If you react pretty quickly. Practiced it multiple times in an MD-500.
Not sure what the HV diagram is like for an A-Star but if the curve starts at 1,000 ft or less then you definitely can.
Test pilots who design the charts are supposed to cut the throttle, wait a second, then react to land the aircraft and if they can do it safely then it's logged on the chart. Naval Test Pilot school goes out and does that procedure live in a JetRanger every class.
Now granted, I'd guess with an A-Star they wouldn't be able to "wait" very long.
