It didn't break up, it folded a stab, John. I'd almost expect that when you almost double the recommended engine size AND do full throttle snaps. Since putting flying wires on the new one it hasn't burped at all. Again, I'm sure you know who I am at this point and know you've seen how I fly. Structural failures have been my only cause for any crashes since getting off my trainer. To put it into perspective, I've put in an old Seagull Plasma P-51 .40 size with a .91 2-stroke on it, Horizontal stab failure. Modeltech Sukhoi SU-29 with an O.S. 50 SX diving snaps, broken stab,saved, strengthened and still flying. Modeltech Extra 300 had the 50 SX in it,diving full throttle pulled into a snap, stab failure into oblivion. And finally yes my last Giles did go in after getting it flying just how I liked, able to do PERFECTLY flat spins, but when you add some throttle with a Saito 150, a 16X8 prop, a 5 cell pack and Digital servos that will convince the flight control surfaces where they need to go, ANYTHING can happen. New one WITH the flying wires has held up in same instances.
