Twitchy tail

Hi there,

Im new to this forum, but have been participating on the Piccolo forum for some time.

I purchased a Eco8 Original version with the two stage gear box.

I find the tail very nervous and not eaily controlable. Does anyone have experience with this older verion and how to get the tail under control...

Thanks guys.

P.s. does anyone know if I can put the alu upgrade part for the tail as solod on the Ikarus site onto the older heli..
