    Latest vid (edited down from around 12 short vids) of sailing at the bus park . Winds about 20knts in gusts, but a few good runs. About 1 hrs' constant sailing on this outing. Looking at making a new sail when I have the time, to see If I can get better performance.

    Still making small improvements in the quest for speed. Having a good strong steady wind is still the main problem, as the carparks don't get a clean wind. Had about 18 knots a few days back, and managed to get a short run of 28kph (GPS) which beat the previous best of 21kph. May need a taller narrower sail or the mast moving forward a bit, to get the center of effort forward, as it drifts in a straight line in a high wind.

    Tried the larger wheels, but they seemed to need a much stronger wind to operate with them. They may need bearings adapted to them to make them run more accurately. Gone back to the smaller wheels. Also changed the mainsheet to the end of the boom for less load on the servo. Sail doesn't go out as far for downwind, but it doesn't seem to matter.

    Vids of short 28kph speed run (first run back) and drift/crash in big gust, (kerb got in the way)

    Axle's done, wheels painted and fitted and ready for the car park this weekend (if it doesn't rain) or the beach if there's any sand left. Added some Dynema braces for the axles as well to prevent bending by hitting a rock /hole/ kerb etc

    Also a pic of the beach after the latest storm. All the money the council spent dragging sand back up the beach with scrapers has once again been wasted. The new rope and pole planting was another waste of money, as the front row of poles is now hanging down to the beach (washed out after I took this pic).
    The council refuses to put rocks on this stretch, despite it being washed out every year, (with them spending $100k + /yr on re-establishment) and all local residents demanding they do. Morons ! - and people wonder why the rates are so high ! The rocks on the right hand end stop most damage as can be seen, fairly obvious solution you would think.

    Wind was a steady 44kph when I took the pics, had been up to 130kph in some areas in Auckland. Unfortunately too much rain and salt spray to try the yacht,- might have been interesting !

    Owing to the amount of camber on the rear wheels which reduced the ground clearance, causing it to get get hung up on certain objects, I thought I might try some larger wheels to increase the ground clearance to round where it was previously. After adding the camber, the yacht would no longer run on the playing field grass, but was a lot better on the seal.

    It ran quite well on the beach, but the rear wheels were a bit too thin, and tended to sink into the sand, creating drag and preventing it tacking well, and needing to be gybed on the turns most times. I spotted some larger wheels in the big local hardware store (130x20 as against the 100x12s on it at present) which looked like they might be worth a try, so bought the last 2 there.

    Spent a few hours this evening making up some new stub axles for them, and just need to fit them to the axle tube (or cut a new one,- probably easier) and through drill them for a keeper bolt. The wheels are a bit heavier than the 100mm ones, so will add a bit more ' un-sprung' weight, which will act like ballast and improve stability. Hopefully they will work better on grass and sand compared to the 100mm

    The centers in the 130mm wheels are maybe big enough to bore and fit a couple of small bearings, which would make the wheels run smoother and more accurately. Will wait to see how these perform first before I worry about that.

    A bit more fun at the carpark with a bit of 'cross country'. Still no decent wind for another beach run, but at least it's getting some use.

    Certainly a lot of fun Phil,- looking at some larger wheels for the 'stern' same type just larger. With the camber now, it handles better, but it's a lot lower, and it catches on things, and won't run on the sports field grass.

    Hi FB, handy that it's a no exit dead end loop in the carpark, as nobody seems to use it in the weekends/holidays. During the week the whole park is chocka with cars outside it everywhere as well, so it's great being able to use it. Only thing is, it's on a 10 deg slope which sort of kills the run one way unless there is decent wind.

    The 3-4ft median plantings disturb the wind as you can see by the sail thrashing round in all directions, but beggars can't be choosers. Might have a look at the even bigger park and ride carpark about 15km away, to see if it's as empty in the weekends.

    Hi Trev, good part about it, is I don't have to drive for miles to a pond. I have almost given up on trying to run my boats at the local one (12km away), as I can drive all the way out there, only to find the local yacht club racing (all boring $$$$ one class boats) and not really wanting you there. Used to be only afternoons 4 days a week, now they are monopolizing it most days.

    Seems to be mostly people who can afford $1000 + yachts which most kids who might want to sail can't afford. There are no open classes for beginners, but even in the smaller one design classes, adults would just outspend kids and put them off trying. Most of the guys racing are over 30/retired etc, carpark full of SUVs BMWs etc etc, and we wonder why kids aren't interested when they see that. Used to be a family hobby.

    Made a new slightly longer (80mm) rear axle which has the wheels cambered, and very slight toe-in. Works quite well and is a lot more stable on tacks and gybes,- doesn't fall over as much now, just drifts instead. Good wind but the tide was in, so the bus station it was. Wind was the wrong direction there, but did the job for the test..

    One of the things I'd like to try is a wing sail, but they need to be a bit techo to work properly. I've seen a UK built all metal full sized land yacht with a wing sail, with an adjustable leech section, which has obtained some pretty impressive speeds. A bit hard to do the same in miniature though. Something to look at later.

    I did attempt to make a wing sail for a 26" free running catamaran around 1968(before I bought my first TX) but it wasn't that successful, as it had a symmetrical aerofoil.

    Finally! some good wind from the right direction to try the yacht out on the beach, Sand is very sticky still and a bit soft, (last cyclone ruined the sand with tons of silt from subdivisions up the estuary) so the speed and tacking wasn't great and pointing was non existent. Ran it constantly for around 40 mins and covered 3.48km at a max recorded speed (not constant) of 21kph (would have been far faster on asphalt) The distance is further than you can see in the vid, from the cliffs at the southern end to the hill at the northern end so it did quite well.

    Fell over a number of times due to the sand stopping the turns, but I got a lot of exercise walking up and down the beach, righting it😁 The mini keychain camera worked well and ran for around 50 mins before I unplugged it. It has been modified with a Nokia phone battery on a lead for longer video time, (original tiny built in batteries only gave around 30 mins max when new, and this one had died after about 12 yrs of using the cameras in boats and planes. Picture is not brilliant but does the job.

    Mainsheet block has now been modified to stop the sheet riding off the pulley, (a handy thing with vids showing problems you may not otherwise see.) The beach should be better in summer as it dries out quicker and is harder when the tide's out. The yacht got slower towards the end, and wouldn't tack, so had to be gybed to turn round every time, as the tide was coming in and the sand was softening, plus it was getting cold.

    Lots of fun all the same but the quest for more speed goes on.

    JB

    Thanks for the kind comments guys, it was great to finally get on the beach and give it a go. I'm surprised that the 'temporary' art card sail is still hanging in there after all the thrashing it's had. Eventually I'm going to use the rip-stop nylon to make a proper battened sail, which should have a better shape and be a lot lighter as well.

    I'll use this sail till it dies as it seems to work pretty well, (will tack and point much better on tarmac) but I don't think a nylon sail would be much better on the sand, which just too sticky and soft at the moment, The spring has sprung so summer's on the way! (also keeping my eye out for a huge concrete area.)

    Almost had some good wind today, (been waiting for weeks) so went down to the park and ride to give it another crack. Super gusty as usual due to trees etc breaking the wind up, but a bit stronger than last time. Last run at the sports park was slow, -clocked at 14kph (GPS) but more like 20 today on one run up the park. Still waiting for the perfect day on the beach for some decent speed trials, (bit dodgy going too fast with kerbs all round, easy to break things.)

    I've made some improvements to the steering head with bushes to reduce play, (drilled out the steering head both ends) and it now steers a lot better. The bushes are a bit firm, but the 20kg MG digital servo has no trouble with it.

    Just in the process of re-modelling the rear mainsheet catch dowel (as mentioned earlier- increases inhaul by changing the mainsheet angle) as it was a bit short and the sheet was slipping off when sheeted hard in. I'm lengthening it, and notching the Formica servo arm to clear it. Always improvements to make for better performance. Hopefully more speed next post.

    Hi Peter, I'm hoping to run it on the beach when the conditions are right, but I need an Easterly wind, but we have had virtually nothing but Westerly storms for months. There was a good Easterly a few weeks back, but the sand was wet, tide was half in, and it was raining.☹️😠 Weather's warming up slightly, so hopefully it will swap round to its' usual good onshore wind.
    It looks reasonably fine in these vids, but I ended up racing to get everything in the car, as a huge squall came through with about 1 mins warning. Typical at the moment. see pic - hosed down
    Second run would have been faster if it didn't have to run up a 10 deg slope.

    Fine and had some good wind today, but from the wrong direction again, although a bit more SW. Still coming from behind the hills/houses, so not much good. Took around 12 tries to get this much video. It would just start going well and the wind would stop or change direction 90dg. Tried on the beach but the same thing, as it was coming over a caravan park with big trees,- gusty, swirling and inconsistent. Has to come right soon??😐

    Another small addition added to prevent the eventual salty sand 'spray' getting on the underneath. Just a small flat ally strip. clamped onto the front axle with a brass strip, and secured from tilting with hotmelt glue. Also added a dowel to the front of the front hatch, as it kept popping up a bit for some reason (was a tight fit with a magnetic catch at the back) - frame may be flexing a bit under strain.

    Still waiting for the right weather, -yesterday wrong direction and not enough, today almost cyclonic winds and heavy rain early morning, rain most of the day, - now rain and moderate wind😠. Perhaps I should take up chess,- at least it's not weather dependent here like model sailing.😐
