I have a UCD 46 and it's a fun 'sport' airplane...more so 3D than pattern. I'm flying it with an OS 46 and it flys fine...would be better with the 50, but i had the 46 so that's what's in it. The 50 is identical in size so it would be an easy swap. It would do 3D better with the 50, as the 46 is just enough to hold it in a hover...barely...briefly....the thick wing lets it slow to a crawl for landings...keep the throws tame to start and increase them as you get used to the plane, if so I think you'll find this a nice plane to get back into the swing of things with. Welcome back! [8D]
...ps...don't ask about 'flippty flopp 1'...
