Who makes this Eco?

[Meniscus]

I'm trying to figure out who makes the Eco featured in the video below. I have a few suspects, but I thought maybe someone would know or has one.

Well that gets me a little closer, Thanks!

What do you think of the video?

[Jesse J]

I didn't know they had rectangle courses in Hong Kong.

Awsome turning in such a small area. I still don't understand how folks could use stick radios lol

Hi Meniscus. The eco hull is made by Hydro & Marine. Regards

That one has the flood chamber on the opposite side. I'm not 100% sure that's it.

Do you mean the H&M Speedy or the Zip? Both look like the hatch is significantly shorter than the one in the video.

Regarding the hatch, the Hopf looks closer.

:help: Now I'm confused! LOL

What Egneg said leads me to believe that it be matter of preference and what you are used to. Or what you have available when you head out to the pond for that matter! :laugh:

Any other thoughts on who makes this hull? Is it modified from one of these other manufacturers? Perhaps it is indeed the Hopf hull, but a previous version or something along those lines.:popcorn2:

Ecos are big fun.. I wish they were more popular in the US
My buddies in Belgium have told me stories of REALLY fast ones on 4s

:thumbup1: That's the plan! :wink:

:bowdown: All hail the ecos in the US :bowdown:

[marker]

It's definitely a Hopf Super Sonic, the photo of it on the web site with the flood chamber on the opposite side is back to front.( Notice the big number seven)
Naviga has a speed class F1e-1kg for boats of similar size but limited to 1 kilogram weight that are running about 750 watts power, here's an example. The hull is a Kukorelli Lady B.

That Kuko Reli runs insane!
I just sent my 2 toysport jokers in for repair..
I'll be doing some interesting eco vids this summer..

[Meniscus]

SWEEEEEET!!! Thanks guys for the great info and I look forward to the Eco's taking over in the US next!

I can't wait to see everyone's eco setup and videos.

One class that could cross over worldwide wouldn't hurt

So what is the advantage of an Eco over a mono?

[NativePaul]

TURNING, and also they normally self right quicker with their rounded decks.

Billy... Sounds like you are telling me that I should put together my H&M ECO w/ ETTI Hardware I've had sitting here and get it ready for October??? :thumbup1: (Got the H&M because the hull shape is also a legal Mono under NAMBA rules... many of the others weren't...)

Get that rule request in... :thumbup:

I was hoping Steven would move that thread here, but he is a very busy man.

Bill :

I'm building the Hopf Eco with the Etti hardware ( 1.5 mm pianowire ), did you use the
coupler from Etti ? Can it deal with the power ?

Those are the same parts I have... haven't tried the coupler yet... it's a tiny little thing... Should hold up to a brushed setup... Not sure about a "Stock" BL though... One way to find out! ;)

While we are talking Ecos... is there any rule of thumb, etc., concerning shaft angles, balance points, etc?? I've never set one up before...

[Gerwin Brommer]

Yep, there are some "golden rules" for setting up eco's.
I'll try to find'em for you.

[Gerwin Brommer]

Found it.

C.O.G for this eco : between 6.9 and 7.5 inches

[Gerwin Brommer]

hm, why can't I show the picture in a larger size ??????

[Steven Vaccaro]

hm, why can't I show the picture in a larger size ??????

Email it to me and I will try to post it.

[Gerwin Brommer]

" Rules " :

Rudderaxle : 10% of hull-lenght ( looking from the back )
Front op prop : 25 % """"""""""""""""""""""""""""""""""""
Rudderaxle-angle : 90 degr. to driveshaft-angle
COG : where the tubing exits the hull.

That are the basic-settings for any given eco.

[Darin Jordan]

Thanks Gerwin... I appreciate you taking the time to provide that info...

Had something to do with the file being a gif. I changed it to jpeg and it didnt get resized by the forum.

Thank you.

Indeed the ETTI can hold it.
Those ETTI drives are SAWEET eco drives..

Check out these nitro Ecos http://www.toys-port.hu/en/index.htm Then go to purpose
I mean, I know this is Offshore ELECTRICS but they could make for broader understanding.. :sorry:

[Gerwin Brommer]

Bill,

That are no eco's.
They are from the so called "FSR-boats". A racing-class here in Europe.
Do you guys know that class , on your side of the ocean ?
I agree, they look the same and both have fully submerged props.

[BILL OXIDEAN]

Awsome turning in such a small area. I still don't understand how folks could use stick radios lol

I'm not gonna' lie to you.
I TOTALLY miss running stick radios.
:sorry:

If you guys really get involved with ecos, I'll be stoked.
Its a long shot, but it'd be awesome to run it at the nats..
I have 2 and would let some clown drive one..

[Gerwin Brommer]

I love my Futaba T3VC !! :-)
Sticks forever ! :-)

[Paul Pachmayer]

Hi Darin,

Here ya go. .098 flex shaft with just a touch of negative angle, it's also adjustable. Hughey profiled rudder.

Paul.

[j.m.]

Are there any general rules as to the shape of these hulls?

Ideal dead rise angle?
Any width to length ratios?
Length of the straight portion of the keel in relation to the length/radius of the Curved section?
Spray rails? :thumbup1: or :ThumbsDown01:
Size of the flood chamber?

I'm thinking about seeing if I can't design an "ideal" eco (many, many scratch build wooden models for testing), and then get that hull design all over in the US as a sort of one design racing class. Similar to the SV27 class.
