Since youre in Sheffield, if you can go up the road to Full Sutton, you can go and have a go in an S2A, its about £200 an hour, but most aeros flights are for 40 mins, so that about £130, and you can log it towards the 45 hrs required for your ppl, and towards the 2 hours of stalling and spinning you need to complete.
Im currently flying there in the firefly, trying to get sufficiently proficient to fly in the beginners aeros comp at sherburn, where both myself and MikeeB will be competing for last place.
