LUCKYYYY! Looks like a low wing aerobatic trainer... Good second plane. I would not expect any hot knife edge action out of it unless you master the stunning manouver known as the "falling knife edge" This is where you put the plane into a knife edge and as it is lossing altitude you simply roll out of it as low as you dare. Far more spectacular in a plane that can hold a knife edge where you do the same thing but instead of rolling out you power out maintaining the knife edge neutralizing the decent mere feet off the runway.
