I have heard some experienced pilots say it's unpleasant to fly
Here's a clue to the handling, Genghis.
Despite a differential aileron system that actually reverses the movement of the downgoing aileron as the upgoing one passes about half deflection, it can hold a hold a steady heading sideslip without any rudder at all.
This, together with ailerons on only one wing means the rate of roll can be measured in RPM!
Like many difficult things though, the effort you have to make to compensate for the deficiencies brings it's own reward in a sense of achievement, and you become quite sympathetic to them.
A bit like the 'Stockholm Syndrome' !
