IIRC the original was downloaded from the FAI web site.
In addition to the sticker you need your national ID number somewhere on the model, but that can simply be drawn on with magic marker.
Typically in processing they will apply another small sticker partly over yours as proof that the model has been processed.
I have also seen them use ink stamps or initial them.
there were discussion about the FAI sticker and I would like to get information about this from contest organisers. Is it allowed to make an own sticker which includes the same information than the original one? Can I scale it a bit smaller? I want to be sure our models are completely legal so that there will appear no surprises at the model processing.
