On my Funtana I have 100% spoileron mixed in. That is when the ELEV is all the way up(down stick) the AILEs are all the way up. It also helps to do them inverted. It will wing rock upright. This is the same mix I use for waterfalls(end over end). Please note I have a bunch of throw and my CG is way back. You did not mention what plane you are flying. Maybe it wont 3D no mater what the setting?

A word of caution. I have my mix on the trainer switch so I can quickly disable it. When I first set it up it was on a regular switch. At the bottem of an elevator the plane is pretty hairy with a 100% spoileron mixed in. I had to go into a hover flip the switch and then fly out. With it on the trainer switch I can just let go and throttle up to fly out.
