My cam and pin operates perfectly but once the limiter was attached it fowled on the leg when moved into the knee up position... it was only just short of full extension and not concerning for this build but I would like others to be aware of it.
So ... what you're saying is ... the pin in the limiter should be slightly higher up? For those of us using your thread as a guide-line to alter/upgrade our Revell AT-AT ... it's crucial for us to at least know to the millimeter in order to achieve ... perfection!
I.e. How did you attach the legs to the hips?
