The software! and to some extent, the hardware.
On the hardware side, mozaās a big company and has the resources to make a pretty solid, well designed box. Many people have bought it based on their popularity in racing sims. But i dont think they know anything about flight.
The VPforce āTelemFFBā software is open source (of which i am a heavy contributor). It drives all the effects and forces using simconnect telemetry from msfs. (it also reads xplane, il2, dcs, and bms)
For msfs, it acts as the axis controller. So you unbind in the sim and TelemFFB sends the axis position. It also reads the trim position, and offsets the center point so that you trim to ārelieve pressureā.
The software has gone though a lot of rapid changes recently. 2 years ago it was little more than a command line program with a .ini you had to edit, now itās a pretty GUI with sliders that you can manipulate real-time. Moza took an earlier version of this, called it their own and has rarely updated it. (did they figure out trim yet?) Meanwhile, on the VPForce discord, people ask for new features and itās delivered in a short time.
The Rhino itself is the turnkey stick base- but, for the DIY types you can order just the motors & usb board, and make them into whatever you like. Get larger, more powerful motors and build a āMonster Rhinoā. Make a completely custom cyclic. Adapt to your pedals. Even a collective and motorized trim wheel, which can be either moved by hand or with the simās up/down trim buttons.
Perhaps the most impressive is with HPGās H145 and H160 - (we had their help in development) with cyclic, collective, and pedals all in vpforce, when you activate the upper modes, all the controls literally jump out of your hand and fly the heli. itās really wild.
Recently we pushed out a big 2.0 upgrade to TelemFFB which makes it easier to manage the hundreds ( ! yes hundreds, not a typo) of settings available.
At this point, I donāt really want MSFS to get native FFB. I donāt think theyāll get it right.
