Default Anything Yachting

Hiya..

Notice almost no threads about yachts

I just scored a HobbyKing Monsoon.. very basic, but it was free.

I know absolutely nothing about sailing a boat.. so is going to be a fun adventure for myself and my youngen.

So any other yacht / sail boat enthusiusts around?

Couple of questions off the bat..

-What's the story with the servo? will any servo do?
-How much weight in the keel?

I keen to get this thing in the water, but gotta get it running properly first.

The Monsoon is in full operating order..

cost me nothing in the end..

What i did..

Found an old 29MHz stick radio and receiver.. pulled it apart and made the up/down stick not spring back to the centre.. so fully down the sail is tight to the centre, fully up the sail is as far across (past 90Deg even, so too far). Dont have any end point adjustment so just gotta live with it

Hooked the receiver up and placed into a balloon for waterproofing and worked first time.. stoked.

The servo is a 360Deg Drum type.. seems easy enough

Filled the keel ballast with the guts of an ankle weight.. got about 900g in i think.. didnt measure it... But proof this thing has never hit the water.

All works perfectly.. and ready for its maiden voyage.

Read that they fill the cabin with foam.. cant see the point yet, but sure i will... LOL.. thinking that foam-a-fill in a can? being careful to not go overboard.. BOOM BOOM

No, use something like pool noodles for floatation. Spray foam expands and can keep expanding over time and could end up by blowing the hull apart. You don't want that.
Float test the boat to see where it sits on the water.

Default Ballast

If that's the 1.8m version. 900g in the keel bubble is probably not enough. You need about 1300 to 1500g for light winds and maybe up to 1800g for heavier winds. You can get about 1400g using small fishing sinkers but lead shot is the way to go.

bugger.. I should have weighed it...

I have already aryldited the plug.. shouldn't be too hard to remove.

1.4kg of sinkers will get pretty pricey.. and the shotgun lead shot is pretty hard to come by these days.. I did do the research, but the gun shop owner says everyone just buys premade rounds now

I take it if it is too little amount it will tip over easier??

Is there a way of putting a different keel bulb on from a different boat or a universal one??

It can get pricey. I used size 2 or 3 round sinkers, cost about $20 in the end I think.

I know some people make moulds up and use solid lead keel bubbles which is the best solution. You can buy the bubbles from hobby king.

The problem with not enough weight in the keel is in a strong breeze, you need to let the sail out so it doesn't tip over, however, it still tips and the boom will trail in the water which acts like a rudder and makes it hard to sail if that makes sense.

cheers for the reply..

I would love to purchase a pre made lead bubble.. looked at hobby king but couldn't find one..

any idea of where to get one from?? I will continue googling.

In the meantime I will purchase another hollow bulb from hobby king instead of trying to open up the one I just wrecked.. and find some lead shot from a sport or gun shop

Ballast Sorted..

Lead buck shot...

Chipped the Aryldite out real easy and changed over to the lead
went from 700g (i was shocked) of the ankle weight to 1450g with the lead shot

got it from the chick at the camping shop, they didn't have any in the shop, but her husband used to load his own shells and had some in the shed left over from years ago.

Free..

All glued and reinstall, ready for the maiden voyage
