I was going to rate this 4 stars until I realized that this kit was a real challenge for me and it was gratifying trying to meet that challenge. The kit contains enough hardware for 5 versions of the Tornado. Three of the 5 are IDS and 2 are ECR. It contains 6 sprues including 2 A sprues (one for each IDS or ECR version). The instructions are complicated on some pages and requires rereading several times. This is not a kit for the faint of heart, but if you take it slow and easy, you will get an outstanding product. The piece fit is very good for the most part and there is very little flash. I'm not 100% pleased with my finished product, but that's my fault. I plan to build another one learning from the mistakes I made on this one.
