Just another thought on the medical - what they're really interested in is that you have good vision and hearing, and that you're not going to become incapacitated whilst you're flying the family around, for example due to a diabetic hypo, epilepsy or any other cause. As far as I could work out, they weren't interested in your general health and the tests (e.g. blood tests) weren't chosen to provide information on your general health.

I was initially somewhat surprised to meet a few fighter pilots and airline pilots who were carrying rather more weight than they should. So don't let it put you off.

thing:Ah, that would explain it. You've used the POH figure for the empty weight. I can guarantee you that the actual empty weight figure on your particular aircraft's weight schedule will be in excess of 1080 lbs. Most 152s are at least 1170-1180 lbs empty weight. So that will knock around 100lbs off your usable load. You'd then be struggling with two adults each over 78kgs - a moderate weight for middle-aged males these days.

If its learning to fly your are interested in, it might be worth looking at the microlight, paragliding side of life both of which are well provided for in south/central Scotland.
Another option might be to try gliding. The main clubs in the area are; Edensoaring which is open 7 days per week near Penrith, Portmoak near loch leven or Deeside club at Aboyne. Converting from gliding to power can be a cheaper route than the obvious flying club route.

Portmoak is 7 days a week, all year round, weather permitting. I think Edensoaring stopped when the clocks changed and will reopen when they change again next March.

If the OP is in central Scotland then Aboyne is a long trek.

Microlights at Strathaven and Balado will probably be open 7 days a week.
