I changed my prop out from the TBM which I was turning at around 5600 on a DA100 to a Xoar of the same size (27X10) and I went from having very little pullout to having respectable pullout from a hover. There was a noticeable increase in performance just about everywhere in flight. I haven't put a tach on the Xoar yet, but it has more of a ripping sound on the ground than the TBM ever did, and the DA just seems a bit happier turning it. I'll get a tach on it next time out.
