The stick control system is a lot more fiddlier than your traditional control column and it was sometimes difficult to get back to earth without a rather large bump.
There was an issue with the elevator bearing which could require up to 2 pounds of stick force to move it. As the control forces continually varied, anyone trying to fly it by feel rather than attitude, came down with a bump! Plus the finger brakes and slender undercarriage. I test flew one with the Liberty rep and concluded it was not as forgiving as a 152.
