He did say single-engined though. Aerodynamics don't list that as an option
Hmm... I was under the impression that they did SE-IR as well, as they also have a fully equipped single-engine sim, but on reviewing the literature I have, only ME is mentioned. Still, nothing that can't be cleared up with a quick phone call.
btw, can I be curious and ask why (both of) you are going for a SE-IR?
