The 'sim' that Fast will be using is a one used by a few operators for IR training. It is overly sensitive, usually based on a Jet ranger etc, runs on Microsoft Flight Sim2002 and is only a FNPT2. (Procedural Trainer) It is not intended to teach you to fly so I wouldn't call it a simulator as such, but I guess it can't hurt. For what you pay per hour, it'd not cost much more to use the real thing (cheap R22)
I speak from experience having spent 40 hours in one of those boxes!!!
