I have a UCDO 46 with a Saito 82 and I never fly at full throttle unless Im pulling vertical out of a hover...I had a Funtana 40 with the same engine and I liked it a lot except it had a nasty tip stall which finally did it in Its built well and goes together easily floats in for landings and has an awesome roll rate!!!..The UCDO is very forgiving(more so than the Funtana) and will do all the 3d you want It also floats in like a trainer..Do a search on the funtana and youll gets lots of good info..there is a good thread about the tip stall issue that you should read..has lots of good info in it...good luck!!1
