I have seen alot of posts about this yo-yo type movement in the CP Pro now. I am starting to think that there may be a little more to it than the "Sticky Collective".

My CP Pro right out of the box has these up-downs, which I have never experienced with my regular CP. I have torn my head apart, checked bearings and such, put silicon lube on the spindle and o-rings and still have the up-downs.

Well, I braced the little heli so it would not take off under 3/4 to full throttle. I can clearly see the blades rocking towards the ground at the front of the heli and towards the tail boom at the back, as the rotors are making revolutions. I think this is exactly why I have the up-downs.

I have not crashed the heli at all, so this makes me think the head is slightly defective. Could be a bad batch of them from the plant???? There seems to be a lot of play in the head, when I push down on the blades. The only thing I can compare it to right now, is my TREX's head. This is not really a fair comparison.
