Not to make assumptions before the report, but the Tiger is light, very low innertia, high drag, and inclined to fly out of ballance with very little provocation, could be a case of trying to turn too hard and soon for a flypast a bit out of ballance and the plane will drop speed fast and bite pretty hard.
the Tiger is easy to fly, hard to fly well and does not tollerate mishandling.
Rest in Peace.
