They're good. Dundee is a great training airfield, (and Scotland's just a great place to fly overall). The aircraft are well maintained. The instructors all have to do the military CFS assessments which, while they're pitched at a pretty basic VFR level, the RAF examiners are very demanding and they are very very fussy in how they want things done. In any case it means your instructor is probably not going to be some Florida cowboy.
