CaptinJohn....

I just checked out the FMS site (http://n.ethz.ch/student/mmoeller/fms/index_e.html) and there seems to be people running Pentium 166's and the program works fine (so they say). The download is just over 6MB and the files once unzipped will be around 20MB.

This is a great sim and you can't beat it for the money. The major complaint with it at present is that with Futaba tx's there is is noise and the planes tend to be a bit jerky (which is fine with me - acts like flying in the wind and keep you on your toes).

Hope this helps you out,
Vance
