Eco 8 Assembly

[Ole]

I am a new Eco 8 owner and new to helicopter flight with the exception of the Piccolo and computer flight simulator. I am in the process of building the Eco 8 and have run into several questions, that I hope someone can answer for me.

1. What pitch range should I set for this heli (10 - 0 ) ? 6 degrees hoover.

2. Many ball links seem tight when assemblied and does not seem to allow for very free movement, is this normal ? Is lubrication recommended ?

3. There seems to be a lot of interference with my pitch compensator and does not allow free movement on the collective control.

4. What tuning parts would be recommended besides the swash plate ?

I've bee reading the bulletin board for a couple of days and have found much useful information.

Thanks for any advise.

Follow ikarus recommandation and try to get:
low: -3°
hover: 6°
High: 10°

Mine got this problem too. I solve the problem using one or more tips given on the Ikarus BBS or on personnal websites.
- put a ball on a piece of wire and put it on a dremel or else (I use a driller machine) clip every link on the ball and give a run at high speed to polish the inside of the link. This helps a little.
- run your mechanics without the blades during one pack. Play with your commands while running (Secure your heli when doing this to avoid damage) This will smooth a lot the links.
- go to your dealer and get a plastic on plastic oil bottle (the one from Robbe seems just fine) and let a drop on each ball.
-some persons have modified their link to be able to adjust the ball link pressure with a little screw but i dont like this tuning a lot.(source for failure if screw unscrews)


>3. There seems to be a lot of interference >with my pitch compensator and does not >allow free movement on the collective >control.

In the upper part of the movement the pitch compensator touches another link. Some persons recommend to mount the pitch compensator upside/down. I have tried but got the same problem (it seems that this tips only work with the alu levers) My shop keeper (who's a great heli flyer) fix it by bending the link (was too simple for me,or i dont dare to do it). Nevertheless the heli flies good with the interfeering link bended. So do what you think is good.

-The Free-Wheel is a must have. The electric motor give too much stress on the wheels when suddenly reducing the throttle. The pinion gear does not like it a lot. I buy the free-wheel at same time as the heli. I'm pretty happy to have done so. After landing you dont have any blade problem because the rotor mast is under motor break resistance.
The free wheel allows the rotor to slow down at its own pace. Dont try to fly without.
-The tail boom support is also a great thing to streighten the boom and to lower the effect of vibrations on tail rotor response.

Hope this will helps you.

Thanks Marbaise
I have ordered the autorotation gear. I Mounted my pitch compensator upside down and in my case it gave the clearance it needed. I am working on your other ideas. By the way do you use a Futaba 8uhps? If so what are your setting besides Heli SWH4.

Hello again,

I'm currently using a Futaba FC-18.
I'm using the 90° swashplate 4 servo program.

Actually, the heli is set up to fly without any supplementary mixing possibility.

I just have to invert the course of the tail rotor servo and the throttle. (Full speed when stick down ... definitively not a good idea...)

My firstname is Philippe, you can call me so...
