controls
The other Sail Servo style is the arm type . The arm type sail servo uses quite a long arm in order to get an acceptable amount of line draw. As you may expect this operates nearly the same as a standard servo where the only difference is the servo arm itself. For a typical one meter Sailboat, you would require a servo of this style that has at least 150 oz-in / 11 kg-cm of torque as a minimum. This style servo requires more torque then a winch servo as the amount of force produced at the end of the arm is reduces due to the length of the arm.

If you’ve ever seen a remote-control boat skate across the water—or controlled one yourself—you know it’s a good time. These toys can accelerate up to 50 miles per hour, tearing up the waters in your favorite lakes, pools , rivers, and, if you like risk, seas.
RC boats come in lots of shapes, sizes, and styles, but the best models can shred water from afar without becoming sinking ships. We’ve rounded up the best remote-control boats for beach visits, lakefront races, poolside entertainment, and some advice on picking the best RC boat for you.
Stay in play and check out our picks for the best magnetic toys , remote-control trucks , and remote-control planes .
While you can likely get away with using a larger RC boat on a pond or lake, you may want to stick to a smaller model if you’ll be floating yours in a backyard swimming pool or need to pack something tiny. RC boats can be up to two feet long, so make sure to consider the journey to the water, too, especially if the boat you’re eyeing doesn’t come with a carrying case.
The RC boat’s weight helps determine how fast it can move. Heavier boats are better equipped to move at high speeds without capsizing, whereas lighter boats can be speedy using less power, a.k.a., slower acceleration. Think of it like torque on a car (or a full-sized boat, for that matter)—the more power the boat gets from the battery, electric, or gas motor, the faster it can accelerate.
Speed is also dependent on the type of hull—some boats are shaped for optimal turning and curves, while others are built for picking up speed while driving in a straight line.
The priciest models can reach speeds of up to 50 miles per hour. We mostly recommend recreational, battery-powered RC boats that reach speeds up to 30 miles per hour, since the more powerful, expensive models are meant for hardcore hobbyists and professional racers.
Many RC boats have anti-capsize, or capsize recovery, functionality to prevent them from flipping over (and staying overturned). Flipping an RC boat is extremely easy, especially if you lack experience, and can lead to a sinking ship. If you’re new to RC boating, consider grabbing one with capsize recovery, making your boat rebalance and flip back over if it tips.
We researched each model’s speed, customer rating, durability, and unique features. We also consulted buying guides from several top hobbyist publications. We’ve picked options for every type of RC boat customer, whether you’re a casual hobbyist, buying a first boat for your kids, or you’re a dedicated RC enthusiast.
This boat features capsize recovery, so if it tips over or gets hit by a wave, it’ll flip back over to recover. It also has LED lights installed to make it easy to see when it’s dark. Thanks to the autopilot mode that loops the boat into a figure-eight shape, children can easily use it, too.
The R308 comes with two batteries and a charger, with users reporting approximately 20 minutes of power (counting both batteries) when operating the boat at full speed. It has a 400-foot signal range for distance driving and tops at 20 miles per hour. With its carry case, the R308 is a solid RC boat for most users.
This is an excellent option for anyone eager to get into RC boating but unsure of their prowess on the water. It features two autopilot modes, so there’s plenty of opportunity to learn how to use it. It also has an extended playtime of 30 minutes, giving you plenty of time to practice.
With features like capsize recovery, double hatch design, and low-battery and signal alarms, this boat is pretty much goof proof, making it the perfect boat for beginners on their way to becoming enthusiasts.
If you need a well-rounded RC boat, this one has ample protection, zippy speeds, and excellent customer service, all in one attractive package. Its anti-capsize feature prevents it from tipping over, while several users say its nose bumper saved their boats from getting totaled through crashing.
It has an extra battery for more playtime, and several users say it provides up to 20 minutes of action after swapping it. Users who experienced issues with their boats were able to find replacement parts and products thanks to the company’s customer service help. Others say that it’s a terrific value, though the lack of a carry case is disappointing.
This boat reaches speeds of 20-plus miles per hour, making it great for anyone who wants their toy to fly on the water. This boat features a capsize recovery mode, a water-cooled engine, and a double-hatched body, making it easier to control on waves. The charge time is a little long, three to four hours, but it can ride for up to 15 minutes at full power.
Customers say this boat reaches top speed fairly quickly, though some report that the controller is difficult to use and not very responsive. Still, it handles well on the water and is a super speedy boat.
If sailing is your preference, the Voyager 400 is the way to go. Rather than rely on an electric motor to push it forward, the Voyager 400 can sail in any body of water via wind power. Its remote controls the rudder and the propulsion, and just in case wind isn’t in the forecast, it comes with a detachable motor to help propel it.
Customers say it’s easy to use, and everything is sealed to keep interior components dry when it tips over. Its rechargeable remote battery can work for up to one hour, which puts most RC speedboats to shame. A drawback, however, is that if it gets stuck at sea without the motor attached, you’ll have to wait for it to wash ashore.
Cheerwing RC boats are fantastic if you’re looking for an affordable toy to race with your friends. This boat can hit up to 15 miles per hour and has some great features, including capsize recovery and automatic yaw correction, which rebalances your boat. It also signals when the battery is low or starts to lose signal, giving you peace of mind.
If you want to try RC boating without spending much, this is a solid buy. Its biggest downside is in its battery life—just six to eight minutes per charge—and it doesn’t come with the option to buy a second battery, so it requires frequent recharging.
If you need speed and don’t mind investing more money into your hobby, this boat is fantastic. The fastest model on this list, this boat has a top speed of 40 miles per hour, a range of up to 656 feet, and a water-cooled system that prevents the motor from overheating.
It also has safety features to prevent damage from the high speeds, like waterproofing and a one-piece hull to prevent cracks.
The biggest flaw is its lack of capsize recovery, and several users say their boats flipped in action, causing them to swim out to retrieve their toys. It also only comes with one battery.

Three-part video on how to make paneled sails for radio-controlled sailboats.
Sails are the only means to propel a RC yacht that's why a lot of attention is needed building the sails. Anyway it is not difficult to build well cut and working sails. The more experienced the sail maker gets the better the sails work. This guide is intended to help newbies to cut heir own sails and build their own rigs.

The recut seam looked better, wrinkle-wise. I have 2 seams in the sail, at about 1/3 luff and 2/3 luff, trying to get draft into the sail (and some practice with the gadget). I did not recut the upper seam - the wrinkles don't seem to hurt the performance. The Tyvek sail, with 1 gadget seam, looks very nice, and sailed well too.
Step 1: Components. Below is a list of the material used to construct the RC sailboat, most of the items can be sourced on Amazon or a hobby website like Hobby King. Electronic Components. Qty. 1 - Arduino Uno. Qty. 1 - Arduino Nano. Qty. 1 set - RF Transceivers.
Moving forward in a straight line. First, the basic skills. With the boat in the water, start with the wind half way between the front (bow) of the boat, and the side (beam). Keeping the rudder straight, trim (move) the sails so that they are close to the hull (close hauled) and the boat should move forward.

Push the rudder joystick left and right to steer the RC sailboat. Open and close the sails to tighten and loosen the sails, this will increase or decrease your speed. If there are strong winds, tighten the sails so that they don't flop around. Partially close the sails in low wind conditions. It's all about working with the wind and keeping ...
This is a basic demonstration on how to make rc sailboat sails without going to a lot of effort.
Tapering the batten width from the forward end to the after end, such as 1/8" to 3/8" over the length of a 4" batten, will make the leech stiffer at the after end, and ease the transition at the front of the sail. If the sail has been stretched in the leech area by too much either from age, or flogging in strong winds, or having stored the rig ...
The simplest solution is to offset the trailing edge in our software a few millimeters. The mold will then have a smooth taper at the trailing edge that is easy to finish off. Once the part is popped out, the sharp trailing edge can be cut back with a hobby knife, leaving a thin, but durable edge.
An RC Sailboat works by either capturing or redirecting wind energy to propel the boat forward. This is accomplished by the Sailor of the boat placing the sail in the proper direction to catch the wind and at the same time providing a constant heading for the boat to travel in. Steering on the hull is accomplished by controlling the rudder.
Radio-controlled sailboat kits come in different shapes and sizes. They allow hobbyists to build their sailboats from scratch and control them remotely using a radio transmitter. These kits contain all the components necessary to build a functional sailboat, including the hull, sails, rigging, motor, and radio transmitter.
I think it makes it easer to get a smooth finish. Three coats of epoxy ready to complete hatches. Needs buffing to improve the look and feel. Plywood mold to glue hatch frames together with. Plywood jig in use. Plug removed and windows fitted to the frame. Make a RC Sailboat.
TOOLS needed: If you need an excuse to buy tools, then making classic, wooden RC sailboats might be reason enough to get an entire woodshop! But in reality you really only need a few tools, some of which you may already have. Ignoring the smaller hand tools that many already have, you'll probably need to stock up on a few "hobby" tools like a ...
RC Sailboat Controls. side channel, typically throttle on an airplane controls the Sails. Moving the left side stick up or down would draw the sail in or let the sail out. Motion on the stick is vertically. The stick on the right hand side controls the rudder on the RC Sailboat. The rudder channel operates as like any other rudder channel.
Here's how I built the sail winch system in my RC (48" schooner) sailboat. I use a HiTec radio and operate the winch servo with the throttle channel. I also ...
The RC boat's weight helps determine how fast it can move. Heavier boats are better equipped to move at high speeds without capsizing, whereas lighter boats can be speedy using less power, a.k.a ...
