Legal

RCFS is released under the BSD License, which you can read in full here: BSD License

Yes, reading licenses is boring, so here is the readers-digest version:
The software is free of charge, and free to be used by anyone
You can do whatever you damn well please with it, as long as you dont remove the authors names from it
We dont provide any warranties for this software

I have also one other thing to mention here.
People have been asking me about the visual resemblence between Reflex XTR(r) and RCFS.
RCFS is in no way illegal, an XTR "knock-off", nor does it come with anything that is in any way belonging to or copyrighted by Reflex Products.
RCFS can however use model-files in the XTR .mod fileformat, and the way we generate the scenery is similar.
