well i believe it is not related to the flybar paddles in my case. in my perfect balanced setup the heli was rock stable even if the paddles were not the same level(i have tried).
thanks for the input.
i am wondering Marios comments on the tbe.

If the paddle blades are not at zero pitch, there will be aerodynamic forces on the paddles while turning because the outer paddle blades are effectively moving faster through the air than the inner blade.

This can put unbalanced forces on the rotor system causing the toilet bowl effect.

This effect is most noticeable on the PicooZ heli in which turning right causes the heli to go forward and turning left causes the heli to slow or hover.

The flybar on the PicooZ is at a different angle to the flybar than the standard 90 degrees which permits this heli to either go forward or hover with only 2 channels.

This effect may also be seen on co-axial helis.

The upper stabilizing rotor system is further away from the center of mass of the heli and there is a force moment when turning because of the difference in distance of the 2 rotor systems on the main shaft.

I Do Not See This with any of my 4#3's! i am flying with a little positive pitch on the flybar paddles and they make aggressive turns without any tbe. So i don't agree with what you res saying here. i am flying six 4#3's with this set up.

genco.
You may have a damaged main blade. try a new set of main blades.
it may do the trick.

i dont like the feeling of the sticks with positive pitch paddles.its like something holds the heli in the air,less responsive and less precise. i tried the positive pitch on paddles but the tbe continues, also i tried another set of main blades and its the same ccw tbe. im sick of this!

Did you bend the main shaft? are there any vibrations?

there was the vibration and the rotorhead plastic was bend,i had changed the rotorhead, this head seems to be good,also there was a lot of play on the swashplate,i changed it too. these are all after a terrible transmitter mistake crash on ground which i damaged the swashplate ball,flybar and rotorhead.it was flying like a dream before the crash and i was able to hover nose in a feet from my nose
anyway, i changed most of the parts, even the frame, but tbe still remains.

Well do the servos operate smoothly? when you crashed did it fall on it's side and hit the servo horn. you may have a damaged servo. or you may have damaged the reciever and done something to the gyro circuit inside?

woody for woodies!

well I am flying around my 4#3 v2(bl)

was showing off.....

fff along a small wall......

an inch or 2 away from the ground.....

tapped the wall......

actually chopped a blade in half!

I have crashed every variation of 4#3 1000's of time-only nicked a blade-even bl!

so these are either weaker blades than v1-or the gearing and bl are too much for them!-on a hit I mean

sigh -I guess I have to go back to being cautious flying! pout,,snivel snivel

some v2 woodies please!

I think walkera is going to phase out v1-just a hunch-but watch!

The Perfect Li-Po UpGrade For the MIA Frames

I just tested the new 1s 500mah li-po in my carbon MIA frame. Flight time seemed like forever! This is the perfect battery for these frames. It weighs 11g before the connector is soldered on. Same as Stock. It's thinner,narrower, but longer than the stock li-po. You can hardly see it up in the battery tray. I just ordered 38 of them for my website. They will be up soon! And they do fit in the stock battery cage!
cheers, johnw

John,

Those batteries look perfect as you show on your pictures. I use similar batteries on my 4#3 with the MIA Woodies, but mine are rated at 450 mah, 500 mah should be better. Nice!
