I found the pitch gauge hard to use and inaccurate. Now I just like to measure the distance between the folded-back blades when the heli lies on its side on the edge of the table (blades hanging down). Just do the math: Pitch = Sinus (gap / blade-length) , then divide by 2 and you get the pitch of one blade.

Or use the pitch tool in this program:
