I think Tiger Moth maybe right. My reason for this is when you start a Professional licence, which is what you need to be paid of course, they usually advise getting a class 1 medical before you start, so as not to find out at the end that you are medicallty unfit having spent thousands. You would need to ask someone who is an instructor nad they will tell you. However, I will try to find out for you. I'll ask at the club.
Bye bye
