I was an instructor at Panshanger and had a great time. They are a very busy school with lots of flying, in my time there i had over 30 students on my books. It was a six day week (mondays as day off) £10 per day + £10 per hour not the best paid but you will build hours fast. The only downside is when the weather is bad you are expected to still attend and do jobs like weeding the flower beds and cleaning the fish pond etc but i suppose thats what has to be done to get where you want to get.
Great school, Great people, Good luck.
