I have been working on my axe, replaced main head, Rotor blades, and quite a few of the other little plastic parts. I replaced them because of a minor blade strike but replaced other parts any way just in case of hairline cracks. My question is about traacking the blades. How close do they need to be? It seems that I turn the linkage half a turn on the high blade, then the other blade becomes high. I check it by holding the heli then increasing the throttle stick to look at the blades, I have a black tape strip on one of them. Maybe instead of increasing throttle I should check by using throttle up switch and center stick? Any idea's?

My tracking experience with the AXE leads me to believe that some tracking issues are unavoidable. There isn’t enough resolution with just the two link arms so you can’t get any closer than a half turn. The greatest problem will be vibration so keep an eye on your screws and you should be fine if you’re a little out of whack on the tracking.
Having said that, you might look at your blade balance. The wood blades can come with one heavier than the other so use a simple blade balancing tool to see which is heavier. Apply tracking tape to the lighter one until they’re both in balance and the same weight.

I’m not sure how much of the head you’ve replaced but the feathering spindle might also be causing some tracking issues. If it’s bent, even slightly, you’ll have a harder time tracking.
The best and safest way to check your blade tracking is to hover a safe distance from you and have a friend check the blades. Land and make adjustments as needed.
