Darticus,

As Wnuk suggested go to bladecprepair.com and research everything... Mechanical set up of a heli, is imperitive, so critical..
Just being a bad guy here,,, you can't think its set up correctly, you have to know that it's set up correctly...

You have to go through all the mechanics of the heli, check blade pitch, blade tracking and most inportantly that the swashplate is level. Make sure that the rotor head is not binding.. It's a big learning curve, just go slow and take your time to understand how the heli works and why... Makes it much easier in the long run... Once, off the ground, with all the trim levers at center position, it should hover with very little corrections, if to much correction is required, some can be corrected with trim inputs. However, if at anytime you have to move a trim to the max. up,down,left or right... Time to level the swashplate...
