revalidating
Suggest not, at the clubs I fly at, there are not enough students to go-around and a lot of bitterness between instructors. The pay is £10 per hour flown and I know one full time chap who did a full months work in November (5 day week ) who flew only 17 hrs!!!!!.
New instructors coming along are resented and its becoming a massive load of grief and not worth the effort. You will get a better return on you money by putting into an ISA.
