It seems one of the common problems running the DF727 in FSX and Win7 is the loss of voice calls. I've discovered a free program by Matthew King which will replace some of those and add a little extra. FSFO (Flight Simulator First Officer) adapts to this old bird pretty well. I've only used it less than an hour and it seems to fill a lot of voids. I'm trying to tweak/construct some files that should make use of FSFO easier. There is a newer version v2.1 available elsewhere. A very elegant solution if you miss the V1/Vr calls.

Helps with flaps, gear, even tunes the radio for ILS. I have nothing to do with this program, but it does seem to work as advertise, and being free the price is right.
