I've been using FMS with no problems at all.

It has worked great for me. And furthermore, it has helped me to get back into RC and start flying after 20+ years away from the hobby. I crashed models on the simulator many, many times - and that translated into NO CRASHES at the flying field. Which is much better than I ever flew before.

Isn't that what a simulator is supposed to do? - Helps you fly better? [sm=confused.gif]
My opinon, based on the above, FMS not only is free, it works great too. [8D]

Of course you may be expecting more (I don't know what it would be) from a simulator than just learning flying and various manuvers.

And also, I don't have one of those $$$$ $200+ simulators to compare it to.
But isn't that a bit un-fair in the first place, trying to compare a mega buck computor simulator against freeware - and then downing the free one, because it's not like the other in every respect? [sm=confused.gif]
After all, FMS IS FREE, and the others aren't! (as far as I know)[sm=cool.gif]
