The last i check FMS has parimeters files. In other words you can adjust the center of gravity, off set engines or
clip the wings, add mase. It also has photographic sceneries too...at least i do.lol thousands of them.
i also have thousands of modles too. People make them all the time and upload them for free.
You can make your own models and sceneries if you know what you're doing.

How in the heck is a sim manufacturer going to create my model ? The ones i build and bash/modilfied ?
My enigine types, prop configuration ?

I can't give the G3 a fair evaluation from a trail version, the zoom is set back too far.
but i do hate those funkie swirls in the in the trial version scenery, it hurts my eyes.

Okay FMS might not be the greatest thing on the planet...but it'll keep the high dollar sims on thier toes.
and give it a heck of run for the money.

Whatever sim you use, i guess the trick would be is to tried to dial in your tx and your model.
i didn't spend $300 on a computerize TX for nothing
