Well I have my 30 cc US dialed in and find it to have two minor shortcomings, it is not as agile as my 120 size US lite with a VVRC 20. The 30 cc is powered by a DLE 35 ra and has more power for it's weight.
The 30 is covered with the worst colors for good vis. Two at our field have added Orange strips on the leading edge. It looks tacky in my opinion but may be necessary as I got into S..t because of it the other day, hard to determine direction briefly. Recovered the plane after a little luck and "Trick" flying. Make no mistake both a good fun planes.......
