just WALL it into a hover against the wind then there will be no wingrock because it will go straight from horizontal to vert . then be prepared to gas it a few times to stabalize then find the sweet spot.. biggest problem ive found with hovering the flip in the wind is it is so light that during a torque roll when the left side hits the wind it will hang sideways like a high alpha Knife edge if you are a little late on the right rudder for compensation. I usually (in the wind) as the left side faces the wind have to give almost full right rudder to keep it straight up..Just takes practise
