RE: Snap Roll (no arguments, please)
Well, honestly speaking our models do not actually stall in a snap roll, the best we can do is imitate a full scale snap where in which a wing does stall. The way that i personally snap is to switch to high rate Aileron, then pull all the way back still on low rate elevator and rudder with the aileron slightly delayed, Do Not let go of the sticks and let them go back to center on their own, bring them back to center and tap opposite which makes it crisp, and actually ends where it should.
