Good spot Waldo. Wondered the very same myself.
Agree that the aerobatics are OKish but IMHO a bit rough around the edges. Compared to Brian Lecomber, Nigel Lamb, Will Curtis, Richard Pickin, Xavier De Lapparent, Pete Kynsey, John Harper, Alan Cassidy, Paul Bonhomme, Steve Jones, Mark Jefferies, Gennady Elfimov, Nikolai Timofeev, Diana Britten and quite a few others, it's not very polished! Yet through relentless self-promotion, and sponsors (albeit minor) who insist on using the Extra 300 as a flying hoarding, he'll continue appearing at displays.
It's a crazy world we live in!
