Lilpilot13,
Most likly the main shaft is bent. Remove the blades and power your BCPP on, and see if it still wobbles. If it not wobbling, open the book your bcpp came with and look up about tracking and how to set it up.

XTMer,

Look into buying a used one here on RC Universe. There are always blade CP and CPP for sale and you could get a really good deal. The blade Cp is a little easyer to fly in my openion and is easy to upgrade the head to the CP pro. Lots of good prices on upgrades also.
