Have my 600 to the point that I need to check tracking of the main rotor blades. Problem is that the stock blades a black CF and I am wondering what everyone is using to mark the blades to check tracking?

I would reccomend getting some bright color hobby vinyl from your lhs and just put some strips on the outer edge...Measure them so as to keep the balance of the blades, start at the bottom of the blade, trailing edge, then go over the top and around back to cover were you started...one pass and the object is to not have any seems the will peel open when your rotor blades are spinning...If that makes no sense at all give me a call and ill try to explain it a lil better...lol Jeff 623-628-5902

Thanks for the quick reply Jeff. We don't have much of a LHS here, it's more of a craft store that caters more to the quilting and painting crowd. I do have some colored electrical tape that is not to thick so will give that a try. The blades on my 450 sport are white so I just used a read and blue sharpie to mark them and it worked great without adding any weight to unbalance the blades.

Theres another way to track the blades. What you want to do is to unplug the motor and bring the throttle up half way so that the the pitch would fifty percent, or zero pitch. After that, what you want to do is to hold the flybar parallel to the body of the helicopter and then take a pitch guage and make sure that both blades are zero pitch. If they are, your blades are tracked and you are ready to fly No more of that tape stuff.

If they are, your blades are tracked and you are ready to fly No more of that tape stuff. In my limited experience that gets you close, but not perfect. When you pull it into a hover you could have a slight difference in tracking. If you see that select a blade (doesn't matter which one, but note the one you change) and screw the link in or out a half turn (again, doesn't matter just remember what you did). Put the heli back in a hover and if the blades are perfect - you're done. If the blades are better go 1/2 turn more on the same blade. If the blades are worse, go a full turn in the opposite direction on the same blade (1/2 turn to put it back, then another 1/2 turn to fix the original problem). Using a pitch gauge as the original poster mentioned, I've never had to go more than 1/2 turn to get near perfect tracking.

I am pretty new at this as well but would agree with you. The resolution of my pitch gage combined with aging eyes leaves some question as to accuracy but your right it would get close. I have noticed on my 450 sport when I change blades I need to re-track in a hover because nothing has changed with the links and the pitch reads the same but in the air the new set does not track the same. I think there are other forces at work that cant be seen with just a pitch gage on the bench.

You can also do it by means of somehow strapping the heli down to something where it will not move or lift on you. I've seen home made stands where the heli's skids are strapped down to check for tracking. This may be a bit easier to look at the spining blades without hovering.

I got the yellow blades cliff has for $36.99 since they were cheap and I would not want to hang myself when something bad happened. However, the coloring was hideous. So, I went to lowes and got a rattle can of neon yellow and neon pink krylon and, after sanding the smooth surface a bit, applying a coat of matte white Krylon, I painted the blades with one color fading into the other with one blade yellow to pink root to tip and the other way around. REALLY makes tracking easy! See Pic. Attachments:
