She is a good sport flying airplane with a Common Sense RC motor upgrade. I am not a 3D pilot, so I could not tell you how well she can 3D. I find it is very stable and handles very well with the E5-L-13 I put in it. Set up is tricky. It would take an experienced RC pilot to get it to 3D. The gear is weak too. Other than the stock motor and gear, everything else is rock solid. I just purchased some carbon fiber gear, I will let you know how that works out. All in all, stable, fast and responsive with my set up. Oh, and using a 10x6E prop with a 30 amp esc. What would you need to know for 3D?
