Default Pitch adjusting links question please;

Hello, just wondeirng here, the pitch links that adjust the blade tracking, are the same links that adjust the pitch for each blade?

So if the blades are at the correct & same pitch each (o deg at all controls on the tx neutral or whatever pitch you are going for) then the tracking should be correct/on as well?

Yep. If you did a -VERY- good job in set up it should track first flight. Pat yourself on the back.

If it does not track. Mark a blade and give it a turn in or out. If that makes it worse than you turned it the wrong way.

It is the actual lift of the blade that determines the track, and if the blades were perfect this would be the pitch angle too. But the blades are far from perfect aerodynamically so in practice they will generate slightly different lift at the same pitch. Of course this is not what you want, so you will adjust the pitch to be slightly different so the blades give the same lift and thus track evenly.
I recommend setting both pitch links equally at about half their adjustment range, then roughly set the collective pitch using the servo link rod adjustments as has been described before, then first, fine tuning the collective pitch by turning both pitch links equally, and last, tracking, using individual pitch links to raise or lower the appropriate blade.
Recall that all these link sockets are one-way, they have a big side and a small side, the big side always should go on facing the ball.
