Mike, I expect you know this already, but for others browsing this thread I will just recite the inputs to an axial or almost axial roll:
roll right with aileron, touch in left rudder and release, touch in down elevator and release, touch in right rudder and release, touch in up elevator and the roll is complete. The left rudder should be touched in just before 90 degrees, the down elevator just before 180 degrees, the right rudder just before 270 and the up elevator just before 360. Rolling left the rudder inputs go the other way. Four-point rolls you hold left rudder, down elevator, right rudder at the 1/4, 2/4, 3/4 points.
