Hey dudes, as an addendum, I went checking my heli out with a profi dude (David Dutrieux, belgian 6fold champion 3d etc, he's got a heli shop and I took some lessons from him) I turned out that my gyro didnt work at all. Now I bought a new gyro http://updaterc.com/catalog/gyro&servo.htm the gy 240 Heading hold. works great and makes the tail rock steady even in wind !!
