The Virpil mounts are great, .. and work incredibly well, .. especially for the price.
I got mine last month, .. and I don't how I managed without them.
Virpil have mounting plates specifically for the Warthog Throttle and Joystick. I also got their extension set, and am using the 10cm extension with the Joystick.
.. which is what I'm using for now, .. as my Virpil MongoosT-50CM Flightstick has arrived in the country (South Africa), .. and should be with me any day now.
Once their new Throttle is released, .. I'll be getting one of those as well.
So, .. my advice is, .. get the mounts, .. they are easy to work with and use, .. and aesthetically, .. they kinda look like aircraft parts ..
