As far as I know, this SU-25T is the FC2 version ported, which means that there is no clickable cockpit.
You can use its weapon system, but you have to use the keyboard or HOTAS to do that.
Its a free gift with DCS world, so I do not blame them for not doing a clickable cockpit, not to mention that this is one hell of a plane to fly SEAD or CAS in.(Althoug I must admit, you need some serious practise with it to do it right
One limitation I am aware of, that you cannot fly it in multiplayer if you do not own any other DCS products merged into the DCS World. (So currently only P51 counts, BS and A10 yet to be patched to be part of it).
You can always use the single mission editor to do some serious flying.
Hope I helped.
