I suspect that itís not possible to hit the tail without extenuating circumstances. Iíve landed my 9a slow enough that itís stalled as it hits, Iíve then kept the nose very high to aerobrake. A tail strike has crossed my mind a few times, but I think youíd have to really work at it. Maybe with an aft CG and an abrupt pitch up below stall speed or a porpoise type event.
