Anyone built this kit? What are your impressions and how does it fly. I'm looking at this as a possible for my fourth plane.

I am currently building the spitfire. What I can tell you is the kit is good. However, certain points must be considered:

If using retracts, must build up the area arount the wheel well.
Also, the CA hinges go into only 1/4" balsa. I recommend adding support to the area behind the hinges.

These are my recommendations at this point.
