If you are wanting to ask a support help question, the best thing to do would be to find out where the 3rd party developer offers support. You may find it on this list: 3rd Party Support & Bug Reporting
Or, if you are posting a generic help question on how to use the aircraft, you can look to see if they have a Mega-thread about the plane via the search tool, or create a new post in #gd-commsupport:anc if you do not find a mega-thread or another thread about the same question.
