Definitely the UCD 60. I've never flown a model airplane with a wider flight envelope. You can get really ignorant with it, yet it would make a good trainer; except for one thing.

All the planes you listed are very fragile. The reason they fly so well is because they are VERY light, due toi the way they are built. IOW, they won't stand much "newbie abuse". I would NOT buy one of these until you can land well, EVERY time. The UCDs, in particular, do not take well to be slammed down onto the runway.

Be sure to take the time to plough through the mega threads on the UCD. There are many nuggets of information in there. The UCD 60 is probably one of the most popular ARFs in history. Seems like everybody had one, at one time or another. There were six at my field alone. What this means is an incredible base of experience, since we all look at things in our own way.
