Regarding the Buttkicker Gamer 2 mentioned in 48RE’s cockpit, David Marsden sent in his quick reivew about the device as follows:
The Buttkicker Gamer 2 is a device that takes the bass from your sound output and converts it into vibrations. You can attach the actual Buttkicker to your chair as shown below.
The lead from this connects to the amplifier (again a picture is below). The amplifier also has a remote that connects to it. Another lead runs from the amplifier to the Sound card at the back of the PC. All the leads are supplied with the kit and it is quite easy to set them all up.
All that remains to do is start your flight sim as normal. You can increase or decrease the sensitivity (it really does not need increasing, if anything it needs turning down).
What I like most about it is you can feel the vibration of the engines during steady flight (B737-800) as that is all I fly. I have not tried it with any other planes. Rolling on the runway is also very realistic. I have only had it set up for one day, so I need to play around with the FSX volume levels to see what difference they make.
If you live in a flat or shared apartment building I don’t think the Buttkicker would be suitable. Unless you can insulate it somehow I think it would annoy your neighbours. Mine makes the whole floor of the flightsim room shake, but I do love it.
It does not impact on the FSX Performance as it gets its input directly from the sound output and the processing is all done by the amplifier. There is no software installed on the PC at all. It is just plug in and play.
