Hi, Im totally new and actually this is my first post...Im trying to build a sandtrooper backpack but continue to run into what seems to be the same problem for everyone. Where can i buy the radio?!? Ive used some makeshift parts to put a temp in place, but Im trying to be 100% on this thing prior to attempting to join the MEPD. Ive checked the boards and followed links but ran into dead ends everytime. any help would be really appreciated.
