It appears that the crash occurred almost immediately after takeoff. Probably still climbing out and hadn't yet flown to the airspace where he would have been performing the aerobatic maneuvers. Whatever went wrong seemed to happen within moments of breaking ground and ended just south of the airport property.
I know of an incident where a pilot set him fuel selector handle to chose the fuel tank noted on the preflight check list. However he only thought he had fully rotated the valve handle but was actually not drawing fuel from either tank. There was only enough fuel in the line for a takeoff and climb out to about 75 feet when his engine quit due to fuel starvation. The pilot was too low to do anything but make a controlled glide into the trees ahead. He survived with minor injuries, but his airplane was totalled.
There is absolutely no reason to believe this pilot was attempting any aerobatics at that point in his flight.
