Ok, sorry if this sounds dumb, but more than one person has made this mistake on here. Make sure your blades are on the right way. With the heli on the table facing away from you with the blades to the left and right, make sure the blade on the right has the thickest part of the blade towards the rear and the thinnest towards the front. The blade to your left should be the opposite. (Thinnest towards the rear).

Now, when you add throttle with motor disconnected, it should pull the blade grips down which pull the trailing edge of the blades down adding positive blade pitch. At zero throttle, you should have zero pitch, and at full throttle you should have about 5 degrees (a guess) of blade pitch in the normal mode (not idle up).

Before you go fly again, level the swashplate and adjust the servo push rods. As Mmatheny said, the servos should be level at zero throttle or pretty close. You can take the screw out in the servo arm and rotate it, but it should be close from the factory. Then, to set the blade pitch to zero and to level the swash, you will have to remove the rods from the swashplate ball links and either screw them up or down on the threaded rod. Its time consuming, but necessary to get it as close to level as possible. Sounds like you will have to screw most of your DOWN, some more than others. Do all this with the trims on the right stick centered.
