I have several dozen flights on mine with an original 19lb thrust Rabbit, nice flying plane with no bad habbits. Only issues I've had have been with the poor quality of the cheap Chinese plywood that's used for the LG mounts. I had a rough landing a few weeks ago at Mississippi Afterburner that should have hurt my pride and nothing else, but the nose gear former came apart. Not a difficult fix, but something I shouldn't have to do. Two layers of 1/8" lite ply is no substitute for real 1/4" aircraft ply.
