Not to bash anyones flying abilities but it is very possible to do a very nice slow roll with the Kingcat the length of the airfield in a perfectly horizontal line from end to end. I am not the best pilot but I know this can be done because I have been practicing slow rolls with the Kingcat for some time and have become very accomplished at slow rolls. I think it one of the best looking maneuvers available to us as model pilots. As for proverse roll, I have not experienced this either.

The non-axial rolls are likely due more to lack of being use to the particular plane or just not enough practice doing slow rolls. It could be improperly trimmed or any other number of things that have nothing to do with the flight characteristics of the plane itself.

The only issue with knife edge that I noticed is that you must do it at higher speeds but I think this is only because the plane is very heavy and just does not have the power to maintain knife edge at slower speeds.
