yeah, it sounds to me like basically you're not adjusting the right part. You've gota figure out which blade is off pitch first. To do that unplug the motors from the 3 in 1 and arm the heli. btw these instuctions are for the pro since that's what it sounds like you have. 2 options leave it at 0 throttle in normal mode. The pitch should be -1, whichever blade is not that, that's the one you want to adjust. or you can do it at mid stick and trim and idle up and the pitch should be 0.

After you figure that out, the links you are going to want to adjust are the ones that are attached to the mixer arm that screws on. They are short links that have a metal screw type thing inside of them. You can either shorten them or lengthen them. If you shorten it will give you more negative pitch on the blade you are working on, and if you lengthen them it will give you more positive pitch. Just remember to test the tracking around hovering throttle, or 50 to 75% because that is where the tracking matters.

Hopefully that advice, plus the advice that has been given by arrow and whirely will help you out =)
