WC. Not trying to be rude or anything, but if you are unsure of how to track blades. Do you think you should really be trusted to set up someone else's helicopter? Especially charging them to do so??

Don't you talk about it in your beginner help videos?

Never work on both blades, always work on the same blade, if you choose to work on the blue one only work on that one.

Adjust the one on the left.

i don't even mark the blades just the grip. Then work on only the one blade. Turn the ball link one way if it gets worse turn it back the other way til it's right.

Good Luck

I usually bring the higher blade down.

that's good but putting the pitch gauge back on the blade to see which one was not zero at med stick i think is the best method
that way my pitch at mid stick stays almost perfect.

if i try to follow another blade to track them together i could lose some degree of pitch.

Adjust the blade that isn't zero degree's at mid stick.If you guess and pick the lower or higher blade,you take a chance of having uneven high/low pitch range.

It's best to get it right the first time!! Haha! I haven't had to adjust tracking at field in a long time. Once you have a good method of setting it on the bench and use good blades, it is not a problem.

The problem with checking the pitch is that not every blade is made exactly the same so they flex a little different making the blades out of track. My blades are always at zero pitch with mid stick in all positions. I turn the heli while holding blades and watching the pitch gauge. With really good carbon blades this is usually all I have to do but sometimes i have to track one. Usually only one turn.

REALLY?
I have been in this for less than 3 months and can already tell bad tracking by sound. You should teach a correct setup by sound.
If you can't remember which linkage you adjusted put a sticker on it!

By sound HMMMM nice .

so you just adjust them until they sound good ?

after i tracked them with the gauge it was done deal no need to hover listen land adjust hover listen land adjust .

sound method sounds like a pain but if it works for you congrats

also when you are tracking by sound how do you know which blade has the bad pitch problem ?

One of each; blade, grip, blade grip link-rod and upper swash ball as well as one side of the main rotor hub are marked and easily distinguishable from the other side. This is the side that I use as a reference when making adjustments and the one that I spend the most effort getting zeroed out at midstick during setup. All adjustments are made to the other side after initial setup unless the adjustment is to correct an error made during setup.

This ensures that I can disassemble everything, reassemble it and have it track accurately when done with the minimum amount of guess work. I've recently taken to doing the same thing with the tail. Thirty seconds with a sharpie. Might be unecessary but it's easy and it works for me.

When you set the throttle to 50% and checked the pitch....why was one of the blades not 0° to start with?

You don't need to fly it or tape the blades up to check that.
If one blade is not the same pitch as the other during set up...it's wrong.Fix it before you fly it.

It's a very very very rare thing if my tracking is off on the maiden.
Take a few seconds to get it right BEFORE you stick tape all over it in a premature hover.

Once the blades are both 0 degrees at 50% throttle,check them at 100%.
If they are different there,fix it with travel adjust.Don't mess with linkages because they will be different at 50% if you do.

Now check them at 0% and make them the same with travel adjust again.

Now use the swash mix to get the amount of total collective pitch you want.

If you have more positive pitch than negative,your swash is too low.
Start over.lol...

I literally never use the word literally right.

New head or not...set the head up right before you try to fly it.

There's no logical excuse for the blades having different pitch anywhere throughout the full range of motion before you spool it up.

i did set it up before i spooled up i set booth blades to zero but one was out of track.

so i was not sure if i should track them bye eye or zero both blades with the pitch gauge.

pitch gauge worked the best like i said up above

go up and read
