The new Estes Astron II Launch Controller is fully assembled and requires one 9V battery (not included). It's brightly colored and will be easy to find in your launch box.
Unlike the original Electron Beam Controller, the new Astron II controller is safe for use with low-current igniters like the Q2G2s from Quest.
