Good luck writing down ATC instructions with your mouse 
Also, personally, after X-Plane excellent VR controller implementation I feel crippled using the mouse in MSFS. It’s insanely irritating trying to twiddle knobs and encoders and switches with the mouse, and almost impossible to operate GPS and glass cockpit in flight. I don’t know how people can find it acceptable and prefer it to actually pressing the buttons and rotating encoders and operating switches with a VR controller with full muscle memory and depth perception working. But apparently many people do. My theory is that they mostly consider VR an improvement on TrackIR or a better headtracking display. While those who appreciated VR before the sim treat it as a crippled, or just not a complete “half-VR” implementation. For a VR enthusiast no controllers means not a full VR experience, period. It’s all about immersion for us, and not being to interact in 3D is a terrible immersion-breaker. Mouse is a crutch that translates 3d movements to a 2D device, making our hand that is capable of 3D operate in 2D on another plane, and translating the motion back to 3D, mapping it into a 3D environment. It’s insane, if you think about it, when you can map your full motion directly into 3D.
With an exception of a real yoke and possibly throttle, everything else is best done with controllers, by far.
Having said that, I’m planning to improve it further, so I’ve built a full 8-axis throttle quadrant (including analog reversers), custom pendular yoke / joystick on hall sensors, left HOTAS-stile throttle with switches (convertible to helicopter collective control), switch box for electrical/lights/gear lever, 6 dual encoder + 8 button box for directly controlling radios, barometer, AP, GPS etc. Oh yes, and all this, along with a Wacom tablet (for writing down ATC instructions) is mounted on my home-built motion platform with vibration transducers. This should mean that I’m able to operate virtually everything I need in flight and in intensive workload moments (take-off, landing, approach, climb) without grabbing the controller, and mostly use the controller during cold start procedures and for programming/operation of FMC/G3000 and the like. G530 is fully controllable by my encoder box, and some of the G1000 functions are too.
Can’t wait to be able to use this together with VR controllers. (work in progress photos)
So I’m aiming for the best of two worlds, basically. But even with all that control under my fingertips, there is no room for the awful mouse here! I’ll be so happy when I’ll get rid of it.
This is just my personal opinion. Let people make their own choice… But having 500+ vote and 1st place in the wishlist, this feature is clearly in highest demand among VR MSFS users.![image|690x414]
