I have been browsing around on this site for quite a while now, since a few months ago when I first got into helis. Anyway, 100% of the time folks say to put something colorful on the blade tips to see which blade is high during tracking adjustment.

I have been using a different method you might like. Simply use a dry-erase marker. Spin the blades then SLOWLY lower the marker onto the spinning rotor at an angle pointing the same way as the blades rotate. The instant you feel contact, lift it up and stop the rotor. The high blade has a mark on it now. Adjust your links and spin again. If its still out of track visually, repeat the process. Now you will have 2 marks on the high blade or if theres a mark on the other blade you know its the new high blade.

On second thought maybe this is more complex, but anyway you dont need tape stuck to your blades, the marker wipes right off. I have used this with great success on small electrics, as well as .30 sized nitro.

Is this commonly used or did I discover something new?
