On another note, a 50% share i've been offered, £200 per month each.
I pay £115 per hour lesson right now.
If I had this 50% I'd pay £22.50 for an instructor.
£22.50 instructor
£35.00 fuel
£ 9.70 landing fee
£67.20 hourly rate total assuming 1 hour lesson
that's £47.80 saving so if I had 5 or more lessons per month i'd be saving.
