| There seems to be alot of confusion on how to use a pitch gauge
So in the hopes of helping others attain that perfect tracking without upsetting the pitch curve at the field I made this little tutorial.
The Pro's and cons of using a bubble level
Con's
the table has to be level
the heli also has to be level
doesn't work very easily

How to use a pitch gauge
First the setup after everything has been set 90* from the servo links to the head
Set your Radio to mid pitch
Now set your pitch gauge to 0*
Place it on the Blade and look for the space between the top of the gauge and the bottom of the flybar
the gap has to be equal across the top of the gauge
 
Notice how the flybar levels itself to be perpindicular to the mainshaft.
Now lets say you were off by 2* and you lign up the pitch gauge so it equal across the top of the gauge looking at the flybar it is clearly visible that the flybar is no longer level/perpindicular to the mainshaft
 
The same method applies to any heli whatever it'size this one is a Trex 450
The flybar ratio does not matter the 450 has a differrent ratio than
the Raven yet it works same
what matters the most is the Gap across the top of the gauge between the bottom of the flybar
once you achieve the equal gap look at your fly bar to see if it 90* to the mainshaft
you do this to both blades
No buble levels were Harmed for this tutorial
