I just run a 2nd instance of TelemFFB to talk to mine. They can produce the same haptic effects that the Rhino does (at least where the X axis is involved). (I also run a 3rd instance for my collective)
In general, there's not a whole lot of pedal specific effects that could be created. The two primary ones being dynamic forces and of course, trim. Nosewheel shimmy is another. I have added both dynamic forces and shimmy to TelemFFB for MSFS. Trim is a bit more of a problem.
DCS, unfortunately, doesn't support any of these. It's FFB is limited to X/Y joystick axis. What's worse is that it will send ALL FFB events to EVERY FFB device it is talking to. This isn't usually a problem since you will get the native effects like buffeting, but it also means that the native trim movement of the control stick will be mirrored on the pedals (a bigger problem for helicopter force trim).
The next Rhino firmware should make it possible to override some of what DCS does in that regard.
Today, I switch between two VPforce Configurator profiles (no spring for Heli's, sticky spring for FW)
