Will people here please stop patronising newcomers with that sort of red capitals shouting?
30 seconds with the search function should convince you - never, ever, ever pay anything up front to any flying club.
Do you realise how useless that piece of advice is? By the same logic, never, ever go flying on a light aircraft. A 30-second search on this forum will show you how many people have killed themselves that way.
What the OP would find useful is getting an idea of what the
risk is, or in plain English: how many people lose their money in schools gone bust vs. how many people pay upfront and get their licence. Knowing only half of the picture is pretty much useless.
Oh and yes, I did pay upfront, much more than two grand; got my licence and made savings in the region of half a grand. I'm glad I didn't heed the invaluable advice that you find in this sort of threads.
