I watched the pictures over and over again, but still I see not so clear how to open te Crystal chamber.
-Is it open all the time?
-Do you unscrew the black ring and turn the inner black part a 90 degrees from the outer metal part?
-Or do you take off a peace of metal?
This is not ment disrespectfull, but I dont know all the parts names that well and also my English is not so good.
PS. I also found a YouTube Video of a TPM Negotiator with a CF board here somewhere.
It sound twice as load as the Maul.
I think it's compareble with my Anakin ROTS.
