I'm getting the Strike Freedom Flash soon, and I am gonna need a little external expertise. The kit has two circuits in it, one that is the body and extremities, and one solely for the head. The main circuit is powered by three batteries. (AA or AAA I'm not sure.) The head simply has one button battery in it, a la PG RX-78. Anyhow, I want to tie the head into the main circuit, much the way it was done on the PG Mk-II. Does anyone know if I need a resistor or something for that?
