Mr. Beaner, THANK YOU, THANK YOU, THANK YOU !!!!!
I now have one blade painted yellow and the other blue, with the associated links painted the same! I can now clearly see the yellow blade running much higher than the blue blade. So as soon as the weather permits I need to shorten that yellow blade link and test fly.
Someone once wrote here in this forum that this whole tracking thing can be done while strapping the heli to a bench, but I find that when I do that the tracking looks fine, but when the heli lifts up and flys the tracking is off. I think holding down the heli causes the low flying blade to pull up and meet the high flying blade and hides the tracking problem. It's best checked when flying under normal flight conditions.
