Can anyone answer me this? On one of the toy versions of the Y-wing, the included astromech co-pilot is a yellow R5. I've also seen R5s depicted as Y-wing co-pilots elsewhere. Subsequently, I have a question. If anyone has read the new essential guide to droids, it describes the R5 series astromechs as being terrible droids, especially for piloting.
So my question is, why would the rebellion use R5 astromechs as co-pilots? Simply a lack of funds to use better droids? Or something else? Or am I over-analyzing something trivial? Help me out, guys!
