Pappy,
I built the kit (out of the box) a couple years ago and really enjoyed it. There are a couple places where you might have some problems, though. The air intakes on the wing are too long and will need to be trimmed a bit to avoid the exhaust shroud. The canopy can be intimidating, too. I used a lot of Tamiya masking tape and patience to mask and paint it. If memory serves, the cockpit fit together well and I don't recall having to use much, if any, filler for the wing and fuse joints. All-in-all, it was a nice build. This kit screams for superdetailing so one of these days I'm going to pull another one off the shelf and do it up with some of the resin products that are available. Have fun with it.
Have a look at the finished product:
