I also fly from Wellesbourne, but with Wellesbourne Aviation, which I have found very friendly and I must say cost effective. No landing fees at Wellesbourne, rarely held at the hold waiting for traffic, but there are exceptional days, this means paying for less time on the ground, brakes off to take off time.
You will however have a number of lessons cancelled due to crap weather, or have your training re-arranged because crosswinds are out of limits for solo circuits etc. Towards the end of your training you will need to take time off work (if you have work) to get longer flights ie QXCs in, because you will need the aircraft for half a day and weekends book up in advance by up to 5-6 weeks. You need to stay current.
Just got my QXC solo, revision and skills test to go, cost to date, don't know exactly but in the order of £5,700
