What our customers say about Racing Sparrow

Being a complete novice, I purchased your book a couple of years ago and built two racing sparrows. Building on this experience I then went on to build, from scratch, an IOM (Triple Crown design).

I've since joined a local club and sail virtually every weekend. I would just like to thank you for your endeavours which have allowed me to enter a world I never thought was in my reach.

John Sterland, Australia

Coming upon your book, "Build your own Radio Controlled Yacht" in the Napier Public Library, I am hugely impressed.

The combination of your superb photos and illustrations with your easy writing style make it a standout publication and I hope it does well for you.

Richard Spence, New Zealand

Thanks for an excellent design in your RG65. I trialled her again today in a solid 20 knots gusting higher. Even so in a steep chop and fingers off the rudder she drove upwind remarkably well, balanced perfectly.

Very impressed that a model boat can handle that with a large rig. I found the book excellent. Ive built several big boats, plus a few skiffs and without that resource building such a good boat would have been impossible.

Kevins rg65 model yacht with stripy wood in dark light alternating pattern, Location: 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.

A free sailing model yacht made from cardboard and cellotape, apparently it sailed quite well for 15 minutes! It was 375mm long and had a proper weighted keel and working sails.

Take a look at the blog section for a full write up about this model.

More about Racing Sparrow

What is Racing Sparrow and who is Bryn Heveldt?

When I was nine years old my father, Ross Heveldt taught me to sail down at Bucklands Beach in Auckland. My wee optimist dinghy was called 'The Racing Sparrow', the nickname my uncle Bruce Curry gave to me when I was a small boy. Apparently I had an abundance of energy.

I studied at Whanganui School of Design and have been a designer / developer since 1998. I live in New Zealand.

Best wishes and happy sailing, Bryn Heveldt.
