Wingracer,
I have the X20. The blocks are marked with the motor timing, not dots, but I assume the ammount of sensor rotation would be the same.
What I am trying to figure out is if a flip the 27.5 and install it upside down what timing does it give me.
I read somewhere about flipping the inserts, but I can't find it now.
I am presently running 70deg advance with my killshot and wanted to know which insert would get me close to the same.
I am just trying a couple different motors out of curiosity.
