There are 2 out there that I know of at the moment.
Flight models are far from realistc, but still fun to buzz around in…
Which is kind of the point of Gyrocopter IRL anyway! LOL!
Not sure if you’ve already found these…but here are some links anyway!
A freeware 007 Little Nellie is availabe on flightsim.to:
And Rara-Avis has released the payware Bulldog Autogyro…Kinda feels like a biplane to fly,
But I think that’s mainly because of the cockpit setup:
Anyway, Maybe these are helpful for you!!
Cheers
