ECO Class

[CornelP]

Hi guys, I recently ordered an Eco hull (Rush Evo, copy of Sonic Evo), 51cm long.
I intend to build it and maybe race it this year, if everything is ok...
My only problem is: any good tutorials on Eco setups? I have been looking around and I could not find anything... submerged drive is quite new for me (still struggling with surface )

Thanks

Cornel

Look toward some euro forums. everywhere else in the world races eco but US I don't know whats wrong with these guys here, somewhere down the line they decided boats under 23 inches simply cant be raced

I particularly love ecos but mine are all set up at the factory by toysport.

Etti makes the sweetest eco drive

Will do, maybe Gerwin knows a bit more, now that i think about this...
Thank you

Yeah, that guy seems to have a broad spectrum of knowledge..

everything is in millimeters, hull is 500 mm long.
So : rudder at 10%
Prop at 25 %

THANK YOU!!!
When I'll get the hull, will start a build thread...

and people wonder why RC Boat Racing is not more popular in the US. When Newbs see that you need to spend over $1000 to have a semi competitive race boat, they tend to get turned off..I would love it if more people Ran ECO! would also bring more people to the hobby

[CornelP]

Well, my estimated costs are:
Hull: 130$
Motor: 70$ (Feigao 14S)
ESC: 60$ (Turnigy Marine 60A)
Driveshaft/Rudder/Prop: 70$ (nothing fancy, rudder home made)
Battery: 30$ (2S 5000 40C, HK)
Radio: 110$ (Spektrum DX5)

Total: 470$ for something you can actually race... and have loads of fun!

I too have been looking for this info so I can properly convert a Foki SX to eco. Thanks Gerwin, I'll try to get this translated.

Cornel, I'll be watching your build!

Gerwin, that was interesting reading but I'm looking for more info on eco setups. Info dealing with measurements from COG for different hulls and hull types, etc. If you know of such a link, please share! Thanks, Sdg.

Hey buddy, you wanna' be part of my campaign to reduce the size and cost of FE?
All y' gotta do is play with smaller boats, post pics and vids, and have a great attitude about it..

I like big boats as well as the next skipper but the push from the power supremacists mmade huge length restrictions, monster power even in the smallest classes and all around expensive running.

A competitive N-2 mono is over 1,000 bux to get into..

Ya know I've never seen two of these in one place. I don't know of any conspiracy to get rid of small inexpensive stuff. The ECO's just never captured the imagination of the US guys. Still have no idea why. I've never seen a heat raced. Not even at a nats. Go figure.

[Gerwin Brommer]

Sundoq.

The 10% , 25% etc etc rule, works for all eco's, as a basic setup.

[sundog]

You'll have to excuse my ignorance; 10% and 25% of what? Total length of boat? Waterline? From center of gravity? I could make it look like the diagram, but I have a feeling rudder placement is critical on ecos, after seeing how fast these boats turn!

[sundog]

Guess Gerwin is indisposed at the moment. Anybody else know about this 10%, 25% rule he was talking about?
