this was one of the two astromech droids used by Darrus Jeht aboard his Delta-6 fighter, during the height of the Clone Wars. The Delta-6 was one of several prototypes that remained in active use after the production of the Delta-7, and Jeht chose to leace the two-astromech set-up intact. However, R4-D1 and its companion, R4-D2, often provided more input data than the ship's flight computer could handle, causing certain instabilities to occur at the worst of times. The droids also tended to argue with each other over their input, causing another set of problems. Jeht, however, liked the unpredictability of the craft, and kept it at the Almas Academy along with the Night Gyre.
