What Kiwi4 said is exactly the first things I was going to also say to you. For one, the main gears are hardly ever "true" and perfect but still won't cause the wobble your describing, especially once the rpm's get up to speed. I don't have a CPP2, but I have two of the original CP Pro's and learned with the first one 2 years ago. So it sounds like you crashed it, and then got the wobble ? Or did the wobble just start occuring ?

The plastic rotor head is a weak part also, and after a crash or two will get some slop or tweaked and will usually need to be replaced. For one, when you crash and that little tiny retaining pin going into the plastic housing will usually ream out that hole in the rotor head making for some nice slop and eventually getting things loose which causes wobble. I've been through many of those ! To help save the rotor heads, most use a softer paper clip cut to size to use instead of that stronger retaining pin so that when a crash happens that softer paper clip pin will then break ASAP and save usually your main gear from stripping, and save your rotor head. So just a thought.

Also I've had some serious wobbles before, and I've gone mad before trying to find the cause with lots of new parts and swapping them out one at a time. Well guess what ? All it came down to before was unbalanced blades... So if you did crash it, and are now using different blades, that will definately cause some wobble if there unbalanced for sure. And yes, if your spindle is even bent a little you'll also get that wobble along with even a bent flybar or the flybar not perfectly centered, or even the flybar paddles not perfectly spaced.

But I would definately check that plastic rotor head. With the faster headspeeds that the newer CPP2's have, I bet its that possibly... Just with the slower headspeeds of the CP-Pro's, those things were a weak-link as far as getting loose and sloopy and bent from a mishap.

Its also a good idea to have a very, very tiny gap where your retaining collar is resting with that lip on the bearing... Say a paper thickness, or even 1mm... To tight, even resting just on the bearing will cause some drag even though its just resting on the inner race of the bearing. We also do this with our bigger birds...

You didn't take your spindle out before did you, and forget to put one of the washers in, or put them in the wrong order did you... ? Anyway, a video would possibly help if need be...
