Davy,
perhaps it's my style of flying but I have had no problem with the tail on my HR3 (even before reinforcing the tail) With the FA-80GK in it's certainly no slouch either, although I don't point it flat out at the ground to see just how fast it will go. I prefer to fly in a much more scale manner including high G turns and have pulled turns so hard the plane has flicked out of the turn yet not broken anything.
