I understand fully the effects of mass and inertia. Just commenting this one continues further beyond anything else I have.

Most of my other A/C will stop a roll or snap as soon as I neutralize the controls, (my friends Ultimate does EXACTLY what you ask of it). I have a few other bipes in the queu, including a PICA WACO I just grabbed that needs a bit of work, so perhaps one with 4-ailerons will behave differently.
