I did last year's event 4 months after re-qualifying as a PPL with 2 vets and found it enormously rewarding.
I had to pick mine up from Sywell and it was the first time I have had to do 4 flights in one day, very tiring but great fun.
Having an ex-canberra CFI in the RHS doesn't add to the pressure at all
I have registered for next year
