Hi Aged,
Yes, there are 2 private C172 groups based at Aberdeen and there are usually shares avail in one of the groups. PM me if you want more details.
As for Kinloss I know that slog up and down very well as I used to instruct at the VGS there about - 7-8 years ago and also flew with Moray Flying club. Had to pack that in due to my job however as I had to be on call a lot at weekends hence the reason I bought the C172 share.
Regards
UA
