Rear axle next, easy!
small hole marks axle centre point.
Dab of Hot Glue under the axle and nail varnish thread lock.

Next the mast.

I used nail varnish again... just in case!
I used the longer section as the lower end where the higher stress is.

OK so I know nothing about yachts, mast, booms, etc....
I know that but just to emphasize that, there's nothing in the manual about fitting the boom!   {:-{

Lets see if I can figure this out...

Nope!  Shouldn't the boom be connected to the mast somehow?!?!?

Martin, the tack of the sail (the bottom front corner) has two tabs.  You have them both round the mast, one should go round the boom.  The end of the boom with the screw is the outboard end.  The end close to the mast has a hole for the cocktail stick which goes through the hole in the tab.  The small rubber band holds the sail to the outboard end of the boom.

Well, that is how Hobbyking "designed" it as far as I can figure.  But it's rubbish.  The sail will never set properly without tension kept on the foot and luff and something to stop the boom flying up in the air.  My solution is earlier in this thread but there are certainly others.  By all means try the rig as designed - it works after a fashion - but it'll need some work if you want it to give continued satisfaction!

Good luck!

Greg

Cracking close ups Martin, the writers of the build manual could learn a lot from this -
my philosophy 1 photo is better than a hundred words !
the model should go really well, minimum component parts hence lightweight = speed,
looking forward to the movie !

On a recent Scrapheap Challenge they built land yachts and quoted
in a 20mph wind a dinghy would travel at 12mph and a land yacht 30+mph.

Need a big empty space to test it, the acceleration is unbelievable 0 to flat out in an instant !

Ah! Cheers Greg!    :-))

I've also found these photos:

So THAT's what the toothpick and rubber band are for!!!

Right, good! Just make these modifications and were good to go!
..... Do we think these tires will provide enough flotation? Or will I have to wait until winter and the water freezes over?!

In case anyone has never snipped off the long end of a zip tie, the cut end is hard as hell and twice as sharp. Been there, done that.

Actually fixed the boom up last week and then had to wait for the right weather! Had it's first run last night in Tesco car park, great fun! ..... there seems to be a lot of walking involved with a Land Yachts!!!!

Full report once I've edited the videos.

Hey Greg!

I know very little about yachty things, could you elaborate on:

1. "to try and improve things a bit"
2. "boom vang to keep the boom level"

Ta!   :-)
 Martin



Not sure if anyone is interested but just in case...

Here's what I did to the rig to try and improve things a bit.  There was no room for a conventional boom vang to keep the boom level, so I went for a windsurfer-style wishbone arrangement.  All bashed together out of whatever I had to hand, so it's a bit rough and ready, but if it works OK I can tart it up a bit later.

(Come on Martin, where's yours??)
