Concept EP or Ikarus Eco 8?

Which one?  How is parts availability from Hobby Lobby, I would assume that
Concept EP parts availability from Tower Hobbies would be excellent.

I dont  own any  of this helis but some time ago I was thinking about buying
an electric heli. The conclusions that I took at the time was that Ikarus is
superior in any aspect. Either if you want to fly  a stock one or doing some
tunning, the Eco8 has much more space to explore. As to parts availability I
in those stores I dont know, but Ikarus has its own site on the web
http://www.ikarus-modellbau.de/Ikarus/english/index-e.html .

Hope this helps,

I currently fly both helis.  The EP is ok, and thats the best I can say.  Parts
availability is excellent from Tower and HobbyTown both, but in honesty, the
heli just isnt refined enough.  Its been around for about 12 years now, and all
they changed was to the newer kit which includes the longer mast, larger servo
mounts and better motor.  It has cost me quite a bit of money to get this heli
flying decently on power for about 5-7 minutes.  Im not depressed by it though,
as it looks great in those scale bodies you saw!  One thing true also, is that
it is smaller than the ECO, making the ECO a steadier heli to fly.  
Now with the ECO, using a cheap $20 RC car motor on 8 1700s, I can fly about
7-10 minutes, loop and roll!  My EP Concept required a $50 motor, and still can
barely loop once in a flight.  The ECO has a much more efficient drivetrain,
easier to maintain, cheaper parts, and parts are easy to get.  I use RC Direct
out of California who stocks WAY more than Hobby Lobby.  Check them out at:

I also now have the scale body for the ECO and it is wonderful too.  My buddy
used to have the ECO with a brushless motor and we used 10 cells...WHOA!  It
could do all the 3D manuvers and those guys at the Silver Bowl dropped their
jaws in awe.  It saw about 10-15 minute flights, which is something the EP
never will.  Plus, the ECO has actual upgrades like a metal swashplate,
autorotation gear, graphite frames, carbon blades, aluminum stiffeners....and
the list goes on.  I have also flown and owned the Kalt Whisper and thats the
same boat as the EP.  The ECO is definitely the best choice around.  Good luck,
and let me know if you need anything.  Oh, hows the LMH?

The Eco every time! I've had both (and a Whisper, too!) and the Eco is far
and away the best machine. Try and use CCPM, if your radio supports it, as
the mechanical mixer can be a bit sloppy.

LV RCFlyer:
    Duh, the autorotation gear is a +$40 option on the Eco 8/16 but is a standard
feature on the EP Concept.
If you are interested in hop up parts In August Kyosho released a full metal head
option! Also there are aluminum shafts for the tail, feathering, and also the idler
shafts for hop up parts, and also a carbon fiber tail boom. There are several asym
and sym wood blades. If you ever looked at the two frames closely you could easily
see that the EP can take a lot more pounding than the Eco 8 frame.
    Tell me, what $20 car motor works in an Eco 8 ! It won't last long at full
power on 8 cells ! My EP flies fine on a $23.99 motor from Hobby Shack, Trinity Gem
2, (regular price is $27.99). It would probably fly just as well on the $15.99
cheapy motors. If you bothered to check the hard core Japanese fliers who have
heavily modified their EP and ECO 8 helis you can see their data for efficiency of
the respective gear trains.(note you have to have a browser that supports Japanese,
also you might want to have either a Chinese or Japanese proficient person explain
the results to you.!)

(on this page you can see that the Ep only need 101 W to hover,vs 140 W for the Eco
8)

Sincerely
Peter

Thanks for the enlightenment.  Im sorry you obviously took offense to my
opinion.  The only problem is you speak from what others have known, not from
personal experience.  Which heli has the better flyability?  Which heli handles
stronger winds?  Which heli needs the foam blades replaced with $40 wood
blades?  Yes, the auto gear is $40, but we knock that out with the wood blades.
 Plus, the cost.  ECO and motor is $225.  EP and motor ar $350...PLUS you must
replace the stock motor for a minimum of $16.  Oh, as far as autorotations, the
EP doesnt do it very well.  The larger, heavier ECO autos very well....and I am
not the only one who can attrest to that.  I enjoy both my helis.  But, bigger
flies better.  Im not knocking the EP concept, but antoher thing is the abuse
tolerance.  The EP is tough, but the ECO looks weak but handles a lot more
abuse than you would expect.  This unfortunately comes because you have not
personally seen or abused the ECO itself.  As for the Japenese numbers, they
neglected the changes in pinion/tail rotor gearing for the ECO.  The ECO as
stock may be 140w, but you have about 22 gear options (Or something like that)
to adjust and I am sure I could duplicate the numbers the EP puts up.  All
things fair and well, the EP is great.  But IMHO, the ECO is better.  BUT,
overall, I think the new JR electric heli may really take the cake!  Good luck,

Jason
