Build Your Own Radio Controlled Yacht

This book is designed to help you build a RacingSparrow 750 from scratch using minimal materials and a very minimal tool set. When you buy the eBook you download a PDF version complete with detailed plans, clear illustrations and photos. It lists all tools & materials and shows centimeters & inch measurements. 

Are there other plans I can build?

You can download these plans for free , 7 differing sizes and designs.

The techniques and materials detailed in the book can easily be adapted to the other plans to get a boat that suits your tastes. Along with the RS750 the other very popular boat is the RG65 designed RacingSparrow. The RG65 can be used to race and measures within the rules.

How much does it cost?

Some modellers manage to build for as little as $50. This might be someone who has some of the materials already or are good at repurposing old things. The authors boat cost around $300 including the radio gear. That was for all the materials described and used in the book.

Common questions

Is the book translated in many languages?

The original book is written in English. You can also buy translated versions in French and German.

What radio gear do I use?

For a radio-controlled sailboat in 2023, you need a transmitter, receiver, 4xAA battery holder, and 2 servos (1 for sail arm, 1 for rudder) that plug into the receiver using JR connectors. Waterproof options and different servo sizes for sail arm and rudder are abundant. You can choose from a range of transmitter and servo options, from simple to high tech.

Futaba Sail Arm

The simple setup NZD$70(cheapest):
Transmitter & Receiver
Servos x 2
Battery Holder

The mid-range setup NZD$230 (all waterproof):

The no-limits setup: NZD$720

Is it that hard to make a boat?

Is pouring lead within my skillset and safe?

How much does it cost all-together to build a boat?

The radio gear and servos will set you back a few hundred, depending on what you end up buying and what needs you have. To start the project however, you really only need the balsa to build the hull. This will keep you quiet for some months. I'm willing to bet in that time you will spend time on the internet choosing components for your yacht including radio gear. You will need things like paint, resins and cloth, small aluminium lengths, lots of small and cheap parts which will add up. Most people doing this project may already have most of what they need. The toolset required is very simple. No specialist tools are needed. A craft knife and ruler will get used the most. You won't need to buy any special or expensive tools.

A budget between $300-500NZD would be realistic, this is spread out across typically a 6-12 month project. Fitting this in between the rest of your life!

Kevins stunning RG65, New Zealand

Hi all, Just finished an RG65 racing Sparrow. (I made an 80% size one a while ago, it's in the gallery).
Standard hull with 1 layer of 50g glass and epoxy. Deck is 1.5mm balsa with veneer strips on top. Single hatch with rubber seals and 3 hold down screws.as I fitted the rudder servo into the recessed rear deck. Corona servos DS339HV digital for the sails and CS939 analogue for the rudder, I fitted a greased cork gasket under the rudder servo arm to waterproof the servo. Battery is a 2S 1000mAh lipo with a regulator for the Rx and rudder servo. Radio is Flysky CT6B. laminated ply fin with 2 layers of 50g glass, rudder from balsa with 1 layer of glass. Ballast and fin is 680g. Mast is slightly taller at 1050 so the sails are slightly different to fit within the 2250cm max. All up weight is 1150g.
I'll get sailing pix very soon.

Bryn's fibreglass Racing Sparrow, Wellington, New Zealand

This red boat is the latest racing sparrow that we've built and put to the test. It has been built for wellington conditions. It has the maximum 1.3kg lead bulb. It has a basic deck structure, no plywood, 1 layer of balsa with a coat of resin-only to save on weight and budget. It uses the more basic hatch construction of plastic sheet taped on with ducktape, very effective and waterproof. The sails are maxed out, being cut very close to the plans, maybe a little bigger, there are no rules about max sail area in the class rules! Another difference on this boat is the mast has been painted black for a different look.
