Time will tell coop, and you'd probably be ok. I'd say only one thing that held me back on some planes before.

Assumption.

Assuming that the fact that the tailplane is skewed slightly affects it's looping and rolling, it may not be enough to notice. Go through your trimming schedule objectively. I made the mistake of trimming an aircraft to alleivate what I thought was a crooked tail, (which it wasn't) and ended up making my mixes so twisted I'm suprised it didn't snap roll every 2 seconds!

remember! Be objective!
