I am a complete newbie to helis i just bought and built a nexus 30, but i have a question. Are the flybars and paddles supposed to move when you push down on them? or are they supposed to be locked in a straight position?

ya can fly with a locked flybar, not well, but it can be done.
the flybar IS suposed to be able to freely teeter. this sort of dampens control inputs and gives a small amount of gyroscopic effect to stabilise the heli.

to answer your question, the asnswer is yes it's suppose to move once you build up head spead it all levels out. very easy heli to learne to fly.
