2026-2027, Rules and regulations for the Radio Controlled OZ Land Yacht

These may ules vary over time…

Building restrictions:

Make one from what ever you want as long as you follow the guidelines on sails and general size and weight restrictions. 3D printing is an easy and versatile option with some fantastic starting designs available online. See our Blog for building ideas.

As the yachts MUST have DF65 sails, our rules are a little different from those in the past.

Max Length: 650mm. This is measured from the front of the steering tyre, to the back of the main body. This does not include the optional backstay bar.

Max Width: 500mm. This measurement is taken from the outside of the tyres across the yacht. If you change to wider tyres, you must use shorter axles. With this in mind, it is a good idea to make it easy to change to different length axles or hubs when designing the yacht.

Sails/Rigs: This is the most important restriction. You can only use sails that are used on Dragonforce 65 yachts. You can use DF65 C, B and A rigs MAINSAIL ONLY! You can use an A+ rig but you’ll need to add an additional forestay swivel point and possibly a longer back stay support. No other sails are allowed. You can make your own as long as they conform to DF65 rules. You must use a DF65 Mast/Boom with each change of sails. The DF65 boom allows you to add twist into the main. We normally sail DF65 water based yachts and simply remove the jibs, and then with minor adjustments and removal of the jib, the rigs fit straight on to the land yachts. PS: you are probably mad to use an A+ but what could possibly go wrong….

NOTE:you can re-cut any DF sail smaller, but you cannot make a set of sails larger than DF65 sail rules.

Wheels/Tyres: Any type of wheel or tyre can be used. Any type of axle or bearing may also be used. We suggest 8mm roller blade bearing for easy supply and suitability. There are other suggestions in our blog and on downloadbable files and original MUSHU post.

Weight: 700g Weight of land yacht including all winches, battery and wheels. (Excluding DF65 rig. The DF65 rig (mast/boom/sail) is an additional weight and will slightly vary with the rig size.

Height: There are no height restrictions. The height is principally governed by the DF65 sail configuration you choose. It is better to design the body of your boat with a low centre of gravity.
