The UCDs do some of the best flat spins out there. They will even do a rising inverted flat spin. Not many will do that. The only planes I know that will do them as good are the Mayhems and the Twist. Maybe some profiles. But the UCDs are at the top in this catagory. Gjeffers and Raideron are telling you how. I do mine the same and just hold it for landing.

Very impressive flying planes the UCD.
