That mix is used for some extreme moves. It does help with wing rock but that's not what I use it for. That mix will let the plane fall straight down in an Elevator. I also use it for Waterfalls and Walls. On a down wind Wall the plane will stand straight up and slide forward 20' before it stops. Same way on a Parachute. A word of caution on this mix. The plane flys terrible with the mix on. For that reason I use the trainer switch on the radio to turn the mix on/off. I have tried it on a regular switch and it almost cost me the plane at the bottom of an inverted Elevator.
