Here is a controller profile for the Su-25T included in DCS: World. It is a pretty fun aircraft to fly - if you've got a good control layout! This profile should be a great starting point for anyone with a HOTAS Warthog that may want to log a few more hours in the Frogfoot.
These two .lua files for DCS: World should be all that you need. Just Load Profile in the controls options and select the appropriate .lua.
