Quite a variety of styles and sizes, including 1/2's. I offer this for your reference if you are interested. I have no actual experiences using their plans.

Here in Washington (state) the Seattle area was once highly prominent in unlimted hydroplance racing and still hosts the annual "Seafair" races featuring not only unlimiteds but the lesser categories of hydros.

The "glory days" of hydro racing featured the gloriously loud piston engines like Allisons, Rolls-Merlins and Packard V-12's which, for the most part, have now been replaced with turbines with their own unique sounds. They're not the same just different.

Seattle was once the home of the legendary Bill Muncey who, until the time of his death in a 1958 crash, was argueably the "King of the Unlimiteds" and there are several others
prominent in the field today; Bill Villwok for example.

So model hydros were and are popular here in the Pacific northwest where designers like Ted Jones live on as well as the drivers like Muncey live on if only in name.

That first one is lovely.
I never really got into boats having enough fun with planes,cars and helis.
But a .010 powered airboat would be cool.

Boats DO have their attractions especially in area like ours where there is an abudance of good places to run them in both fresh and salt water. With the development of compact and reliable RC equipment, RC model boats are even more appealing though fresh water is my preference due the to corrosion from the salt.

Model boating is just another dimension of our multi-faceted modeling hobby.[/wow]

Dave just wondering if there is at all a speed difference running in fresh or salty water i imagine salty could be faster because objects float better in salt water so have less resistance.

Aside from the bouyancy factor you mention I would see no difference between the two.

Ok i was just wondering and i wonder a lot Smile

Used to go to the Columbia cup over in the Tri-citys area (Kennewick/Pasco/Richland). What a party that was!!. The Unlimiteds would fire up and everyone would wander out into the river waist high, drink in hand, and cheer there favorite on.

Some of the crazy inebriated folks would float right out there with there head and drink just above the water. I don't think they realized just how far that turn fin reaches down into the water. Shocked

There barely touching the water at speed and with gobs of HP, the salinity wouldn't have a noticable effect.

sounds a bit like the boating equilivant to this,

AS PV suggests, unlimited hydros are flying more than they are floating.

Anyone who has ever witnessed a "blow over" can verify that. It happens fairly frequenty in unlimited hydro racing. It's for this reason that the APBA now requires an escape hatch on the BOTTOM of every unlimited hydro in competition. Many drivers have been saved by going out the escape hatch after a flip.

Once heard the sound of those unmuffled V-12's is never forgotten.

I have a old MRP Miss Budweiser with double brushed motors and v-drive setup. Also bought a Hydro Zeta water cooled electric speed controller with it, and ditched the mechanical switch speed controller setup.

Was pretty quick at the time (mid 80's tech).

Seen this the other day and thought it was a pretty good deal for a almost RTR boat.

Purchase here.

Really cool one, all the effects of the real deal.

Unmuffled V12 lovely you are getting me interested now imagine an rc one using this engine.

What a noise for an air engine, it's a jewel... And has it's price! I found it on eBay Shocked

i actually like this one a lot too.

ideeman1994 Sun Oct 09, 2011 2:25 pm

What always impressed me was how those teeeny engines could swing so big proprellers Shocked

Yes they do but i also have a 0.009 engine that swings a 5 by 3 cox prop.

You should post a video on your channel with this engine, I'd love to see it!

I'LL try their is a pic of it in my album it is called the Bamby.

ideeman1994 Sun Oct 09, 2011 2:37 pm

I found a Bamby engine, but it looks more like a diesel to me...

it is diesel where did you find it?

ideeman1994 Sun Oct 09, 2011 2:41 pm

Ok, I thought you still were talking about a CO2 engine... I found it on your personal gallery Wink

Oh ok i thought you found one for sale.

The differences in navigation is very low.
The buoyancy in salt water is better for anybody boat and even as much more salt the better.
For the engines and electronic salt is death.

The extra salinity might cause a slight difference or extra drag/traction in the corners, when there inside sponson turn fin is digging in, throwing that big roostertail and the outer sponson is dragging thru the water, but it would probably just show up as a slight blip on the average lap times. It might also be a bit rougher ride due to the extra mass of the water.
