I agree with Pigsy.
Very competent and professional instruction from Groupie(aka David Schouller) at Old Sarum. If you can cope with military style precision that he portrays and expects, you learn huge amounts. You also do your course on a taildragger. Great experience and very useful when you want an instructors job.
Useful tips for completing the course with David:
Be on time for a 09:00 start
Expect to be called Mugsy forever.
No slacking or you'll be reported as a deputy cretin for a court martial.
And finally,
Oh Hi!!
