Yes, there were serious issues there, but best not to air them on a public forum. For the time being... The powers at Gyropedia Towers were apprised of the shortcomings in the instructor last year.
DB was the examiner on the day, and it went well. (not enough left pedal in a spiral dive, was the only wrinkle, but he gave him another go)
DB has been involved in gyros longer than Ken Wallis (since 1960) !!
