I have not experienced this during dual training, (S2)
When I enter a spin,(S1)
both left and right, first two rotations I get a nose up and down oscillation before it cleans up to a good constant attitude/rotation spin.
Tried different input timing entering but typically - nose up, buffet, full left (or right) rudder, stick back and centered. Control inputs are not abrupt but deliberate and full.
Cg #s are within spec,
Any thoughts on what’s going on?
