I know it's kinda high priced but I already own A Great Planes Ultimate with a DL 50 and it's falling apart. It's a great flying plane but after a number of repairs, and no crashes or even rough landings, I'm beginning to realise why it's so cheap. I think they used some kind of time release glue that after a certain amount of time, it releases! That's one reason I'm looking for another Ultimate, plus there isn't an ARF that can give you the pride of a kit you build yourself. The main reason I haven't already bought the Proline Ultimate is because it is $500.00 and I can't find any information on it.
