Just putting this out there in case anyone is interested. I use the ButtKicker Gamer for DCS. It adds a great deal to the immersion factor when you can
feel the Hornet's catapult stroke off the carrier. They sent me a 20% discount code to share with anyone who wants to use it. Says it expires 10 OCT 2018.
