I learned at Leicester last year, getting my PPL just in time for Christmas.
Dave Biddles is CFI so unlikely to teach you as he will do the testing. Nick is the full time instructor who I found to be very patient and knowledgeable. He got me through on the 45 hour minimum, even though I had a "whenever" attitude.. I was in no rush. So one of us was good at least
There are a couple of other part time instructors there also. All the advice I was given was to try a couple of instructors. I was very happy with Nick so ignored it
They just reduced the hourly rate for the Cessan 152 training too, believe it or not!
