RE: new heli!!!!
Generally a good setup has all control links at 90* to servos at center, and to any other levers that apply.
As long as you can get around 10* to -10* of pitch mechanically the heli should be able to do very much. I just set my newbie heli to do that (and didn't follow my instructions for beginner setup) and limited pitch via the controller from 10* to -3*. Later all i have to do is turn off the limits on the control and i'll have a great setup.
Everything should be balanced, all links in pairs the same length... etc.
