Or the screw. The screw. Man, the screw. Why do we make some things so stupidly proprietary.. Like the whirlwind screw.
I guess they saw a market for replacement screws at a pence or two.


This winch is really not worth it, but the offer's on the table.
Of course I will take it! I will make you a deal. If I get it working I will send it back to you. If not, I will keep it for parts.

Hah,
Well, I can Garuntee it's hopeless. Standley took it apart a few weeks ago and read it it's last rights.
It was inside a boat that was side-swiped by someone else in one of these "all classes sailed" type things and went down to davey-jone's locker. Then sat in a basement for a few years.

does that change anything?

If Standley took it apart and pronounced it dead, I have to respect that. Damn, I love to fix things.

Yup, Bummer.
Finding a replacement winch for it was a bear. Stinks we've lost the mid-grade market.
It's more or less Hitec or RMG, no in-between.



Anyways if you want that stuff, it's yours, but it's probably better off in the dumpster. (I recycle all electronics by the way, might as well.)

Winch sources


Breakwater,

Consider the old Don Prough/Dumas. Buy about a dozen of them and get to some time on a milling machine and lighten the plates and gears with mucho lightning holes.

So much backlash they consume very little power.

That's actually a great idea.
those are good winches, and fit the bill for the "midgrade" winch, not total junk Hitec, not pure-gold RMG

The boat this whirlwind came out of is a boat from the 90's that isn't going to win any world championships anyways, so that winch is more than suitable for club racing.. The whole goal with this peticular boat is to build the club.

Love RC Yachts!!!
Honestly, buoyancy foam is a band-aid solution to a fundamental problem....
If the boat is taking water inboard, why? A lek in the hull, fincas, mast tube, o deck fittings is easily traced and fixed.

If its a leaking hatch, if it can't be sealed or fixed,just use sticky back. It's cheap, and works 100% of the time. You can reuse it numerous times before it needs replacement( and its cheap anyway). Sometimes I realise that thin hulls may pump when sailing, sucking in water. In that case a 1/8" breather hole in the bulkhead, or a thin tube from the deck will help with that.

And besides, 50 grams or so of potential corrector weight is lost, and only gives moisture something else to form on....

Well,
Bigpat is right. Before you address adding buoyancy, it's better to look at the boat from the perspective of WHY are you adding buoyancy and try to correct that problem first.

after that, if you must, those airbags seem like a better option.
You never want to add anything, unless you have to

Leaks and winning races


If one makes a careful study of what is required to win high level M class regattas, you will find that consistency is terribly important. I believe we concluded that having a breakdown-free Nationals was worth the difference between 1-2 places in the standings in a typical Nationals. That means things being equal, a leak free boat that is in the hunt has a much improved chance of winning over less reliable competitors.

We took it a step further and declined to use a film covered deck like some of the light weights of the day because one collision, even if you were not at fault, could lose a regatta.

Fitting flotation is, to me, closing the barn door after the horse is gone if one expects to be truly competitive.

I for one can attest that you WILL NOT win a race when your sinks. It is slow.
