I challenge @Armand2REP to prove his previous theory:
"China's Z20 is based on French AC352."
everyone wants to know if his new theory is correct or not:bounce:
If his theory is indeed correct, that'd be breakthrough because all the present theories/publishable analysis articles about Z20 is fixated on its link to UH-60. :bounce:
it's a totally academic topic:bounce:
