The build of this kit went pretty smooth and the same as the F35A kit. My only struggle were the bomb bay doors which was minimal. The bomb bay provides enough internal pieces to fully detail it!! One of my favorite areas to get that fine brush out and detail it to your skillset. The kit offers both extended and folded wings that can be changed out at anytime. Both wing tips can be made with missiles attached. Simply inserted. I am not an AIM9x fan so i used 4 Aim120’s from my extras as you will see in the photos i submitted. For the quality you get, the price is right in line. Everything fits together well and you will definitely be happy with the results.
