Absolutely agree about the legendary Lionel Taylor - there is nothing he doesn't know, he's been doing it for more years that he cares to admit to
I did my CPL theory with Lionel way back in 1990 and he was around well before then as well. Yes, agreed he's a legend when it comes to teaching CPL theory. He must know that Echo Mark IV better than anyone else (do they still use that fictitious aircraft for CPL theory these days?) I had private lessons from Lionel back then since I wasn't able to attend any of his classes due to work commitments, so you might be able to do the same as well. Anyway, good luck with it all.
