Below is a link to a video on how to use the the cube.
I would suggest you follow the instructions found in Section 47 page 7 of the assembly instructions. The cube "Zero it" you are referring to is done on the RV-12's canopy deck. The beauty of this is you will be adjusting the prop angle to 71.4° based on zeroing the level to the canopy deck first ... so regardless of what angle the airplane is sitting at in the hangar or on the tarmac, the prop pitch can be accurately adjusted without the hassle of needing to level the entire airplane. You just need to level the prop by placing the level on the prop hub prior to adjusting the blade angle.
