Thanks for the pointers everybody.
The problem is that Sywell don't know if they are going to run any courses this year, Old Sarum definitely aren't until the end of the year, Rufforth don't respond, the web site is off and all the e mails bounce, Popham have no plans to run any at all, etc etc.
I get the impression that these courses are so time consuming for the operators that nobody really wants to do them. As there are only about 8 rated course providers in total and some of them are only rated to do flex wing, the options are very limited.
Were it not for the fact that I am too long in the tooth to face the CPL exams for what is just a hobby for me, I would go the JAR route for either fw or rotary or both.
