After the latest crash on the CP I can't seem to get the blades to track properly. I've swapped most all pcs but I noticed when changing the pitch by hand(with the head removed) it feels like the shaft between the 2 main rotors is bent? I can't seem to et the screws to loosen up to even find out, gonna have to get a 2nd allan wrench I guess to hold the other end from spinning, or is there an easy way to get this ou and check if it's bent?

Thanks.
