And just today a flyable version appeared at SimV, with a panel. (Just the plane, not the scenery.)
"...Alphasim freeware AI mdl made flyable in FS2004.Complete 2D panel and outward look but no VC. Water dropping effect added. Conversion by A.F.Scrub."
No mention of whether there's a modified flight model. or whether one is needed.
A few years ago, when I was active in the hobby, I made a flyable version using a JRM panel I found at one of the download sites and the flight model from Paul Clawson's PB2Y Coronado.
