The snap roll is an auto-rotation maneuver in a stalled condition. During a snap, one wing is stalled while the other is accelerated about the roll axis. This creates a sudden roll-rate acceleration that you cannot obtain by simply inputting aileron. To achieve this condition in a model, several inputs must be given, including elevator, rudder and aileron. For example, you can perform an inside left snap by programming the mix to simultaneously apply up-elevator, left rudder and left aileron for 1 to 2 seconds. Recover from the maneuver by neutralizing the sticks and immediately adding right rudder to correct your loss of heading.
