I had the Extra (72" wing-120 size with a Saito 180) and the quality is hard to beat. The finish was imaculate! They are a bit different from other ARFs in that they are built very solid. The problem with this is that while it makes them very durable, it also makes them a bit heavier. Even with the bigger engine I still had to add quite a bit of nose weight to balance. Still flew good though.
