Stange, we fly our Reflections and Turmoils pretty hard when outdoors, doing multiple snap rolls over and over, blenders from two hundred feet, waterfalls under full power and we have not had a single inflight failure yet. The Turmoil is slightly weak horizintally, we cured that by running three or four strands of dental floss along the horizontal fusalage pieces, held in place with thin CA. Haven't cracked a horizontal fus piece since, except for some really hard crashs, and then nothing that wasn't repairablt with a little CA. I still have my first Turmoil that was built over six months ago, it has been flow a lot and is getting a little doggy looking, but it is still flyable. So far the only trouble we have had with the Reflections it that they won't stand a verticle crash onto concrete. I'm still looking for the plane that will do that.
