i have been rather pleased with the quality of the F-16, non advanced version, i have. appears to have been painted after the molding and done well at that. the gear door cylinders could be better, but are rather easily worked on or replaced. their customer service has been great for me. i managed to bust 2 of the little tiny O-rings that are on the air valve plungers, and unable to locate any here locally, Mr. Chin in china sent me 12 new ones already mounted on 6 new plungers for just asking. i would have gladly paid 50 bucks for just 1/2 dozen O-rings. i have 5 plungers with O-rings left, if anyone else manages to dumb up theirs<G>.
