@ides304 I cannot speak to why the team have areas of the support forum locked for only users, but I can speak to the incredible product they have produced and the subsequent support level provided. You will not find a better plane in XP11 or this level of support.
why would you require support for a product you don’t own? Their discord will provide all the answers you seek and the team is highly active within it.
I have zero affiliation with inibuilds, but personally I think the A300 is second to none and their customer service post purchase cannot be matched.
just my ten cent
