Is that SU-31 good at 3d?
Depends on your engine selection and flying ability.
It's not a lightweight model by any stretch. Plus the large hunk of lead they hide away in the nose to balance the too-heavy wood used aft (and lack of lighter construction back there) don't help either. And the ailerons aren't what you'd need to do 3D effectively.
