mmmm power is the typical EDF high perf setup of 12s 5000 Lipos. Full throttle time is ..not much. Overall 3 to 5min with throttle management. 30 sec max at full. Therein is the problem for full size. Full throttle for anything more than 30 seconds will kill those batts. I think this was a Shuebeler fan which is nice fan though.
