Mine is in the filling and priming stage, so I can't give any flying reports. I would recommend being a master builder as it pushed my building skills to their limits. The wing does have a cool built-in jig for straight alignment during construction. The plane doesn't really resemble the old Dirty Birdy as it is stretched out extremely long, the fin and rudder are huge, the wing is really swept back like an Aurora, and the stab is really thick. These changes, however, make the plane look quite a bit more attractive than I remember it being. It's fairly light, mine is about 2.5 lbs getting ready for paint. I'm planning on a side exhaust OS 160 so I can route the exhaust on the right.
