At present Tayside don't have any aerobatics instructors as such, although I'm sure some would be willing to demonstrate the odd manoeuvre. I was teaching aeros at Tayside (Dundee) until recently but I've just joined an airline so can't do anything at the moment, however it is my intention to do some more in spring/summer so if you're still going to be there something can possibly be arranged.
They have Cessna 152 Aerobats (not Acrobats) which will do basic aeros; the Katanas can't (in the UK anyway). Don't worry at all about asking them - you won't get anything if you don't ask. The CFI is a chap called Bob Malcolm - good egg - he'll happily answer any of your questions.
