Force feedback is really neglected in flight sims. If the Logi 940 had been made using better quality parts I might have stuck with it. I know Oleg didnt like FFB so I doubt anything can be done for pedals.
I remember this and wanted to try it on my Warthog. http://dangerdogz.com/forums/topic/7464-give-your-x52-some-feeling/
So I bought a cheap rumble pad as the Saitek wouldnt work on Win 10. I checked it would shake using 1946 and ripped the guts out of it, mounted the board in a plastic box and used the Saitek rumbler as the game pad was a bit light weight. Last night on coops I was pleased to feel the shake as I approached stall and also felt the effect from flaps and u/c hanging in the airsteam. Well worth doing.
As I have replaced the potentiometers with rotary encoders for the elevator and rudder trims I will give this another go. I try to keep controls the same as possible for my flight sims. I needs a lot of clicks for the elevator trim to move from max up to max down in Clod.
