New to CP - Need advice on setting up Eco 8

Post by Malcol » Tue, 06 Nov 2001 04:18:18



Hi all,

I've been flying Piccolo's for nine months and can hover it quite stable for
a complete pack.  However the local hall tends to get booked up too quick;y
so I wanted something that I could fly outside in the garden or park.  After
a lot of thought I went out and got an Eco 8.

Whilst the instructions are quite good (compared to some of the things I
have had to build) there is nothing on setting the heli up for flying with
regards to blade pitch etc.  I have built the kit with all rod lengths as
per the instructions, and set the distance between the swashplate and top
bearing to 17mm with all servo's arms in the horizontal position.

With all the links set, flybar level and horizontal should the blades also
be level (mine currently have positive pitch (no idea how much as I have no
gauge).  Can anyone provide further information in basic terms (I'm new to
the terminology so please don't baffle me with revo mix, etc) on the static
setting up on my new heli.  I can be e-mailed at mcrabbe(at)lineone(dot)net

Thanks

Malcolm

I'm not in a position to get at my ECO or the documentation at the
moment but ISTR that mine ended up as you describe it.  I don't recall
having to do any great amounts of frigging 'round from the initial build
to get it set up correctly, just a tiny bit of fine-tuning of pitch
curves.  I'd strongly suggest you invest in a pitch gauge tho, it makes
it shirtloads easier to set up exactly as you need with no guessing.
Unless you're intending to use a 'V' curve and hover at 3/4 stick then
having +ve pitch at 1/2 stick is correct- 5-6 degrees and 80 % throttle
would be a good starting point

Depending on what motor/ battery/ ESC combination you're using you may
find the easiest way to find a starting point from the initial build
without a pitch gauge is to set the pitch curve to default
0-25-50-75-100% and throttle to something like 0-50-100-100-100% for 5
point curves, then you can fine-tune pitch and throttle once you've got
it in the air.  Be careful with the go-up stick tho if you do it this
way.

Many thanks for the advice.  I'll add the pitch gauge to my shopping list :)

The positive pitch you describe on the blades is correct.
For learning with the eco you should set up you pitch curve as follows

Stick  position 1      2      3      4      5

               20%    45%    50%    55%    75%

This will give 0 to 1 degree positive pitch at low stick - a couple of
degrees above hover (so you don't get into too much trouble) at high
stick - and a nice soft feel around the hover. You can get away
without a pitch gauge for now if you set up this way. Good luck with
the eco it's a nice machine (and easier to fly than your picollo)
