Take a look at the stab size on a cap and on an extra..
You will notice a difference. That will effect a way a plane snaps also.

Cg can make a plane snap more or less.. On both my cap and extra my cg is set so critical that if fly droppings fell on the tail the planes would be unflyable!
Novice flyers should set their CG 1/2 inch ahead of the recommened cg starting point for the first bunch of flights till they get a feel of the plane's snap tendencies.
