Probable cause

The pilot's failure to maintain an airspeed above stall speed. Factors include his improper decision to takeoff with a tailwind, and the effects of the tailwind upon the aircraft's takeoff performance.

Sequence of events

Analysis

The pilot took off with a tailwind of about five knots, and just after liftoff, the aircraft drifted off to the left of the runway heading. During his attempt to realign the aircraft with the runway heading, the pilot inadvertently allowed the airspeed to become too slow, and the aircraft mushed/stalled into the terrain about 200 yards off the departure end of the runway.
