I have put tons of flights on mine with a Saito 50 4 stroke.
It will do almost anything with that motor surprisingly.
The Sukhoi will do just about any trick in the book.
I have done some very, very violent maneuvers with this aircraft and it did not stress any part.

It does get touchy at lower speeds though. It's good to keep up the power on aproach and chop the throttle over the runway threshold. It slows down quickly.
