I’ve always wanted to see model matching implemented in a sim, but I’m not sure how complex it really is. Basically, the sim would send out your player model to the servers so it can be used by other players to prevent swapping out the model for another aircraft. This came up when I was doing some bush flying with the BT Kitfox and I was subbed out as the default CJ4. I think this would be a really cool way to improve the multiplayer experience as more and more addons are developed.
