Sure. That is known. But even the 6061 label would be found on the aluminium. And it is not. So what does the Sierra or Cheetah use?

Hi everybody

I am wondering if the fuselage is made from aircraft aluminium? All the fuselage pictures doesn't show any labels which identifies the tubes as aircraft aluminium.

Does anybody know the proper alloy which is used on the aircraft?

Regards,

Wolfgang
