Adding aircraft

If i add aircraft into the stream folder and then run the game and spawn them they are still default aircraft. Do i need an extra folder for them or do they just not work at the moment?

Might have added them incorrectly.

they are in resources/mods/stream.

got it working for anyone wondering i renamed the mods folder to assets and changed it in the citmp-server to - assets

You just needed to delete the server cache.
