Who makes this Eco?

**Meniscus** · 05-27-2009, 02:41 PM

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** · 05-27-2009, 04:10 PM

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

I started on stick radios and went to pistol grip - took a while to get used to the wheel.

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.

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!

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.

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

That's the plan!

All hail the ecos in the US

**marker** · 05-27-2009, 07:29 PM

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** · 05-27-2009, 11:13 PM

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.

**BILL OXIDEAN** · 05-27-2009, 11:38 PM

Toysport Joker (race)
Novak GTB 13.5 system
Maxamps 6,000 2s2p
Airtronics M11 2.4 radio and servo
Graupner 31mm prop

Good for 33mph with no hull mods
You guys have got me all jacked up!

Looks like NAMBA keeping eco was good let's see if we can slide a BL/Lipo
suppliment into NAMBA's Eco rules NOT to become a heated debate , just a suggestion..

One class that could cross over worldwide wouldn't hurt

I already proved the euro boys wrong when they said I couldn't bust 28mph with an eco on 7-zellen and a 19-turn motor

http://www.namba.com/content/records.asp?EventType=11

Me hit 31 LoL..
On 6-zellen
Ecos rock don't knock it 'til you try it..
Turn like the movie TRON INSANE accelleration Self righting, what more do you want!!!

Great analogy! You've got that one right!

Eco's , sold in Germany : http://www.gundert.de/ka6.htm

**NorthernBoater** · 05-28-2009, 12:56 AM

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

**NativePaul** · 05-28-2009, 02:28 AM

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

Sweet link Gerwin! Thanks!

My son and I are building a Hopf-Sonic.
Summer is coming, I think my son soon will ask me when we will finish his boat :-)

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???

(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...

**Gerwin Brommer** · 05-28-2009, 11:36 AM

Not the cheapest one, but boy o boy does he/she look neat ! :

Yeah, I posted some videos here: https://forums.offshoreelectrics.com/...ead.php?t=7054

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

**Gerwin Brommer** · 05-28-2009, 12:47 PM

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** · 05-28-2009, 02:06 PM

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

**Gerwin Brommer** · 05-28-2009, 02:19 PM

Found it.

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

**Gerwin Brommer** · 05-28-2009, 02:36 PM

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