Don't worry about it, go fly.
Yesterday, I got a torque roll out of the Four Star 40, right off take off. After the initial power burst, it could get there but not sustain the hover - hardly the best way to learn how to fly the maneuvre correctly.
I could build the same model, for a Saito 72 and spend entire flights practicing torque rolling.
Okay, maybe the entire flight less the time it takes to come around and land. You only suffer one engine cut prop-hanging low per model, on average
However, I don't like the racket at our local wet site, it's three times the drive to our e-only site and my wife likes that I don't come home smelling funny nowadays. As I am very time limited and only fly Sunday PMs, stick with what I like most makes more sense than tinkering with lots of different ideas.
