I've never added any wires and the stab has never come off on mine, or my other one, or my other one, or my other one. I wrecked them in other ways but never had that problem. I think it's a sturdy airplane but if you hit it, it will crumble. One of the absolutely most fun planes I've ever flown. I've got number 5 coming and I'm gonna over power it.
Thanks,
Barry
