Yup.You don`t have to zero after each reading, as long as you do not move the helicopter. Put the blades parallel to the tail boom, and zero the pitch gauge. put the gauge on the blade that is over the front of the helicopter and adjust the blade until you get it as close to zero as you can. Then....take the gauge off of that blade and rotate the head so the the other blade it over the nose....and put the gauge on that blade and adjust that blade to zero. Unless you have turnbuckle links, you will pretty much never get perfect zero.
