Like bodie I also dropped in there not so long ago and found them all very welcoming. As far as i could tell ther was both a heli and fixed wing school with R22's and C152's.
One thing to think about at welshpool is possible problems with the weather - as its situated in a valley i think i'm right in saying no solo flying if the cloud base is less than 2500ft - although this may have changed by now.
