Just got done transforming mine a few times and here were the problems I have. The majority of the problems were related to the right arm:
1. Right hand is way to loose. The gun keeps flopping around.
2. Right fin does not go in all the way, but still is 95% in.
3. Right missile hatch does not open all the way and go flush with the arm, but still opens 95% of the way
Over all the sculpting is fairly good and everything is super tight. I don't have anything floppying around other then the gun hand. In fact, it is so tight that I broke the hatch that you have to open to allow the cockpit to set in the back during Battloid. I thought it was opening quite smoothly until it was in my hand. It broke right at the hinge, and it is a clean break so I can put it back in place during guardian and fighter mode.
Over all I'm pleased with it. It looks a little fugly in fighter mode, but it you like something to be perfect you might has well do it yourself. I'm still looking forward to the next Alphas and especially the Shadow fighter.
