Are all carbon blades balanced when you get them?

No. Some are, some are not. It seems the expensive nice ones ie. Rotortech, Radix, Edge, Mavrikk pro, etc are balanced. I have run into some of the cheaper ones that were not though.

just make sure you always check balance with a new pair of blades.

yeah but how much of the time is a pitch guage acurate? sure, the devices that match each pc rod are great for getting things close and work well but it is such a pain when you get to the field and the tracking is slightly off and you have to guess which one to adjust because you cant tell em' apart. the tape makes it easy to do in a jiff if needed. if you dont like tape on your tips, the hjust peel em off afterwards

i will admit to using tape at the field when i can't tell with a pitch gauge but that is only ever on clone heli's hk450 and 500gt(i never have issues with pitch gauge tracking on my real align's)

well i gotta admit my view is fuelled by 22yrs of helis and the precision, technology and designs have come a long way but its tough to get an old dog to change his old ways
i always put even the top brands of carbon blades on the balancer when i take em out of the package just to make sure and 99.9999% of the times, they are dead on. my fear is getting to the field and finding that the few ounces that one is off is going to cause shaking and a windy field is no place to balance blades so i play it safe

...even if the blades are balanced, it doesn't mean that the tracking is on.

What I do is check the balance - any tape added I use as tracking tape (doesn't need to be much!). Set one blade up as the reference blade and mark that blade grip as the "reference" side of the rotor hub too in case I take both blades off for whatever reason. I then set that reference blade up on the pitch gauge. Then it's off out to the field to spool up and dial in the other blade with tracking. NOTE:- last time I replaced the JP carbons on my Rappy 30, I only had to check balance - the tracking was still spot on.

Tach.

I have never had a set of carbon blades that were unbalanced. Maybe I am just one of the lucky ones.

I bought a blade balancer because of threads like this just to satisfy my own curiosity. So far all the high end blades are close, but not perfect. The cheaper ones definitely need to be checked. I haven't found a set yet that was close.
