Thanks for the input. The balsa was not cut prior to assembly...in fact that side, where it broke had a leading edge
that was SOFT. Did I get a reject plane? I'll never know....but it was good in 3D mode.....just that you cannot fly it fast.
I've seen one that the entire tail came off....not only the stab but the whole thing....and one where the covering on the
wing just ripped right off.....?? I just don't know ....but like I said, I'll rebuild with solid tail feathers. Cheers!!
