Thraxx and Arten.
Arten's new head after his old one was blown off by a vulture droid. Thraxx was so close to Arten that he got him a new head even though it would have been cheaper to get a new droid.
ya, Thraxx made the name 'arten' after the number of buzz droids the droid had killed.
QZ is the initials of his best friend Qual Zoha who died in battle. The droids official name is R3-P7 but Thraxx didn't like 'arthree'
I f you know your astro droids, then you would know that "R10-QZ" is incorrect. The company that made the droids, Industrial Automaton, never made an R10 series, and by the looks of it, this would be an R2 or R3 series droid. In fact, they only made a P2, Q7, Q9, and R1 through R9 series. Look it up on Wokieepedia.com. And the "Z" should be a number. Beside that little fact of trivia I bet you didn't know, good job on the fighter. I might build one soon.
