RC land yacht rigid wing working well

[jbrun009]

Would 4 wheels make it more sturdy?

im in the process of building my own version of this. how did you engineer the trim of your wing? is it just one line as a main sheet to a motor and you manualy sheet the wing or is it auto trim?

These links show it in more detail.

Main sheet operates sail angle and trailing edge flap is sort of self operating.

@andyandvirg the tail is auto-trimming or do you manage by a servo ¡?; I'm building a robot multihull and I would like to use this power system.

@elsinidentidad Have a look at these photos

The trailing edge flap is automatically adjusted by the two lines connected to the mast base.

Hahah that's great!

[Freddythethird]

do you turn by the sail or by the wheels?

[andyandvirg]

@Freddythethird Front wheel steers, sail gives more or less power

[andyandvirg]

A few tips. The sail servo needs to be powerful. Rear wheels need some grip to reduce spin outs. It is lots of fun but you need to find a deserted beach front carpark or similar for good  landyachting.

Awesome! I'm drawing up plans for a soft-sail land yacht now.

[haydningall]

Nice! I'm building a similar one. What did you use as a skin to cover the wing?

[andyandvirg]

Thanks. It was some sort of heat shrink plastic bought from a model shop. Cant remember the name.
