The rising flat spin is hard to do. I think the main thing is to have a very low wing loading. The way you do them is the same as an inverted flat spin. Then you manage the ailerons, rudder, elevators and throttle (about everything I guess) and the plane comes to a full stop while spinning, (pinwheel) At this point you feed a little more down elevator and pick up the throttle. The plane will pick the nose up just a bit and begin to rise. The challenge is to manage all the surfaces because the plane really wants to roll out the flat spin. With the UCDs and the Mayhems this maneuver is pretty easy but you do have to really juggle the sticks. I was able to do it moderately with my Twist. Those are the only planes I've been able to do it with. All others seem to just roll out of the flat spin. My AirWild is close. I've only tried it two or three times and it seemed like it would do it with some coaxing but I was unsuccessful. I will keep trying with that plane.

It is my all time favorite maneuver and looks sooooooo cool when you do it. On a calm day I'm brought the plane down to about 15-20' from the ground and was able to get a rising flat spin up to 50' or so. Most of the time I can go up 10-15' before the plane rolls out. Sometimes adding spoilerons helps. Sometimes I'm not sure it does. But I really have to be on my game to do them.

It's interesting that the UCD is so good at this stunt. Yet it lacks in many other areas. Kinda neat though when you can do something that the many thousand dollar planes can't.
