I have thought about it for a while now, but not being a programmer or modeller myself, I wasn't - and still aren't - in a position to start it by myself.
This morning I thought about it again, so I decided to do something about it! I would be very interested in doing an RAH-66 Comanche sim. I know there is not ever so much technical info on the Comanche but I'm sure we could get a pretty decent model going. Also, it wouldn't have to strictly adhere to what the Comanche was like - we could integrate things that we think the Comanche would have had.
The sim would focus on high-tech warfare, so the Comanche's whole being could be put to the test. Hell, if we wanted, we could even include enemy Mechs!

We wouldn't have to worry about necessarily making 'realistic' battles, as we could go with ideas of 'theoretical' conflicts of future warfare that the Comanche was made in mind for.
As you know, everyone nowadays wants to make and play AH-64D Longbow sims. And there is no real entry right now for the RAH-66 Comanche, and I think we could really push the boundaries. The sims in the past that have featured it, have not been very realistic, although I do like NovaLogic's Comanche series the best out of the ones that are/were available.
I think a sim from scratch would be better than, say, doing a mod for EECH. This is because I don't feel that the existing Comanche in EECH is an accurate representation of what the Comanche would have been about. It would probably actually be easier to start from the ground up rather than re-working the whole thing going on in EECH.
I think we could have some real fun putting in the speculated features of the Comanche, and make them usable, even if they wouldn't have been a real asset.
If anyone also shares my vision, and think they could help and want to help, please get in touch. And who knows, if we got enough people together, we may even be able to make a go of it.
