The only warbird trainer out there so far is this RTF...

I doubt there's 15 hrs to put into that, though... if they had an ARF version, that would likely be 15hrs or so.
If you are going to fly it, get an ARF trainer... if you aren't going to fly it, just get a static model and build it... it's not worth investing $$$$ in a RC model if you won't fly it!
