Up until recently I was of the opinion that nothing was ever solved with a FFR. Whatever problem I was having was still there although these were mostly nuisance faults (engines being quirky) and probably related to my layout DCS signal strength. However, I now have two events where FFR saved the day. The first was a PS3 Dreyfuss Hudson that kept wanting to displace an existing engine location every time I tried to add it. At one point I had both engines coming on at the same time. I deleted both engines, did a FFR on both on a test track and added them back. Problem solved. The other day I got one of the really cool red and white Premier TP&W RS11's. It added just fine and started ok but when I tried to adjust the sound it emitted a high pitch squeal that wouldn't stop. Everything else worked but that was the only sound I could get. Ugh. So I did a FFR and re-added. Voila, problem solved!
I don't know how FFR works but I'm glad it's there. Would be interesting to know more about the history of that feature. 
It's a shame Barry has passed. His book really brought DCS to life for me.
