You don't mention transport to the airfield. You obviously can't drive yourself at 16, so how are you planning on getting there? Poor long suffering parental units? Give distance and travel problems some thought please....
Maybe a couple of weeks at a time on site would work out for you. And a bit less time posting on PPrune might help, too. Get your hours signed up anyway. Despite the doom merchants a PPL in 45 hours is possible if you are reasonably talented, work hard, and use a lot of self discipline about when you fly. I suppose the poor old folks are paying for this, so try to save some of their money for touring later on, eh?
I understand Its It's also a radio service, not a normal ATS. This would not affect anything right?
How could it? The radio does not fly the aeroplane.
