I remember a model airplane called 'Total Zero' and it was built very symmetrically (other than the gear) in order to make it as 'neutral' a flying airplane as possible. The goal(?) was to eliminate adverse yaw with aileron, Dutch roll and etc. (the only thing it wasn't: a twin engined aircraft w counter rotating props!) The F1 raceplane, Kelly 1D (?) has its fin/ rudder equally distributed on the thrust line to enhance its flying qualities. I reckon the Chipmunk will have this 'snaking' tendency because it is the nature of its design.
