I'd just write it up as a very basic NH1 to NH3 droid. I don't think it needs to be anything special especially if you consider a training remote may be used by 1st-level hero types as a training tool. It really doesn't need to be all that challenging.
This isn't fully written out but:
Tiny 4th-degree droid, NH 2
STR 7, DEX 17, INT 8, WIS 10, CHA 8
Speed 6 hovering
Equipment: Blaster Pistol on stabilized tool mount, Basic Processor
To be honest, I've never really considered Initiative to be an essential skill in SWSE. As long as there is no Surprise Round there is no flat-footed during the first round of combat until your turn comes up.
