I don’t think the head would fit a R1 though...

Wait, I don’t think it would work on all R-series droid though... *cough cough* R1 *cough cough*

Can I add this to Wookipedia? (For some reason no one has done that yet)

Although ya, the neck looks like a weak point, perhaps like the magna guards that General Grievous used, or even the battle-droids, he might be able to function without it...

This explains so much! (BTW I’ve always like the R7 through 9 best)

I love these pages on Astromech droids! (Although I still think BB-8 totally stole R2's thunder)
