Hi All,
I am actually little bit frustrated form the original rotor head for ECO8. However I have made heavy upgrades (metall balls, bb for the padles, changed linkage etc. - http://zapa.aeroomni.com/modely/eco8/v3.jpg, http://zapa.aeroomni.com/modely/eco8/v5.jpg ) it still has some trouble at negative pitch in rolls ... I start to think about the alu upgrade of the whole head, but the alu head seems to be little bit heavy and expensive ... does it really worth money/weight ?

Is not there any other reliant way how to update the original RH for aerobatics ?

Thanks for you advice
Pavel

I have made some modification, but I did not change the ration between swash/bell-hiller input yet.

To be concrete, I have made this:
* Changed position of the beel/swash mixing for better pitch range
* Moved an axis of paddles 5mm down and add ball bearings
* Replace plastic balls by the bronze ones
* Change the length of rods to allow +8 -8 pitch

but, the mixing ration as seen on the link I have not change.
So I will think about supressing the paddle's input, but my actuall
question is mostly about the Ikarus alu head tunning - does it worth ?

thansk for the advise
Pavel

BTW: pitch up tendency in forward flight with original rotor head is terrible.
