VRC Pro is awesome!
I just tried the free demo from the website and this piece of software is wonderful!
...Yes, it may be outdated in terms of RC models, but the simulation is really impressive and feels great!
I understand the barrier to entry needing an adapter for most transmitters, but if you have something like a Noble NB4 you can just plug n play with a usb cable to your PC!
Highly recommended. Underrated IMO.
