ok to track your blades you need to

then

its better if some 1 els can help you
as you need to get in a good hover at about 5ft high
and look for the red tape
you will be able to see if the red taped blade is higher or lower than the other blade
if its higher then shorten the link in the pick to lower the pitch on that blade
if its lower then make the link longer to give more pitch on that blade
just a turn at a time then try hovering again
untill you can see the blade is in the center tracking with the other blade
then thats it your done

ooh my god ,, i spent all the shopping money on helis DOH!!

My last tracking issue happened with a set of blades that did not require any balance or CG correction so there was no tape on it. To be able to find out which blade to adjust I painted the leading edge of one blane close to the tip with a permanent ink pen (not really permanent since I cleaned with alcohol later)

My 2 cents

No tape needed. I scratch an X in one blade grip. I make an adjustment. If tracking is worse, I reverse the adjustment (with interest). The X tells me the blade I adjusted. My tracking is perfect.

Same what Wisdom-Seeker does, I just put a small line, or scratch on one blade grip.

Usually I paint both tips (like 1 orange and the other yellow) so they stand out real well and I can see which blade is higher/lower.

But I haven't gotten around to coloring my current set and am pretty good at eyeballing it. If it's out of track, I land and switch on throttle hold, move my collective stick to 50%, sight each blade to the flybar to determine which one is most neutral and adjust the other one the direction it needs to go to also be neutral and it usually works.

Granted a lot of blade sets/machines track different under a load. That's what makes the colored tips the best and easiest method. You can see where each blade is tracking synonymously with seeing that they are not tracking the same. No guessing, and quick.

I fly woodies, so invariably one blade has some tape on the tip for balance,
However, if you object to have your new carbons all messed up with tape, do as orhers do.
Mark one grip, adjust the long link (Raptor, don't know the others), see which way the tracking went, adjust the other way, etc, etc.

After that, you may want to look at your pitch curves again.

when you have done take the tape off
it doesnt mess it up and if it does then just wipe it off

Hehe, with the sceadu blade tracking is easy with a decent set of blades (eg your new carbon ones) all you do is set the pushrods to the same length and fly

I know its not an answer, just expressing how I was pleased to find it so easy, that it tracked perfectly out of the box, you'll find that with most helis from Hirobo, if you have a decent set of blades and you set the rods to the same length, then probably 98% of the time it will track right away.

Adjust one blade and mark with pencil so you know which one it was. If tracking is worse, then adjust the other way. When nearly correct, I use bell-hiller links to fine tune. I don't like using tape as it upsets the balance. Before I do any active tracking, I allways check the static tracking. Then when doing active tracking, I can be pretty sure, tracking will be maintained in inverted.
