I just reread your original post.
10 degrees up elevator trim...is that right?!?!?
Something is terribly wrong.
Do you have an incidence meter.
I recommend you get ahold of one and try to figure out what's going on.
If you are in fact in the middle of the recommended CG range there is no way CG is causing 10 degrees up elevator trim.
That is as much TOTAL throw I am flying with a pattern plane I am just starting to trim.
Time to check, recheck and think about what the crash caused.
Good Luck.
