It took me a while to come across a post that solved my problem with no lift... I had had taken off the top cap (with the big screw on the top of the rotor head) and when I put it back on I screwed it down too tightly. This meant that the fly bar couldn't move up and down like it was suppose to and volia I couldn't get enough travel of blade pitch no matter how much I turned the pitch links. Unscrew the cap, pull it up a bit, and retighten screw (but not too much). This may not be your problem but it had me stumped for too long not to mention it. Good luck.
