if it’s any consolation, neither me nor any RTA customer that I know have ever got a reply from Administrator.
The best advice I can give you is to send an email to Oleg Verhovodov ( olegverhovodov@gmail.com ) and ask him what you just asked here.
It was him who sold me the first RTA truck I bought years ago. He’s a good guy.
He’ll be able to confirm your customer status and then send you a link for the model(s).
