I have built this kit many times - The hardest part is all the masking for the upper structure - with all the clear parts. With that being said the parts fit was excellent with little to no flash and clean up was a snap. The instructions were a little confusing but reading them several times and they will make sense. The only damage I had was one of the tracks was a little miss-formed but I put that part of the track to the inside and it looks great. I would recommend this to modelers that don't mind the taping and taking time to get it right.
