The dihedral wing on most trainers and the small rudder throw make KE a nearly impossible maneuver on trainers. Yes there are those that can do it.
If you're to the point where you're trying to learn knife edge flight, its time for a second plane.

Exactly!
The high wing dihedral causes the plane to roll while at the same time it pulls opposite the belly. Right thrust also tends to make the plane behave differently depending upon which direction you are attempting to knife edge.
Couple this with trying to fly the plane in a knife edge and you have a disaster waiting to happen.
It CAN be done with enough power, but it is certainly much harder than on most aerobatic planes.
As he said, it's time to move up!
