Please try to ask more than one question per thread, so far you seem to have started a seperate thread every time you've had a different question, its a bit unneccessary, especially given theyve all been setup related.

But, in reference to setup, since it seems googling has not provided your answers, you will definitely need in-person assistance.

I set up my first heli, a 500 size, with nothing but a lot of googling and some reading.

This forum has a search function that can answer most of your questions, and those it cant, will be because every heli is slightly different, hence, if you can't work it out, get some face-to-face help.

It is something you just need to learn and figure out. copying someone else set up doesn't ensure it will even fly.

There is a whole set of complications that depends on what servo is on what side, what servo you are using, radio, gyro, tail servo, and a 3D pilot is going to have it tunned differently that someone just starting out.

You need to know how everything works so you can trouble shoot and repair it when it crashes.

You also probably want to start with a linar pitch and throttle curve. Your end points will be depended on the servo, which hole on the arm, and how much pitch you have in the swash setting, use a pitch guage and you should see about -4.5 - -5 at low stick 4 or 5 at mid and 9-10 degrees at high.

I'm going to have to stop you there. having 0 degrees at something other than mid-stick teaches bad habits, 0 degrees pitch should ALWAYS be at mid stick to teach correct muscle memory.

FWIW, my pitch curves on my 500 are (and I'm a learner)

Code:
       Stick Position:
        -100%   0%   100%
NOR:    -.5*   -.5*  -.5*
IDL1:   -2*     0*    11*
IDL2:   -11*    0*    11*
Throttle curves (DO NOT COPY THESE):

Code:
        Stick Position:
        -100%   0%   100%
NOR:    0%     85%   100%
IDL1:   0%     85%   100%
IDL2:   100%   85%   100%

the '120' and '140' I am assuming are the CCPM settings, which as phoenixheli says, MUST match the swashplate setup, or you will have serious issues later on.
