I have a Honeycombe yoke and Warthog joystick. When I use these in XPlane with linear settings, I get almost an exact one to one movement on the screen when compared to the physical device. The Cessna 172 is particularly good at demonstrating this. This is how I like to fly and to me seems the most realistic (and with a zero dead zone), although I understand that many would find this too sensitive.
With MSFS sensitivity set to zero, I would also expect a linear response, but this is not what I see (on the roll axis in particular). There appears to be a default sensitivity built in and in order to get something that resembles a linear response in the Cessna I have to set the Honeycombe yoke to about +60 sensitivity.
I suppose it’s not really a problem, but it doesn’t seem right to me…
Also, can anyone explain what reactivity does?
